240Hz/15.7ms INPUT LAG

The Optoma UHD50X is listed as featuring a 240Hz refresh rate when its Enhanced Gaming mode is activated. This is a fantastic performance specification, but there are some caveats.
For starters, there are no gaming consoles that support 240Hz. The ability to game at 240hz is currently limited to gaming on a PC featuring costly hardware. Even then, a maximum input lag of 15.7ms at 240Hz is stunning. If you’re wondering why this 240Hz gaming projector is limited to 1080P with Next Generation consoles, it’s the fault of the HDMI (High-Definition Multimedia Interface) ports on the UHD50X. I can hear you saying, “But Phil, Xbox and PS5 support HDMI 2.1.” You are correct. However, the HDMI ports on the UHD50X are 2.0 and 1.4, so realistically, 4K high-refresh gaming on a console will never be possible on this projector.
The PS5, Xbox Series S, and Xbox Series X Next Generation consoles, graphical powerhouses that they are (especially compared to previous-generation consoles), can easily render 1080P images at 120fps, which can be displayed on the UHD50X for an enhanced gaming experience.


The Optoma UHD50X incorporates an RGBWRGBW 8 segment color wheel, designed to achieve a more vivid color performance with 3,400 lumens of brightness. In addition, according to Optoma, their specialized color calibration and adjusting technologies allow the UHD50X to exceed HDTV Rec. 709 standards for truer, more accurate colors.


UHD50X supports HDR10 and HLG. High Dynamic Range (HDR) is a standard designed to display a higher dynamic range in video signals, showing the image with more brightness and color without losing any details. Hybrid Log-Gamma (HLG) is an HDR system developed explicitly for live broadcast television by the BBC and Japanese broadcaster, NHK. Online video streaming platforms such as YouTube, Freeview Play, or DIRECTV all support HLG format. With this projector, you can enjoy TV programs like World Cup games or Blue Planet at home with stunning HDR effects.

When an HDR/HLG signal is detected, the projector automatically switches to HDR/HLG Display mode. Optoma’s HDR color mapping and tone mapping technology help optimize the projector to get the most out of HDR/HLG movies or games. In addition, the UHD50X allows users to adjust the HDR tone mapping according to the video content or environment.

HDR is really tough to do on a video projector because it’s not as noticeable as on a Liquid-Crystal Display (LCD) or an Organic Light-Emitting Diodes (OLED) display. LCD devices can do things like local dimming, making a huge difference when watching content presented in HDR. I’m not saying that HDR content looks terrible on the UHD50X. Quite the contrary, it looks excellent. The truth is, I wasn’t able to tell much of a difference between HDR content and Standard Dynamic Range (SDR) content at 4K. One of the pleasant surprises was that the UHD50X HDR Sim mode improved content in almost all cases, at least to my eye. The reality is that HDR is hard to do on a projector.


Optoma provides 3D Display mode to resolve the issues related to variations in the brightness of 3D images due to overlapping signals and specialized lenses. When a 3D signal is received, the system directly switches to 3D mode to elevate image brightness and contrast.

The built-in ISF Display Mode allows your calibrator to save your calibrated day, night, and 3D mode settings for the ideal viewing experience.


DLP BrilliantColor Technology for Ultra-High-Performance (UHP) lamps is a technology that can achieve up to 50% improvement in brightness over traditional three-color solutions. In addition, DLP BrilliantColor technology offers up to six-color processing, enabling a wide color gamut and making it possible to produce over one billion colors.


Dynamic Black can accurately control light bulb output power and automatically change based on different image brightness. There’s no need to use an aperture ring to adjust for dark scenes. With the Auto Gain function, details are more pronounced, and you can achieve a nearly three times increase in contrast ratio. The UHD50X Dynamic Black technology is one of the key reasons that this projector can display 500,000:1 contrast. In addition, the Dynamic Black mode makes darker video content present with more depth. If you’re going to watch any serious movies or television shows, I highly recommend turning on this mode. Unfortunately, when Dynamic Black is engaged, there’s a noticeable increase in the HD50X fan noise, especially when the video transitions between whites and blacks. Typically, you would set the projector to Eco mode to mitigate some fan noise, but you can’t engage ECO mode when Dynamic Black is turned on.


The UHD50X is what Optoma calls a True 4K UHD projector. A Texas Instruments 4K UHD DLP Chipset, featuring a high-performance DMD, powers this projector. Incorporating TI’s XPR video processing technology is one of the significant advantages of this DMD technology. XPR provides fast switching allowing the UHD50X to display 8.3 million pixels (4x the number of pixels of 1080P). True 4K with fast switching XPR technology creates pixels horizontally and vertically in four ways to achieve 8.3M pixels on the screen, all faster than the human eye can see.


Optoma’s Color Lab simulations were carried out for gaming in different ambient light settings to calibrate and boost the details in the dark and develop the exclusive Game display mode. As a result, gamers will avoid getting stuck at a certain level, as they can find the gimmick hidden in the dark.


Projecting on any wall with Optoma’s six-color compensation is provided to suit different wall spaces in the home and avoid distortion of colors. As a result, even in the absence of a projection screen, images can be viewed on a wall space with the most accurate color gamut.
