Optoma 4K comparison of the magnified area of a projected image

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

HDR Compatible
Capable of receiving and displaying HDR meta data, Optoma HDR compatible projectors allow you to see far more detail and texture. Objects look more solid and life like and the extra detail creates a greater sense of depth. It’s like looking through a window.

Colour Management System (CMS)

Passion Home Cinema
“The UHD40 succeeds to reproduce every single details of our UHD pattern with XPR treatment of 4K simulation. I really like the manufacturing quality, the quiet operation and the colour accuracy. There is also great sharpness of the image which is great”

Home Cinema Choice
“As hoped for, the UHD40 delivers excellent levels of detail and sharpness with my Jumanji: Welcome to the Jungle 4K Blu-ray.”
“Motion looks impressively natural too suffering minimal judder and no significant blurring even during the high octane helicopter chase sequence.”
In summary for its group test, Home Cinema Choice awards UHD40 the group winner:
“Sneaking into first place by a nose is the pricier Optoma UHD40. Its extra setup flexibility is a major draw amidst these relatively casual projectors. Most importantly, its extreme sharpness and uniquely high brightness help it to unearth that little bit more what the 4K HDR format is all about.”

What Hi Fi
The Optoma UHD40 is a projector that brings top-tier technology to a lower price bracket – and implements it very well indeed. It’s no understatement to say that rival manufacturers are going to have a hard time trumping this performance.
Colours are vivid, yet realistic; there’s lashings of detail; and motion remains silky smooth. There’s no other way to say it: the Optoma UHD40 is a simply outstanding budget projector.
Five stars

Trusted Reviews
So rich in detail, texture and clarity are the UHD40’s pictures that it’s almost impossible to reconcile them with the projector’s £1599 price. The UHD40 delivers this remarkable detail without exaggerating grain or causing stressy edges, either.
The UHD40 also manages to deliver a greater brightness lift with HDR sources than I’d have expected from such an affordable projector.
There’s no blockiness, striping or blotching with HDR colours – even over the skin tones or skyscapes that commonly cause striping issues with HDR TVs.
For much of my time with the UHD40 I had to keep pinching myself to be sure I wasn’t dreaming that such a cheap projector could look so good.

T3
A UHD projector for well under £1,500, the UHD40 from Optoma is a cracking deal. It’s pretty easy to setup, thanks to vertical lens shift, decent zoom range and acceptably versatile short throw lens, and the images it produces are a good notch above an HD projector of comparable price.
Naturally, you do get what you pay for to an extent, and this has nothing like the sheen of more expensive UHD projectors, while the HDR, while nice to have, doesn’t pop like it does on the best 4K tellies and projectors.
However, for the price, and with viewing modes to suit most occasions, the Optoma UHD40 is a steal.
