Optoma
GT2400HDR
Optoma's 2026 successor to the GT2100HDR — same DLP form factor with a refined 0.496:1 short-throw lens, 4,200 ISO lumens, 1080p resolution, HDR10/HLG, and laser phosphor light source. The +$200 premium over the GT2100HDR buys an incremental refresh, not a generational leap: same role in a build, slightly newer chassis, broader availability as Optoma phases the prior model out across retailers.

Who this is for
Honest match per persona.
Good for
- Cost-Effective Buyer
Best brightness-per-dollar in the budget tier now that GT2100HDR is being phased out — same 4,200-lumen laser short-throw at $1,299, with current-model retailer availability and warranty.
- Space-Constrained
0.496:1 fixed throw fills a 100" screen from 3.6 ft. Same tight-room geometry as the GT2100HDR with the assurance the model will stay carried by retailers for the next few years.
- Recreational Player
1080p but bright enough for daytime garage play; laser life makes it set-and-forget. The right pick if you're choosing the budget Optoma today rather than chasing GT2100HDR closeout stock.
Not for
- Performance Seeker
1080p not 4K; no dedicated golf color preset. Serious-practice builds belong on AK700ST or TK710STi.
- Showroom
Entry-tier housing and no zoom; reads as functional rather than featured. Showroom builds should look at LK936ST or BU53RG.
- Family Setup
If movies and gaming matter alongside golf, step up to 4K — TK710STi covers multi-use far better.
