Game simulators and home entertainment have transformed from laggy, low-res projections to fully immersive experiences. Today’s gamers demand lifelike visuals, instant feedback, and razor-sharp detail. The Optoma 4K400STx answers the call. Designed for ultra-short throw angles and genuine 4K UHD output, it delivers desktop-window-sized images in your living room or gaming den. With a low input lag of under 16 ms, it keeps every button press in sync. Its HDR compatibility and Rec. 709 color coverage ensure accurate hues across all your favorite titles.

Whether you’re testing your aim in a first-person shooter, fine-tuning a racing sim, or hosting a movie marathon, the 4K400STx tracks every move with pristine accuracy. It doubles as a top-tier home theater projector, offering flexible input options and stellar image quality. Its whisper-quiet cooling system keeps fan noise out of your gameplay, and an adjustable zoom range lets you tweak screen size without shifting the unit.

With 4000 lumens of brightness and smart correction features, it thrives even in rooms where you can’t draw the curtains. That makes it perfect for multi-use setups, from esports training to family game nights. Dynamic Black technology automatically boosts contrast in dark scenes, revealing hidden details in shadows and giving you an edge in the gloomiest raid or horror title.

Immersive Visuals Fueled by Precision

Standard projectors often wash out under ambient light, but this model pumps out 4000 lumens of bright, clear imagery that holds up in well-lit spaces. You’ll see every detail, from glossy surfaces on game characters to fine lines in HUD displays. Plus, its HDR10 support and wide color gamut reproduce vibrant reds, deep blues, and lifelike greens across any game or film.

True 4K UHD resolution brings over 8.3 million pixels to life, reducing the grid-like effect you might spot on lower-res screens. You get richer textures, deeper colors, and a sense of depth that puts you inside the action. Combined with precise color calibration, you’ll enjoy consistent image fidelity game after game.

Thanks to four-corner image alignment and both vertical and horizontal keystone controls, you can position the projector almost anywhere and still end up with a square, even picture. No more awkward angles or wasted wall space. The intuitive control interface lets you save custom presets, so you can jump between gaming, movies, or simulations in a heartbeat.

Flip between your gaming console, PC, or streaming device in seconds using the two HDMI ports. A softly backlit remote keeps controls at your fingertips, even when the lights go down for late-night sessions.

Dominating the Competition

Models like the BenQ TK700STi, TK710STi, and AK700ST offer 4K short-throw projection, but they often cap out around 3000 lumens or lack robust calibration tools. You might get crisp resolution, but not the brightness or fine-tuning you need for varied lighting environments. And many lack a backlit remote for low-light use, meaning you might fumble menus mid-game.

The Optoma 4K400STx clears these hurdles with its 4000-lumen output, advanced image alignment, and uncompressed UHD clarity. Whether you’re logging marathon play sessions or hosting a film festival for friends, it delivers without compromise. Plus, its professional-grade components ensure long-term reliability, so you won’t face sudden lamp failures mid-tournament.
