Super-smooth and detailed images come naturally to the Optoma UHD42.

Clearly better, with 4K UHD resolution
With over eight million pixels, Ultra HD 4K resolution brings four times more detail than Full HD, delivering sharper, life-like images and richer colours. A further advantage of UHD 4K resolution is that, because the pixels are smaller, you can sit much closer to the screen. This makes the UHD42 ideal for rooms that previously might have been too small for a projector to work at its best.

Reveal hidden detail with HDR10 and HLG
Compatible with HDR10 video, the UHD42 lets you see far more detail and texture. HDR enhances the brightest and darkest sections of scenes – letting you see detail in what was previously a solid block of colour. It also makes the rest of the colour spectrum appear more natural, giving an even greater sense of ‘being there’. The UHD42 is also compatible with HLG (Hybrid Log-Gamma) – the high dynamic range developed for broadcasting.

Class-leading brightness for lights-on viewing
Boasting an outstanding brightness figure of 3400 ANSI Lumens, the UHD42 not only offers bright and vivid colours but is also able to be used in many lighting conditions. Even during daylight conditions with curtains or blinds open, the Optoma produces a watchable and detailed picture – thanks to its sensational brightness.

Colour – just as it should be
The UHD42 is capable of reproducing the Rec.709 colour gamut, the international HDTV standard to guarantee accurate reproduction of cinematic colour - exactly as the director intended. Enjoy watching films and TV shows and playing games with stunning colours in any environment.

Colour Management System (CMS)
Display accurate life-like colours to best match your viewing environment. This unique feature provides you with the flexibility to fine-tune the colour settings to the Rec. 709 standard for optimal precision.

Wall Colour Adjustment for optimised colour
Although a dedicated screen is always going to give the best results, the UHD42 offers Wall Colour Adjustment for when this isn’t possible. Six options let you adjust the image to suit blackboard, light yellow, light green, light blue, pink and grey walls.

Vertical lens shift
Simplify installation with vertical lens shift, which provides a wider range of projector placement possibilities. This makes it easier to position the projector in your room and enables a wider range of screen size options.

Gaming advantage
A trio of features make the UHD42 perfect for gaming. 240Hz smooth motion gives fluid motion and reduced delay – making fast-moving games a less nerve-racking experience. Game Mode optimises the projector’s contrast to produce vivid detail and maximum contrast – perfect for spotting the danger lurking in the shadows. With input lag reduced to 15.70ms, you can be assured lightning-fast response times.

Flexible connectivity, including twin HDMI sockets
Featuring twin HDMI sockets (one compatible with HDR), you can connect a UHD Blu-ray player and video streamer. For older sources, the UHD42 also comes with a VGA input – perfect for laptops and PCs. Multi-room connectivity is enhanced by an RS232 interface, plus there’s a 12v output for syncing with an electric screen. Audio is outputted via digital optical or analogue 3.5mm sockets.

USB power
Another great feature is the handy USB power output. This is used to power USB-powered smart devices, such as the Google’s Chromecast or a Roku TV stick. Plug Chromecast, or similar, in and you’ll have easy access to smart video and TV services without the need for any other device or lengthy connection cables.

Rated 5 out of 5 by from Brilliant picture, Controls and features I have been a user of Optoma projectors for years and they have always represented excellent value, picture quality and features, this one is no exception. We have a larger Optoma 4K projector in our den, but I wanted one for our Holiday Home and this one fitted the bill. Out of the box the picture quality is very good, but with some little tweaking, it became excellent. We have a 100” pull-up screen and from a distance of around 3.5 meters this projected delivers an edge to edge quality picture. The UHD42 copes well in subdued daylight well and at night you can have dimmed lights on without any major picture quality impact. However, two ALR screens are on my shopping list when the price becomes more affordable. So, if your looking for a quality 4K projector that doesn’t break the bank, add this one to your selection list. Lastly, a quick thank you to TOM B on the Richer Sounds online support team. He could not have been more helpful.

Rated 5 out of 5 by from Easy setup. Great picture Great buy. Arrived really quickly. Straight out of the box to setup was really easy. The quality of the picture is superb, slight manual adjustment and ready to watch movies play on console. I would definitely recommend this to anyone wanting big screen for not much outlay...

Rated 5 out of 5 by from Yep, just as i researched made the right choice Had old sony projector 720p 17 years, love the big screen. Lots if research done on the new tech these days, especially around cost vs performance. The guy at richer sounds confirmed I had good logic vs older devices or huge tvs. This does cover them all as described it would. Not laser, but not £3k. no interpolation, but not needed etc. Hrd10 but no "+".... Fine. The hdr sim it has really impressive on 1080p. Its Got all the right new gen options that coming our way. Even getting new 3d glasses for the gimmick value But why oh why deny a lens cover included, and put as an paid extra accessory... Seriously!!!

Rated 5 out of 5 by from Great staff - great products I bought kit for a home cinema from the York Branch - Dylan and his team were fantastic. Dealing with COVID, supply chain challenges, last minute changes to equipment were all dealt with in a timely, professional manner.

Rated 5 out of 5 by from A lot of support and advice available Richer sounds were happy to price match anything I found online if I could find it cheaper. They were available for support, advice and genuine recommendations it wasn’t just a sales pitch. Very helpful and friendly staff. I will definitely be buying from here again.

Rated 5 out of 5 by from Brilliant home projector, quiet and very bright I bought this just before Christmas 2020, it was a massive upgrade to my previous 720p projector. I have a home cinema setup that's dark, so I am running the projector in low brightness and eco-mode. The image quality is astonishing, better than going to the cinema.

Rated 5 out of 5 by from Great Experience of projector - beaut. Physical setup was easy, cable management a little trickier; one of the ports is HDMI 1.4, one is 2.0 - both are technically 4K capable, but the former only at 30hz, which is a little juddery, but, especially given I was planning to hook my PC up to it, made the mouse look ridiculous. After that, found that the junction box for my various HDMI inputs was not 2.0 rated, so it lost signal once something scaled up to full 4K before going into the projector - this took me a while to figure out, but none was the fault of the projector. Only writing for if it saves someone some trouble in the future... Only niggle is that the menu controls for the projector are faffy. The 'information' tab contains things you'd expect to be able to alter, but can't, so you spend some time trying to figure out how to access the options. Meanwhile the actual ways to alter these are in the other menu tabs, which scroll onto more than one page, which isn't immediately obvious. Image quality etc - all excellent. Quieter than previous projector, quieter than my PC, and really bright. Like, so bright I had to paint the wall it was going onto grey (this is supposedly the optimal colour anyway, but a somewhat funny problem to have). Richer Sounds service - brilliant. Ordered during lockdown, service was uninterrupted, spoke to people on the phone to query some bits and they were friendly, confident and knew all the answers. Delivery was speedy thereafter despite the covid disruptions and the guarantee certainly eases stress.

Rated 5 out of 5 by from Fantastic Bright picture, Great picture, worked well with Virgin TV box which didn’t work with my old Optoma 141x projector. Much quieter than the old one 2 . Super fast delivery but still waiting for guarantee paperwork :-)
