BenQ LK936ST: Specs, Throw Distance & Alternatives
A 15.4 lb short-throw 4K laser projector built for installation. BenQ rates it at 5,100 ANSI lumens (ProjectorReviews measured 5,309 in Bright mode). It has vertical and horizontal lens shift and a 1.1x zoom, but no smart TV system or wireless networking.
Is the BenQ LK936ST right for you?
Good for
- Rooms with a lot of light: 5,100 ANSI lumens rated
- Flexible placement: ±60% vertical and ±23% horizontal lens shift with a 1.1x zoom
- Installed setups: two HDMI 2.0b ports, DisplayPort, HDBaseT and RS-232 control
- Soundbars and AV receivers: HDMI eARC and optical audio out
What to plan for
- No smart TV system and no wireless networking: add a streaming stick (the USB-A port supplies 2 A of power)
- BenQ’s input lag figures are ambiguous (it lists both 16.7 and 33.4 ms), so none is stated here
- Manual focus and manual zoom
- A single 10 W mono speaker
- At 15.4 lb it is an installation projector, not one to carry around
