In other words, expect 4K/60 to look better (sharper) on this projector, which isn't the case with You’ll struggle to tell the difference, though.I tested the projectors at three 4K refresh rates: 24, 30 and 60Hz, and as with the BenQ, the lines were darker and clearer with 60Hz on the Optoma. Built around Texas Instruments’ 0.47in DMD DLP chip, it’s optimised for 1080p but uses a technique called pixel shifting to create an image of multiple flashes that for all intents and purposes looks as if it’s the all-important 3840x2160 pixels – 4K resolution. Blame lies squarely with its long-throw lens, whose 1.5:1 throw ratio and paltry 1.1 zoom means you’ll struggle to project an image any smaller than 100 inches.įor all its quality, know that the UHD38 isn’t strictly speaking a natively 4K projector. However, Bright mode does add a noticeably green tinge.įor all its all-round image quality – save for those average black levels – the UHD38 isn’t the most flexible projector for the home. It’s searingly bright, if you want it to be, with its Bright mode’s 4,000 ANSI lumens suitable for use during, say, a summer afternoon, as long as there’s no sunlight on the screen or wall hosting the projection. A Gaming mode adds extra sparkle to games while movies on 4K Blu-ray convince if watched in Cinema mode. Colours are vibrant and well saturated from the UHD38’s eight-segment DLP colour wheel – enough to make colourful games really pop – though we’ve seen both more impactful HDR and better black levels. Images are crisp, finely detailed and plenty immersive. When it’s displaying 4K you’re seeing an image that’s just under 8.3 megapixels. In fact, the UHD38 delivers a likeable image whatever the source and resolution. Just as importantly, fast-action sequences during games and movies look fluid enough, camera pans don’t suffer from judder and there’s not a trace of that old DLP nasty – ‘rainbow effect’. ![]() These characteristics apply whatever presets are used, from Cinema through Gaming, Reference and Bright.Ī lot of this is show-off detail since most humans aren’t going to notice the fact that the UHD38 goes well below 40ms is enough to impress. In fact, if you’re playing a game that’s natively 4K/60Hz then the UHD38 delivers only a 16ms response time (still faster than most TVs) and doesn’t support 4K/120Hz. The UHD38’s headline feature – Enhanced Gaming Mode – impresses in its lag-free fluidity but doesn’t peak with 4K. Here’s a projector that’s optimised for gaming throughout, but still generally impresses across the board. There are plenty of other ins and outs VGA in, 3.5mm audio in and out, optical audio, a USB-A and a 12V trigger to hook-up to a motorised screen. However, while buyers of the UHD38 might be excited about its ‘Enhanced Gaming Mode’, its lack of HDMI 2.1 means it can’t support 4K/120Hz. On the rear is a brace of HDMI 2.0 inputs. ![]() ![]() It also lacks manual lens shift levers, which all projectors should always include the provision of some basic digital keystone correction controls is no substitute. Critically, the UHD38 has a 1.5:1 throw ratio so you need to place it about 3m from a 100-inch screen. There’s a manual focus ring around the lens while a lever behind it offers a paltry 1.1x zoom. Setup is simple, if lacking in flexibility. You likely won’t notice if you sit in front of the UHD38 – which you most probably will – though in a blackout room the resulting glowing blue light is distracting if it’s in your eye line. ![]() Easy to pick up and position, the rounded white plastic chassis is pleasant enough though there are a few airflow grilles that leak light. The UHD38 is reasonably compact, measuring just 315 x 270 x 118mm (12.4 x 10.63 x 4.65 inches) and weighing 3.98kg (8.77lbs). (Image credit: Future) Design and features
