Released 2024
Optoma
GT2100HDR
DuraCore laser short-throw with 4,200 ANSI lumens, 30,000-hour engine life, and IPX6-sealed body. The honest 2026 replacement for the discontinued GT1080HDR — laser longevity at a similar entry price. Note: being phased out by Optoma in favor of the GT2400HDR (which is the same form factor with similar specs); existing GT2100HDR stock may sell at discount before the swap completes.

Who this is for
Honest match per persona.
Good for
- Cost-Effective Buyer
Best brightness-per-dollar in the budget tier — laser, 4,200 lumens, 30k-hour engine, sealed body. Avoids the false economy of paying lamp prices in 2026.
- Space-Constrained
0.50 fixed throw fills a 10-ft screen from 5 ft — the right geometry for tight ceilings and shallow rooms.
- Recreational Player
1080p but bright enough for daytime garage play; set-and-forget laser life means no bulb planning.
Not for
- Performance Seeker
1080p (not 4K) and no Golf Mode color preset; serious practice deserves the AK700ST or TK710STi.
- Showroom
Entry-tier housing and no zoom; doesn't carry the showroom aesthetic or flexibility.
- Family Setup
If movies and gaming matter, step up to a 4K projector — TK710STi covers multi-use far better.
