BenQ-W4000i-HT4550i-award-banner - Projector Reviews - Image
For this review, BenQ provided the w4000i, which is the global version of the HT4550i with identical features and performance.

The BenQ W4000i/HT4550i is the most recent addition to the company's growing family of LED light source projectors for an HDR home theater. While I live in the US, BenQ gave me a W4000i, identical to the HT4550i but sold in different regions.

The W4000i displays a 4K UHD (3,840 x 2,160) resolution using a brand-new Texas Instruments (TI) 0.65" Digital Light Processing (DLP) Digital Micromirror Device (DMD) with XPR technology. With an MSRP of $2,999, the W4000i/HT4550i replaces the company's highly successful HT3550i.

The introduction of the W4000i makes it the third 4K UHD projector the company has introduced in the current projector line-up. BenQ has expanded the use of its high-performance 4LED light engine used in the X3000i gaming and GP500 home entertainment projectors. Click on the links for our detailed review of those two BenQ projectors.

The W4000i/HT4550i is the first 3200lm 4LED Android TV 4K home cinema projector powered by BenQ's exclusive 100% DCI-P3 CinematicColor and HDR-PRO technologies for under $3,000. Designed for AV content fanatics and movie aficionados, the W4000i delivers 4K image quality with cinematic color reproduction. The W4000i can display 120’’+ 4K HDR pictures with unrivaled, long-lasting HDR color accuracy and greater detail in bright and dark scenes.

Designed to bring users an immersive big-screen experience for movies and gaming into the living room. Packed with an impressive list of features and powered by BenQ's cutting-edge technologies, this projector offers users a cinematic experience at what looks to be a very competitive $2,999 MSRP.

The BenQ W4000i's 4LED light source really is the heart of this new projector providing a wide yet accurate color capability. BenQ says this new projector shows true colors as originally filmed. BenQ calls this CinematicColor an exclusive design that provides users with accurate color reproduction. BenQ is also providing users with a new WIDE COLOR GAMUT (WCG) mode that, when enabled in HDR mode, reproduces 100% DCI-P3 color performance that is 1.3X wider than other DLP 4K projectors with Rec. 709 color gamut. Whether you're watching movies or your favorite shows, the picture quality is top-notch, with vibrant colors and incredible detail in bright and dark scenes.

Benq HDR-PRO Technology - Projector Reviews - Image
The BenQ W4000i/HT4550i provides high-quality 4K images at a very competitive price. 

Over the past few years, BenQ has pushed the envelope with its 4LED technology's ability to produce higher and higher brightness. The W4000i exceeds their award-winning X3000i gaming projector by offering a manufacturer rated 3,200 ANSI lumens of brightness. BenQ has not only increased the brightness of the W4000i but has done so while using a larger 0.66" DLP imager.

The new DLP imager used in the W4000i I achieves what BenQ calls true 4K that displays 8.3 million distinct pixels regardless of the number of native pixels on the DMD chip. This larger chip must only double the DMD's native 2,716 x 1,528 pixels, unlike 0.47" DLP imagers that must quadruple 1,920 x 1,080 pixels to display 8.3 million pixels on the screen.

Whether you're watching movies or your favorite shows, BenQ's exclusive CinematicColor and HDR-PRO technologies should provide accurate color reproduction and an exceptional range of brightness in both bright and dark scenes. This is accomplished by leveraging BenQ's enhanced HDR tone mapping via the company's DYNAMIC BLACK technology. While most modern 4K DLP home projectors support correct HDR specs, BenQ goes much further on the W4000i by adding their Dynamic Black technologies to increase contrast and dynamic range in HDR mode.

Benq Ht4550I Local Contrast Enhancer - Projector Reviews - Image
Darker Black Level, More Optimized Contrast Details, and Higher Stereo Perception.

BenQ's latest HDR-PRO technology includes a new Local Contrast Enhancer, an advanced algorithm that divides every scene into multiple zones and independently adjusts gamma for each zone. With Local Contrast Enhancer enabled in HDR mode, the W4000i preserves more details in bright and dark areas and enriches the depth of the 4K HDR picture.

The W4000i projector has a feature BenQ calls CinematicColor DCI-P3 technology, which is said to enhance on-screen colors. When the projector is in HDR mode, it is now possible to widen the color range from Rec.709 to 100% DCI-P3 by enabling the W4000i's brand-new Wide Color Gamut (WCG) option in the projector's ADVANCED PICTURE menu. WCG mode significantly impacts red and green tones, covering 67% of the BT.2020 standard. Compared to projectors that only support Rec.709, the W4000i can map colors closer to the BT.2020 standard. This new BenQ projector should be able to reproduce colors with greater accuracy creating lifelike, vibrant content.

Keeping with BenQ's history of shipping accurate factory-calibrated projectors, the BenQ W4000i uses an optimized DCI-P3 color table to ensure spot-on color reproduction. Theoretically, no matter which unit a customer purchases, the colors should faithfully represent the creator's vision in the content being watched.

Equipped with a Google-certified QS02 Android TV dongle, the W4000i provides users access to one of the largest Android TV content libraries available from the Google Play Store. With over 5,000 native apps, Android TV opens the door to a world of entertainment. In addition, W4000i's Wireless Projection allows you to cast your favorite entertainment apps, movies, TV shows, music, games, sports, and more directly from your Android or iOS device, Mac, Chromebook, or Chrome browser.

For the first time, BenQ has included full support for Netflix. This is the Netflix app without a customized launcher or sideloading an application. Thank you, BenQ, for finally including this long-missed feature!

Benq Ht4550I Projector Cinematic Color - Projector Reviews - Image

BenQ's exclusive CinematicColor technology guarantees accurate cinematic color reproduction with calibrated 100% Rec. 709 coverage and Delta E ≤ 3* for 1080p Standard Dynamic Range (SDR) movies as directors intended. In today's 4K environment, most 4K content, such as Blu-rays and streaming movies, are produced and mastered in High Dynamic Range (HDR) and DCI- P3, a wide color gamut standard defined by Digital Cinema Initiatives (DCI) for professional digital cinemas.

With the WIDE COLOR GAMUT option enabled in HDR mode along with BenQ's Local Contrast Enhancer, the w4000i is able to bring out lifelike colors and greater detail in bright and shadowy areas on your 4K big screen.

The W4000i provides 1.3X zoom, 2D lens shift (vertical 0%-60% and horizontal ±15% max.), and 2D keystone correction for easy installation, setup, and operation even in a darkened room. This is going to be an exciting projector to review.

The BenQ W4000i, like most BenQ projectors, offers a modern design that balances style and functionality. The W4000i is a good-looking projector with a blend of matte and glossy surfaces. I love the black color scheme BenQ chose to use on this projector. The various dark tones make this projector look sleek and should keep it from being a source of unwanted reflected light. It looks great in my living room. The BenQ W4000i measures 16.55" W x 5.32" H x 12.28" D (420.5 mm x 135.3 mm x 312.1 mm) and weighs 14.55 lbs. (6.59 Kg).

Like most BenQ projectors, the W4000i doesn't disappoint in design and ergonomics. Conveniently located on the right side (when looking from the rear) are easily accessible control buttons for menu access and navigation. From this control, the panel user can adjust settings, control all of the projector's menu-based functions and even power the projector on and off. This user-friendly interface ensures a hassle-free experience. The location and design of the control panel make it easy to operate the projector by feel without the remote control, even when mounted on the ceiling.

The W4000i provides horizontal and vertical lens shift and zoom capabilities. These allow users to fine-tune the position of the projected image without physically moving the entire projector. This flexibility makes setting up the projector according to different room configurations or mounting preferences convenient.

The W4000i offers a wide array of connectivity options. Multiple HDMI ports, USB ports, and audio outputs provide ample opportunities to connect devices like gaming consoles, Blu-ray players, and sound systems. This versatility allows for the seamless integration of different multimedia components, enhancing the viewing experience.

The W4000i ventilation design helps keep the projector from overheating during extended use. The W4000i/HT4550i also incorporates noise control mechanisms, ensuring minimal fan noise and minimizing distractions during your viewing sessions.

The W4000i comes with two HDMI 2.0 ports, with one of the connections supporting Enhanced Audio Return Channel (eARC) functionality. Two USB Type-A connections support data and media transfer as well as power. Please see my chart below for a complete listing of all ports.



Benq Ht4550I Projector Lens - Projector Reviews - Image

The BenQ W4000i lens is made up of a high-precision 10-element 6-group lens array that fits perfectly to ensure the image stays clear and sharp from corner to corner. As is typical for projectors with both a focus and zoom wheel in the same space, manually adjusting the zoom to match the focus is simple by using the controls directly above the lens housing. The image looks great once the focus is dialed in. This is the best focus uniformity in a projector under $3,000.

Benq Ht4550I Throw Ratio Chart - Projector Reviews - Image

The lens on this projector is an F/# 1.8 - 2.25 mm, f 17.02 (Wide)~22.21(Tele). This projector's shorter throw distance is great for small spaces because it can project a big picture even if you don't have much room. You can make a 100-inch screen by placing the projector just 8.2 feet away.

However, for those who want to mount the W4000i in the back of the room might desire a little more zoom range. For example, the projector in Philip Jones' media room needs to be positioned on a shelf that is 14 feet from his 120" screen, which is about a foot too far away. 

You can use the lens shift feature if you need to adjust the picture to align perfectly with the screen. The W4000i also includes optical lens shift of Vertical 0%-60% (@ H 0%) Horizontal ±15% Max. (@ V 20.9%).  This lets you move the picture up and down and from side to side without losing quality.

BenQ projectors have menus that are easy to use and understand. The menus are organized in a way that makes sense, so you can find what you're looking for without any trouble. Navigating through the menus is simple and straightforward, so you can quickly adjust settings and explore different options. If you need help or explanations, the menus provide on-screen guidance to make things easier.

You can customize the projector settings to your liking, whether the brightness, color, or other aspects. The menus offer quick access to important functions, so you can easily switch inputs or change the picture mode. With BenQ projectors, the menus are designed to be user-friendly and make getting the best performance from your projector a breeze.

Like other BenQ projectors I have recently reviewed, this unit works on two different menu systems. The first is the BenQ projector menu, allowing users to control most projector features. The second is the Android TV interface. This is a hybrid menu system, but I prefer a more integrated system built around Android if the OS is part of the projector operation.



BenQ has loaded the W4000i with a ton of technology designed to improve the projector’s picture quality manually and automatically. The W4000i is fully configurable with all the controls and adjustments typically found on a professional projector for detailed calibration. Projector Reviews highly recommend a professional calibration to get the best performance from any projector. Calibrating the projector ensures users get the best performance possible for their screen and environment. Professional calibration opens access to the projector's ISF modes. If professional calibration is within your budget, do it by all means. But…

The BenQ W4000i factory calibration is excellent. I can't think of another projector in the W4000i's class and price point that performs as well as it does out-of-the-box. I'm not claiming it is perfectly calibrated, but it is so good that most users will square the projector, focus it, and be done with it. BenQ has included the usual suspects of preset picture modes. I'll go into these in more detail in the brightness section below.

BenQ has included a lot of video enhancement technology on the W4000i, an impressive new option falling somewhere between "Turn it on and forget it" and "Professional calibration.". These calibration settings are the BenQ Color Enhancer, Flesh Tone Smart Hue Adjustment, and Local Contrast Enhancer, which I find most interesting as it uses a custom BenQ algorithm to divide every scene into multiple zones and adjust gamma for each zone independently. The 4k Pixel Enhancer works like an advanced Photoshop sharpening tool but for video.

Once I got the projector set up and running, one of the first things I noticed about the BenQ W4000i was its ability to produce what I can only describe as one of the best out-of-the-box pictures I've seen from a projector in its class. I expected a similar performance to the company's X3000i 4LED gaming projector, but I was wrong. Click on the link to see my colleague Kam Valentine's full review of that projector.

This projector provides excellent color reproduction thanks to the advanced 4LED light source, a new DLP imager, and top-notch factory calibration. The W4000i's wide color gamut covers a broad range of colors, allowing for more accurate and lifelike visuals. No matter what I threw at it, the W4000i took it and turned it into a stunning on-screen image. Skintones, HD Upscaling, I even threw a DVD at it, and the picture looked halfway decent on my 100-inch screen.

The FILMMAKER preset picture mode is the best overall setting if you have a room with moderate control over ambient light sources. BenQ recommends this mode when playing 1080p SDR movies. You can see examples in the screen captures in the slideshow above from The Last Action Hero and Heat. These are not new movies by any stretch of the imagination, but the W4000i shows them at their best in FILMMAKER mode, where the projector can reproduce 100% Rec.709 color accuracy and can provide 110" at 48 nits (14fL) which are typically used in controlled dark spaces like movie theaters.

Like all Home Theater projectors, Philip Jones took the time to calibrate the W4000i. Since your room and screen material significantly impact the overall picture, we don't recommend using someone else's calibration adjustments. If your room is brighter/darker or your walls are a different color, your settings would probably be different. Also, the color characteristics of different individual projectors can vary. Therefore copying someone else's results can actually be detrimental to the picture quality rather than improving it. However, I am including Philip’s specific room before and after calibration results.

If you want to make BRIGHTNESS, CONTRAST, and SHARPNESS adjustments to optimize your projector for your room, several free test patterns are available on Murideo’s website and YouTube channel. Check out our YouTube video on utilizing several of these test patterns called Optimize The Image of a Projector or TV Using Free Murideo Test Patterns. Murideo also has written instructions located under the resource section of its website. We use Portrait Displays Calman color calibration software to test the projector's color accuracy.

Pre-Calibration Color Tracking and Grayscale

BenQ-W4000i-Calibration-Pre-Results - Projector Reviews - Image

While the color reproduction was great, we calibrated the USER1 mode for SDR viewing in a room with low ambient light. The measured color temperature of 6589K was close to our D65 (6500K) target. The projector's black level and shadow detail were better than most home theater projectors. The pre-cal Gamma measured around 2.1, which is slightly higher than my target of 2.2.

The W4000i white balance out of the box was outstanding, with an average Delta E under 2. This is better than most competitors’ projectors that we have measured.  The projector’s tracking was also good, with a Delta E under 4.

  • Picture Mode: User 
  • Color Temperature: 6589K
  • Gamma: 2.1
  • Average Grayscale dE: 1.6
  • Average Color Tracking dE: 3.8

Post-Calibration Color Tracking and Grayscale

BenQ-W4000i-Calibration-Post-Results - Projector Reviews - Image

I left the COLOR TEMP to the default of Normal. To produce better grayscale (RGB Balance), I increased the RED GAIN slightly, which resulted in outstanding results. After this adjustment, the measured color temperature was closer to my D65 (6500k) target. The W4000I includes 10pt ADVANCED COLOR TEMPERATURE TUNING, but there was no reason the utilize it.  

To achieve my Gamma target of 2.2, we set the GAMMA SELECTION to 2.2 and reduced the BRIGHTNESS slightly. While the W4000i color tracking is good, BenQ includes CMS adjustments which we used to finetune projector’s the color tracking further.

  • Picture Mode: User
  • Color Temperature: 6535K
  • Gamma: 2.19
  • Average Grayscale dE: 0.7
  • Average Color Tracking dE: 0.63

Delta E, as a measure of grayscale/color accuracy of 3 and under, is considered 'Excellent' and imperceptible by the human eye. The W4000i white balance out of the box was outstanding, with an average deltaE under 2. This measurement is better than several projectors we have reviewed, even after those units had been calibrated.  The color tracking out of the box was just 3.8, which is better than many projectors costing significantly more. Utilizing the precise CMS adjustments, we reduced the average Color Tracking Delta E to less than one which is awesome.

HDR Grayscale Measurement Before and After

BenQ-W4000i-Calibration-HDR-Pre-Post-Results - Projector Reviews - Image

In addition to the five SDR picture presets, the W4000i includes several HDR modes, which are HDR10, HDR10+, HLG, and FILMMAKER (HDR) MODE.

While both HDR10 and FILMMAKER modes delivered a good HDR picture, we thought FILMMAKER MODE was the more accurate.

When watching HDR, we noticed a slightly cool greenish hue on my sample unit when viewing a multi-step grayscale test pattern or watching brighter content.

This overemphasis on Green/Blue can be seen in the pre-calibration HDR measurements. However, quickly adjusting the 2Pt grayscale settings produced a good RGB balance (Grayscale).

When the W4000i projector’s color filter is engaged, it can reproduce 100% of the DCI-P3 color gamut at the expense of some brightness. The projector’s DCI-P3 color coverage is 1.3X wider than Rec. 709, which is especially important for red and green tones found in HDR content.

We have always been impressed with the color accuracy of BenQ home theater projectors. The picture quality of units like the HT3550i easily rivaled projectors that cost 2-3 times more. 

Since the W4000i is the successor of the HT3550i, we had high expectations, and the unit did not disappoint. As expected, the W4000i color reproduction was outstanding.

BenQ is focused on accurate color reproduction, and our measurements show it. The white balance of every W4000i is color calibrated at the factory, and each unit ships with a Cinematic Color factory calibration report.

FILMMAKER Mode is adjusted to maximize color when viewing 100% Rec.709 making it the best option when viewing SDR material, and white USER Mode is adjusted to maximize 100% DCI-P3 color found in HDR content.

BenQ's factory calibration results in out-of-the-box color accuracy that few home theater projectors can match.

According to the manufacturer, the BenQ W4000i projector produces 3,200 ANSI lumens of brightness. To see how bright a measurement I could get, I used the USER -1 picture mode and set the 4LED light source power rating to NORMAL, the highest setting. At wide zoom, the BenQ W4000i produced a brightness of 3,470 ANSI lumens. This exceeds the projector's rated brightness, meaning it lives up to its claim of being a bright projector. For the other modes available on the W4000i, I've compiled the results of my measurements below for your reference.

The BenQ W4000i projector displays impressive black levels. While newer SXRD and DILA projectors may have even deeper blacks, the BenQ W4000i comes closer than any other DLP projector in its class, especially considering its price. When comparing it to other BenQ projectors like the X3000i and the GP500, the W4000i surpasses them in terms of performance.

I've seen many projectors that sometimes sacrifice realistic image quality to maintain contrast ratios. However, the W4000i avoids this by combining BenQ HDR-PRO technology, the 4LED light source, and customized dynamic black software technology. Together, these technologies adjust light levels and optimize contrast in real-time, ensuring details are visible in dark shadows while preventing washout in bright scenes.

Another new feature that improves this projector's black-level performance is BenQ's Local Contrast Enhancer. LCE uses an advanced algorithm developed by BenQ that boosts contrast specifically for 4K HDR movies. LCE analyzes the brightness of different areas within the picture and adjusts the gamma independently for each zone. This preserves subtle details in dark and bright areas, enhancing the depth of the 4K HDR image. When Local Contrast Enhancer is enabled in HDR mode, the W4000i maintains more details in bright and dark areas, resulting in a richer and more realistic image.

The proof is in the slideshow above.



The single treVolo 5-watt chamber speaker produces some big sound for a mono speaker. It gets loud without distortion and can tune the audio settings with User Sound EQ. The W4000i's audio offers the following presets: Cinema, Music, Game, Sports, and User. In addition, the User audio mode allows the personalization of the sound settings via the User Sound EQ. It seems rather silly to offer sound modes for a mono speaker, but the equalization change makes a difference in the sound quality.

One of the most disappointing things about this projector is that BenQ didn't even try to put in a stereo sound system to match the video performance of the W4000i. It's not like BenQ hasn't already developed treVolo-tuned stereo sound systems and offered them a wide range of projectors, from the GP500 and the x1300i to the x3000i. How hard or expensive would it have been for BenQ to add a better onboard "stereo" speaker system with a simulated surround system to this amazing projector?

The BenQ W4000i's HDMI 2.0 port supports eARC, which enables higher-quality audio to be sent from the projector to an external audio device such as a soundbar or home theater audio system.


As in movie theaters, 3D projectors allow you to be fully immersed in a three-dimensional experience. 3D projectors for home theater enable the user to play 3D games and watch compatible 3D movies. While 3D content is no longer taking the world of movies and gaming by storm, it is still available. BenQ has decided to recreate your home entertainment with the combination of industry-leading 3D technologies.

The BenQ HT4550I features a 3D function that allows you to enjoy 3D movies, videos, sporting events, and games more realistically by adding depth to the image when wearing a pair of optional, compatible 3D glasses.


The W4000i is not the fastest gaming projector BenQ makes, but it comes very close. The W4000i supports a 17.9 ms input lag at 1080P 60 Hz, 17.9 ms at 4K 60 Hz, 21 ms at 1080p 120 Hz), and 8.7 ms at 1080P 240 Hz. These are professional performance specifications.

I am not a professional gamer, but I own a PlayStation and an X-Box console, and I love playing first-person shooters until I get sick, which sadly is in about ten minutes. But gaming on the W4000i was great for those ten minutes. Yes, gaming on a projector's giant screen is a lot of fun, but when I say great, I'm talking about not being bogged down by input lag. Not once did I find myself taken out of the game by a delay between pushing a button and seeing the corresponding action on-screen.

I was immersed in the game for a glorious ten minutes as I repeatedly died, not because of lag but because as much as I love gaming I'm bad at it. The good news is that this BenQ projector is fantastic for gaming!


The fan noise produced by W4000i is a little less than with other BenQ 4LED projectors I've reviewed. The BenQ W4000i produces 32dB in Normal mode and 28dB in Eco Mode. I never found the fan noise from the W4000i to be an issue or distracting especially in a typical home theater setup, where that projector would be ceiling mounted, I don’t think the fan noise would be noticeable. In my lab it isn't distracting, especially when the Light Mode is set to ECO. The published noise spec for NORMAL lamp mode is actually about 2dB higher than some lamp-based BenQ projectors like the TK850i. This surprises me but does not change my experience that the projector is as good as other similarly specced BenQ projectors.

The W4000i ,and its twin brother the HT4550i, displays a fantastic image out of the box for many reasons. First, the image is bright, measuring about 3,470 ANSI lumens based on my testing. This is primarily due to BenQ's continued advancements in boosting LED performance. Compared to a traditional 3LED light engine, this BenQ 4LED adds an additional blue LED that boosts the projector's overall brightness. This sounds similar to some laser-based light sources adding an additional blue laser diode, and this is true. However, there are some big differences. This new 4LED system does not introduce any specular artifacts that can often be found in RGB or dual blue laser light sources. The W4000i's engine uses no color wheels, so it is smaller, which reduces the overall size and weight of this new projector. LEDs should run much cooler than lamps or laser-based projectors, but this LED projector is about on par with the other BenQ projectors I've reviewed.

Out-of-the-box, this projector is nearly perfect with my only complaint being that the image leans a little toward greenish blues tones. BenQ has really made sure that the factory calibration on the W4000i is very good. BenQ also realizes that not every person has the ability to control the lighting in their room completely. For that reason, BenQ's new 4LED light source works incredibly well in spaces that always have some uncontrolled ambient light. This is a projector that functions incredibly well for lights on viewing.

The video quality of the BenQ W4000i is already good right out of the box. However, you can make significant changes to the on-screen image by adjusting settings such as Picture Mode, Light Source, and Color Temperature Tuning. For instance, I switched the Light Source mode from SmartEco to Normal and experimented with different Picture Modes like FILMMAKER and USER to find the best image for my viewing room. Using the User mode, I fine-tuned the HT4550i image to match my specific viewing environment.

The W4000i/HT4550i deliver class leading picture quality

The BenQ W4000i stands out from lower-priced projectors with its advanced color adjustment settings. Unlike many other projectors in its price range, the W4000i offers a wide range of adjustments to fine-tune the color and image quality. Within the projector's Advanced Color Settings menu, you can adjust various image parameters such as gamma, color temperature tuning, and HDR brightness. The projector offers an extensive Color Management System (CMS) to adjust the image further. These comprehensive color adjustments and an 11-point white balance control make it easier for users to tune the projector according to their preferences resulting in a more accurate and satisfying viewing experience.

The W4000i does an excellent job of upscaling content. Whether it's 1080p videos or sports broadcasts in 720p, even a good quality DVD looked good on the W4000i. The W4000i delivered sharp and detailed images without any issues. As mentioned, the W4000i uses a new 0.66" DMD Texas Instruments (TI) DLP chipset to achieve its 4K (3,840 x 2,160) displayed resolution. Unlike the smaller DLP imagers, this new DMD only needs to shift half as much to display a 4K image.

The BenQ SMARTECO mode automatically adjusts lamp brightness based on projected content. This mode enhances brightness and contrast, resulting in improved picture quality. SmartEco Technology enhances the contrast ratio, providing clearer text and more defined subtle details.

The W4000i is also full HD 3D-ready, allowing you to enjoy 3D movies, videos, sporting events, and games with enhanced depth when wearing compatible 3D glasses. Even though BenQ is marketing the W4000i as a home theater projector, this projector will be used in non-traditional ways. Its short throw functionality, small size, weight, and brightness make this projector usable as part of a home golf simulator.

Overall, the BenQ W4000i/HT4550i delivers impressive video quality and offers a range of features and settings to enhance your home entertainment experience for movies, television, or gaming. Video/Movie enthusiast in the market for a home theater projector under $3000 should definitely consider the BenQ W4000i/HT4550i.  It is highly recommended.
