The MSS verdict

Why people buy

16.7 ms input lag in Game mode, instant swing-to-screen
0.69-0.83:1 short throw fits tight golf sim rooms
3,000 ANSI lumens holds up on impact screens with lights on
1.2x zoom gives mounting wiggle room at a $949 price

Trade-offs

Lamp-based: 4,000 hr normal mode, ~$136 module swaps
No lens shift, mount placement must be exact
33 dB normal-mode fan noise is noticeable
1080p only, no HDR support
The fine print
Catalog's 10,000 hr lamp figure is the SmartEco rating; BenQ rates normal mode at 4,000 hrs. Budget ~$136 per OEM lamp module (5J.JGT05.001) over the projector's life.
