OVERVIEW
According to Futuresource, BenQ is the top-selling projector brand globally that uses Texas Instruments DLP technology. BenQ offers a wide range of projectors for professional installations, including digital, laser, and interactive models for businesses, schools, and entertainment venues.
The BenQ LU9750 was built to meet the demand for affordable, high-quality projectors. BenQ says this model reflects its years of experience in making projectors, delivering high brightness, accurate images, and long-term reliability with zero maintenance.
The LU9750 uses a laser phosphor light source that can reproduce 95% of the Rec.709 color gamut.
It features a 0.67-inch DLP chip from Texas Instruments, which is larger than the 0.47-inch chips used in many other projectors. This larger chip is better suited for high-brightness, large-format projection. It handles heat more effectively and produces sharper images, especially on big screens.
The bigger DLP chip also offers a low refresh rate of 34 ms, better color accuracy, and improved contrast compared to smaller chips. It contains over two million micromirrors that reflect the laser light through a phosphor and color wheel to create the image.
To protect it from heat, the DLP chip is hermetically sealed. This helps it last over 200,000 hours of 24/7 use without degrading, ensuring sharp text and vibrant colors over time.
The BenQ LU9750 features a BlueCore laser-light engine that uses a yellow phosphor wheel and an RGBW color wheel. This setup delivers 95% Rec.709 color accuracy and a dynamic contrast ratio of 3,000,000:1. The engine is sealed and IP5X certified, so it’s dust-resistant and maintenance-free.
There are four preset light modes to match different environments and extend the projector’s life:
NORMAL – Maximum brightness, guaranteed 20,000 hours.
ECO – Lower brightness and fan noise, extends life to about 30,000 hours.
DIMMING – Even lower brightness, extends life to about 70,000 hours.
CUSTOM – Lets you manually adjust brightness from 20% to 100% in 1% steps.
The LU9750 includes advanced installation features like 360-degree placement, full lens shift, and motorized zoom and focus. It also supports edge blending and image warping, making it ideal for large multi-projector setups. Horizontal and vertical stacking are supported as well.
BenQ also offers unique white balance adjustment tools to ensure consistent image quality across multiple projectors—minimizing color differences that can distract viewers and saving setup time.
The LU9750 supports nine high-quality interchangeable lenses, made in Japan with all-glass optics. These lenses help reduce color distortion and ensure sharp, clear images. Swapping lenses is quick and secure with a one-button release system, giving you flexibility for different projection setups.

The BenQ LU9750 supports 3D content from a variety of sources, including 3D Blu-ray players, 3D broadcasts, and gaming consoles. One of the fastest-growing markets for 3D projectors is education. Schools and training centers are using 3D to boost student engagement and improve how well information is remembered—especially in technical fields like engineering, design, and trades. In my opinion, 3D projection will play a big role in the future of learning.
