BenQ LU9750 Performance, Installation Flexibility, and Reliability

The BenQ LU9750 is an ultra-bright 8,500 ANSI lumens professional projector compatible with interchangeable lenses (not included) that sells for $11,999 MSRP. The LU9750 has a manufacturer-rated DYNAMIC CONTRAST Ratio of 3,000,000:1 and a WUXGA (1,920×1,200 pixels) native resolution. BenQ lists image quality, installation flexibility, and long-term reliability as the three key benefits of the LU9750.

A BenQ BlueCore laser diode is at the heart of the LU9750 light engine providing a light-source life that ranges from a guaranteed 20,000 hours in NORMAL mode up to an estimated 70,000 hours in DIMMING mode.

The LU9750 combines 24/7 operation and 360-degree installation. It is compatible with nine optional electrical lenses, making this projector an excellent choice for use in large venues for both single and multi-projector configurations. The LU9750 is ideally suited for use at large venues like tradeshows, galleries, museum installations, and many more due to its placement and feature flexibility.

According to Futuresource, BenQ is the best-selling global projector brand powered by Texas Instruments DLP technology. BenQ professional projectors offer a wide range of professional installation solutions, including digital, laser, and interactive projectors designed for the enterprise, education, and corporate entertainment markets. 

This new BenQ projector is a purpose-built solution to the need BenQ identified for affordable premium-quality projectors. BenQ states that the LU9750 is designed using the company's decades-long legacy and expertise in creating great projectors to deliver high brightness, precise image accuracy, and long-lasting reliability with zero maintenance.

The laser phosphor-light source can reproduce 95% Rec.709 color gamut.

The LU9750 uses a 0.67-inch DLP image sensor made by Texas Instruments combined with laser/phosphor illumination. The 0.67-inch DLP Digital Micromirror Device (DMD) used in the LU9750 is a larger sensor than you would find in many consumer and even some professional DLP projectors. This larger sensor offers some significant advantages over smaller 0.47-inch DLP imagers, including that it is optimized for large format projectors. The 0.67-inch sensor's larger surface area is better at managing the high output from the projector's laser-light source. 

Larger sensors can display a sharper image than DLP projectors using a smaller imager, especially when projected onto a large screen. On a WUXGA (1,920 x 1,080 pixels) projector like the LU9750, the larger DMD provides a low refresh rate of 34 ms, excellent color, and improved contrast performance versus a similarly specced 0.47-inch DLP chip. 

The DLP device used in the LU9750 comprises over two million micromirrors that reflect the pure light of the laser-light source to the projector's phosphor and color wheels. With large format, high brightness projectors like the LU9750 heat is also transferred to the DLP imager. To keep the imager safe, Texas Instruments hermetically seals the DLP chip allowing it to resist heat for over 200,000 hours of 24/7 operation without experiencing any degradation and ensuring true-to-life colors and pristinely legible text for countless uses.

The LU9750 uses a BenQ BlueCore laser-light engine with one yellow phosphor and one RGBW color wheel. The laser phosphor-light source can reproduce 95% Rec.709 color gamut and lists a dynamic contrast ratio of 3,000,000:1. The BlueCore laser-light engine is maintenance-free and features IP5X certification. The LU9750 comes with four manufacturer preset modes to control the laser's light output for the venue the projector is being used.

Sets the projector's light source to maximum output, providing a guaranteed 20,000 hours of life. Turns down the projector cooling fan to reduce noise and lowers laser brightness to extend the light-source life to an estimated 30,000 hours. Lowers laser brightness more than ECO mode, which extends light-source life up to an estimated 70,000 hours. Manually adjusts laser brightness by 1% increments between 20% to 100%.

The LU9750 offers professional features such as 360-degree Placement, Full Lens Shift, Electronic Zoom, and Focus to reduce installation complexity. BenQ also provides the ability to perform advanced adjustments such as Edge Blending and Warping in professional environments where multiple projectors are used to create one giant image. This projector also supports horizontal and vertical stacking.

BenQ exclusive white balance adjustments can reduce white balance variables between images projected from different projectors to such a low level that most people cannot see any difference. This reduction of variables allows for seamless and accurate picture quality without disruptive discrepancies and saves time adjusting color when installing projectors.

BenQ's LU9750 projector is compatible with multiple optional powered lenses designed to maximize throw ratio coverage. Nine (9) Japanese-made interchangeable lenses feature all-glass optics designed to eliminate chromatic aberration and color flare, provide the best-displayed image quality, and maximize installation options and projection layouts. All these are done with one quick one-button release, making changing this projector's lenses simple and secure.

The BenQ LU9750 is 3D-capable, accepting content from multiple source types. The projector is compatible with 3D Blu-ray players, 3D broadcasting, and 3D-capable game consoles. But the newest demand for this technology is in the education sector. They will be one of the largest consumers of 3D projectors in the next few years because 3D projectors help increase classroom engagement and knowledge retention. These projectors can be used in technical disciplines like design, engineering, and other specialized trades. In my opinion, this is the future of 3D projection.
