Optoma hasn't just sliced the price of 4K projection, it's made 3D cool again

Brilliantly priced, a rock-solid performer and with just enough setup flexibility not to make installation a chore, Optoma's UHD51 certainly shakes up the home cinema projection market. 4K UHD has unapologetically relegated Full HD to the cheap seats, and offers a level of performance that would frankly have been unthinkable for the price, even a few months ago. It's well appointed, capable of extreme clarity and even makes 3D fun again.

This low-cost UHD projector uses an XPR (eXpanded Pixel Resolution) 0.47-inch DMD chip to produce 4K images. It’s a sharp performer, with a strong colour performance and low noise.

There are two HDMI inputs, as well as PC VGA and USB. There’s a fair amount of additional configuration on offer. Multiple gamma settings are available, and there’s variable colour gamut selection. A six-segment RGBRGB colour wheel claims to cover 100% of the BT.709 colour space.

Images are pin-sharp and colour accuracy is superb. Black level can be tweaked using the Dynamic Black setting. We preferred it Off, however some might like the denser blacks it produces. For the greatest contrast, keep the lamp setting on Bright.

In terms of setting up the projector, it was an absolute breeze.

This image was taken in daylight and I was really impressed with the quality.

The picture is insane.  The quality is unbelievable.  The depth in the blacks is brilliant – I wasn’t expecting that! And the brightness, the vividness and the detail is absolutely just crazy good!

But if you are in the market around £1500 mark then definitely consider the UHD51 and UHD51A because they are stunning. They are really great value for money.

I can highly, highly recommend these two projectors

Optoma UHD51 is an extremely well-equipped and exciting low cost projector with UHD resolution that would have been four times as expensive just a few years ago.

It is a low cost projector with reproduction technology best suited for HDTV and streaming material in a normal, non-dark room, like a living room.  

When it comes to colours, the UHD51 is impressive, achieving the HDTV color space exactly at Rec.709. Optoma claims to be able to produce 100% Rec.709 and 80% of the larger DCI-P3 biocolor space.

The UHD51 is honest and gives an unexpectedly fine color reproduction within the HDTV-colour space that is standard today on Blu-ray movies, HDTV broadcasts and most of that material which can be received streaming.

Star Wars: The Last Jedi, really punched through with the space-based scenes looking stunning. However, what really impressed was the final act sequence on Crait - the blood red on pristine white contrast as the speeders whipped up the surface of the planet was stunning and the colour depth provided by the UHD51 made this look better than even the cinema presentation.

Our short time with the UHD51 got us excited for the potential of 4K projectors. For £1499 you can't get more screen for your money - it's a bargain - and you won't be disappointed with shelling out that much cash for it.
