GT2000HDR vs GT2400HDR

Both are 1080p laser short-throws with a fixed 0.496 lens, so both put a 100-inch image up from about 3.6 ft — the same tight-room geometry. The GT2000HDR is under $1,200 at every retailer we list; the GT2400HDR is $1,299 at Amazon, Indoor Golf Outlet and B&H.

Brightness is the main gap: Optoma rates the GT2400HDR at 4,200 ISO lumens and the GT2000HDR at 3,500 ANSI lumens. The two standards are not measured identically, so read that as noticeably brighter rather than exactly 700 lumens. It matters in a garage with daylight leaking in, and much less in a dark basement.

Past brightness, the spec sheets are close. Both use Optoma's 30,000-hour DuraCore laser, both carry an IP6X dust rating, both take HDR10 and HLG, and Optoma lists input lag of 8.6ms for the GT2000HDR and 8.4ms for the GT2400HDR at 1080p/120Hz. The GT2400HDR is the one Optoma markets with a Golf Sim picture mode; the GT2000HDR has no golf preset. The GT2400HDR is also the newer model and will stay in retailers' catalogs longer.

For a dim room the GT2000HDR is the better value. For a bright room, or if you want the golf preset and the current model's support runway, the roughly $200 more for the GT2400HDR is well spent. One more to price before you buy the GT2000HDR: the GT2300HDR is $1,099 at Indoor Golf Outlet and Amazon, about what the GT2000HDR costs now, with the GT2400HDR's cabinet and lens at 3,600 ISO lumens.
