Description
The MW809STH is BenQ's short throw education projector for interactive whiteboard rooms. A 0.49:1 throw ratio puts a 70 to 120 inch image on the board from a short-arm wall mount, which keeps the teacher out of the beam and off the glare.
It produces 3,600 ANSI lumens at native WXGA (1280 x 800) with a 20,000:1 contrast ratio from a DLP engine, so text and spreadsheets stay readable with classroom lights on. BenQ's SmartEco lamp management extends light source life to 10,000 hours, and LampSave mode to 15,000 hours.
Interactivity is an option rather than a fitted feature: the PointWrite PW02 pen module and FingerTouch PT12 kit attach to the projector and turn the board surface into a touch surface. Connectivity is deliberately broad for an existing estate — two HDMI inputs, two D-sub inputs and a D-sub output, two audio inputs, a 10 W speaker, USB Type-A and Mini-B, and RS-232. The chassis is 296 x 239 x 120 mm and 2.6 kg.
Key features
Key Features • Advanced Dustproof Solution with Anti-dust Accumulation Components • SmartEco Power Saving Technology • 0.49 Short Throw Ratio • Designed for Education & IWB • Blu-ray Full HD 3D support • PointWrite Interactive Solution Compatible
Incorporating color wheel sensors with an ingenious anti-dust accumulation feature MW809ST prolongs optimal performance by rejecting dust which can accumulate on traditional sensors to block the IR signal and cause flickering abnormal colors or even shutdown.
Offering a big screen in short distance with a 0.49 short-throw ratio MW809ST eliminates distracting shadows and glare for students and teachers to engage and collaborate freely in front of the board.
MW809ST produces 3000 high ANSI lumen brightness and resolution for perfect projection performance with crisp images and sharp text even in bright lecture room. High brightness provides clear content under high ambient lighting allowing lights to be kept on during classes for note taking and interactive collaboration.
BenQ education projectors offer a range of resolutions and projected image sizes to meet diverse classroom needs. Featuring crisp image quality up to 120 inches our ultra-short throw education projectors deliver increased classroom versatility at reduced costs.
With sealed design that protects the DLP chip from dust-induced image degradation and the industrial-grade durability of DLP projection technology BenQ education projectors are capable of maintaining long-lasting picture quality by eliminating color decay. Unlike non-DLP projectors BenQ education projectors deliver premium picture quality equivalent to the result from brand new projectors after lamp replacement.
BenQ DLP projectors feature class-leading high fill factor minimizing black borders around each pixel to eliminate the dreaded “screen door effect” commonly observed in non-DLP projectors. BenQ education projectors produce superior definition and clarity in small-size text and fine details for beautifully rendered images instead of pixelated graphics.

Frequently asked questions
How bright is the MW809STH and where is it best used?

How close to the screen can the MW809STH be installed?
Very close — it has a short 0.49 throw ratio. Throw distance is roughly the throw ratio multiplied by the image width, so for a 100-inch 16:10 image (about 2.15m wide) that works out to only around 1.05m from the screen, ideal for tight classroom spaces.
