A powerful combination of features and peformance

We reviewed the other LG model in this series, the LG ProBeam BU60PST, and were impressed by the projector's picture quality and feature set. Check out our review by clicking the link.

As a leading manufacturer of flat-panel TVs, LG understands that some customers are looking for a bigger and more immersive image than even the largest OLED or LCD TV can provide. The BU53PST is part of the LG ProBeam projector lineup. The ProBeam series of projectors are designed to make front projection more accessible and appealing to a broader range of business and education professionals.

DLP Technology Inside
DLP delivers proven quality and reliability

Utilizing a Texas Instruments DLP (.47″ DMD) with XPR technology, the ProBeam BU53PST displays 4K (3,840 x 2,160) UHD resolution.

The ProBeam BU53PST light engine is enclosed, preventing dust particles from settling inside the sealed, laser-projected light path and obstructing the projected image.

The ProBeam BU53PST utilizes a laser-phosphor light source that provides a manufacturer-rated 5,000 ANSI lumens of brightness designed to produce sharp, clear images in venues with active external light sources. A light output rating of 5,000 lumens is bright enough to be utilized in many business, hospital, museum, and education environments where ambient light is present. LG uses a high-output laser diode in the BU53PST rated to provide up to 20,000 hours of near-maintenance-free operation. Providing 20,000 hours of operation is equivalent to playing videos on this projector for eight hours daily, which translates to the laser diode lasting for seven years!

The combination of laser phosphor illumination and DLP imaging ensures excellent performance and durability. In addition, routine lamp replacements and maintenance are not needed so that the ProBeam BU53PST can be placed in difficult-to-reach locations such as creative museum displays or high-ceiling installations in auditoriums.

The ProBeam BU53PST is a short-throw projector allowing it to sit close to the screen. The projector offers a 1.2x manual zoom lens along with horizontal and vertical Lens Shift, which is rare on DLP projectors of this size and price point. Combined with the 12-point Warping function, these features reduce image distortion and allow precise alignment with the screen.

While LG ProBeam models do not have all the smart features found in the CineBeam products, the ProBeam BU53PST does have several notable features that enhance connectivity and productivity.

The BU53PST features a range of built-in preset modes, including seven preset video modes and six preset audio modes. These preset modes help you get the most from the projector within different venues. 

The BU53PST features two built-in speakers and an HDMI Audio Return Channel (ARC) with a simple connection to soundbars to offer an immersive experience. The projector also includes Bluetooth so you can play audio from a device such as a smartphone through the projector's internal speaker or a connected audio system. You also can connect Bluetooth headphones or speakers to play sound from the projector.

Advanced wireless networking capabilities provide operational flexibility

The BU53PST offers monitoring and control via a network supporting 3rd-party solutions from Crestron, Control4, and Savant, as well as supporting RS232C. The BU53PST also provides HDBaseT compatibility allowing a single CAT6 cable to carry 4K signals hundreds of feet to the ProBeam BU53PST projector.

The BU53PST is compatible with HDR10 content and is also one of a limited number of projectors capable of Dynamic HDR Tone Mapping. This feature, developed for LG's consumer CineBeam projectors, automatically adjusts the projector's tone mapping curves based on the scene playing to optimize the unit's HDR performance.

The BU53PST's combination of high brightness, low maintenance, and good picture quality make it a compelling alternative to a large flat-panel TV in almost any professional space. LG says the BU53PST fits as easily in the living room as in the meeting room.

It seems like only yesterday I was reviewing the Optoma UHD50X projector. When you look at the UHD35 on paper or even at the projector out of the box, you would be tempted to think that Optoma just slapped the same components into an almost identical box. Maybe they did, but the performance of this projector is not a carbon copy of the UHD50X. The internal components may be identical, but the picture is different. Different good or different bad? You are going to have to read on... Like its older brother, the UHD35 is a gaming projector, and, like the UHD50X, it shares a lot of amazing specifications and technology.

As a gaming projector, the Optoma UHD35 core components operate at much higher levels of performance than a standard projector. Some of the key differences include the projector’s refresh rate, low input lag, and the ability to produce superior contrast. This level of performance provides the gamer with the ability to identify objects in the extreme ranges of bright and dark or to keep from getting killed by another player. Projectors like the UHD35 are optimized to work better with gaming consoles and high-performance gaming computers. This better performance is a result of being able to display a higher dynamic range of colors, higher resolution, and much faster refresh rates. Sound quality is also critical and in this review, I’ll let you know how the UHD35 does on all those fronts. Put simply, gaming projectors do more than offer a bigger and better television screen, they offer performance at a level that, until recently, was only available by owning a high-performance gaming display.

Overview

Optoma UHD35 Gaming Projector

Optoma says that the UHD35 is the next generation of 4K UHD cinema gaming projectors. I paraphrase.

As with its previous UHD projector offerings, Optoma is focusing heavily on both the input lag rating of the Optoma UHD35 and its 4K cinema performance. When it comes to gaming, Optoma publishes a specification of 4.2ms vs the UHD50X input lag of 15.7 milliseconds in Advanced Gaming mode. This lamp-based DLP projector uses a Texas Instruments .47 DMD imager with TI’s proven pixel-shifting technology. This technology allows the Optoma projector to display true 4K resolution onscreen by using a single mirror to create multiple pixels of data, faster than the human eye can see.

Optoma says they want their users to be able to immerse themselves in a world of Ultra HD gaming, live sports, TV shows, and movies. The UHD35, like its predecessors, is designed to deliver impressive cinema-quality images, all with 3,600 Lumens of brightness. That’s the manufacturer’s claim. Since I don’t have the ability in my lab to measure input lag, my editor, Phil Jones will be testing this feature and adding an editor's addendum to this review. Like the UHD50X, the UHD35 offers a refresh rate of 240Hz with the exact same limitations. The UHD35 can project images up to 300-inches and, at least on paper, should be quite a projector at its price point.

The UHD35 is packed with Optoma’s latest technology and features. It boasts High Dynamic Range (HDR) and Hybrid Log Gamma (HLG) compatibility, Full 3D, and two HDMI 2.0 ports.

Optoma UHD35 Gaming Projector

The Optoma UHD35 has a manufacturer Lumens rating of 3,600 ANSI Lumens, an increase of 200 over the UHD50X, and a contrast rating that is nearly double that of the UHD50X at 1,000,000:1. The UHD35 makes use of Optoma’s BrilliantColorTM technology and an 8 segment color wheel that Optoma says will produce, “the truest and most accurate colors,'' presumably in this class or price point. You better believe that we’re going to check it out. Finally, Optoma is touting the UHD35’s HDR 10 & HLG support, which the manufacturer claims will provide, “the brightest whites, deepest darks, and lifelike color.”

As always, my goal is to provide you with a good idea of how the Optoma UHD35 lives up to the manufacturer’s claims, and if this projector is the right choice for your home entertainment/gaming needs. And away we go!
