![]() ![]() Scott Lang’s all-black outfit shows up brilliantly against the shadowy rear of Hank Pym’s house. It’s particularly impressive during the burglary scene of Ant-man on Blu-ray. The detail is good and sharp, with a little help from the Ultra Detail filter, and little is lost in the bright or dark sections of the picture. The colours of the robots are vivid and the landscape looks natural as they chase the eponymous hero through the forests and out into the rocky terrain under the piercing turquoise sky. With this better-informed exposure, we get that bold, brassy feeling that 4K should deliver. Ultimately, while this isn't ideal, it is a price worth paying. The trade-off is that it’s easy to catch the Optoma adjusting the on-screen light levels each time the shot changes. ![]() Without it, the picture lacks some punch. Optoma’s Dynamic Black image processing helps make up for this by adjusting the brightness parameters in real time. HDR10 acts as a guide for the UHD42 for each scene, but it’s not enough for a budget machine such as this to really get the most out of its limited contrast ability. That means that they can’t benefit from the frame-by-frame contrast information delivered through Dolby Vision and HDR10+ metadata. Almost all home projectors will only support the HDR10 and sometimes the HLG HDR standards. ![]() To get that depth, you’ll need to use Optoma’s Dynamic Black setting and that comes with some performance costs. It’s a level of darkness far beyond what you get with the five-star Epson EH-TW7000 or the pricier, Award-winning Epson EH-7100. It’s a light-reflecting approach, rather than a transmissive one, and that allows for some excellent black depth as we watch the opening sequences of Cybertron with Bumblebee on 4K Blu-ray. While that’s normal for a projector at this price, it’s worth noting that Optoma has chosen to go with DLP rather than the 3LCD technology preferred by Epson. The reality is that HDR is hard to do on a projector.The Optoma UHD42 uses a 0.47in chip, which has a 1080p physical mirror matrix and uses four-phase pixel shifting to quadruple the resolution and create the full 4K, 8.3 million on-screen pixels. One of the pleasant surprises was that the UHD50X HDR Sim mode improved content in almost all cases, at least to my eye. The truth is, I wasn’t able to tell much of a difference between HDR content and Standard Dynamic Range (SDR) content at 4K. I’m not saying that HDR content looks terrible on the UHD50X. LCD devices can do things like local dimming, making a huge difference when watching content presented in HDR. 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. In addition, the UHD50X allows users to adjust the HDR tone mapping according to the video content or environment. Optoma’s HDR color mapping and tone mapping technology help optimize the projector to get the most out of HDR/HLG movies or games. When an HDR/HLG signal is detected, the projector automatically switches to HDR/HLG Display mode. With this projector, you can enjoy TV programs like World Cup games or Blue Planet at home with stunning HDR effects. Online video streaming platforms such as YouTube, Freeview Play, or DIRECTV all support HLG format. Hybrid Log-Gamma (HLG) is an HDR system developed explicitly for live broadcast television by the BBC and Japanese broadcaster, NHK. 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. 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. 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. I can hear you saying, “But Phil, Xbox and PS5 support HDMI 2.1.” You are correct. 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. Even then, a maximum input lag of 15.7ms at 240Hz is stunning. The ability to game at 240hz is currently limited to gaming on a PC featuring costly hardware. This is a fantastic performance specification, but there are some caveats.įor starters, there are no gaming consoles that support 240Hz. The Optoma UHD50X is listed as featuring a 240Hz refresh rate when its Enhanced Gaming mode is activated. ![]()
