Enhanced Gaming Mode
4 MS INPUT LAG, FASTEST IN THE LINEUP
Optoma's Enhanced Gaming Mode drops input lag to 4 ms, the fastest of any projector we ship. Your launch monitor's ball-flight data renders on screen with effectively zero perceived delay. Critical for accurate putting reads and immediate visual confirmation of every shot. Faster than competing 4K projectors at this tier by a wide margin.
True 4K UHD Resolution
4K DETAIL ON A 120-INCH SIM SCREEN
True 4K UHD (3840 x 2160) puts roughly four times the pixel count of a 1080p projector on the same screen. Course rendering, individual blades of grass, distinct tree lines, sharper ball-flight tracking. If you care about visual fidelity at sim-screen scale, 4K is the upgrade you feel.
Short-Throw 4K Is Rare
4K UHD FROM UNDER 5 FEET OF THROW
Most 4K projectors are long-throw and demand a deep room. The 4K400STx keeps a 0.5:1 short-throw ratio at 4K resolution, fitting 4K UHD into tight basements, garages, and low-ceiling builds where you'd otherwise be stuck at 1080p.
HDR10 And HLG Support
DYNAMIC RANGE ON FAIRWAY RENDERS
Both HDR10 and HLG support, deeper blacks, brighter highlights, accurate shadow detail. Combined with 4K UHD and 4,000 lumens, this is the picture quality tier that makes sim play feel cinematic. 16ms enhanced gaming mode keeps shot feedback real-time.
Easier Install Than You Think
MOUNT, PLUG, AND HIT IN UNDER AN HOUR
Most home sim owners install the Optoma 4K400STx themselves in 30-60 minutes. Mount it, run one HDMI cable to your gaming PC, plug in power, dial keystone, that's it. If you've installed a ceiling fan or a TV mount before, this is easier. If you'd rather not DIY, our SimSquad team walks you through the install on a call.
What is the Optoma 4K400STx?
The Optoma 4K400STx is a true 4K UHD short-throw projector for home golf simulator rooms. 4,000 ANSI lumens, HDR10 and HLG support, 0.5:1 short throw, and 16ms gaming mode input lag. The 4K short-throw value pick in the Optoma lineup, similar tier to the UHZ35ST with a lamp-based engine instead of laser.
Why Choose the Optoma 4K400STx?
Honest framing: the 4K400STx and UHZ35ST are similar-tier 4K short-throws at similar price. The 4K400STx runs on a lamp (15K-hour life), the UHZ35ST runs on laser (longer life, no bulb swaps). If you'd rather pay nothing for ~15K hours of bulb life and accept eventual bulb cost, the 4K400STx is fine. If you want set-it-and-forget-it laser reliability, pick the UHZ35ST. Performance on screen is nearly identical, with one tip in the 4K400STx's favor: 4 ms input lag in Enhanced Gaming Mode vs the UHZ35ST's 4 ms (effectively tied, both class-leading).
