Optoma UHD65 4K Projector Review

The Optoma UDH65 is the most expensive UHD projector we've looked at so far. It's a mid-range 4K device with an impressive specification and and even more impressive results.

On paper it's a projector with numbers to die for. It's a DLP projector with a conventional bulb, but one which offers a contrast ratio of 1,200,000:1 - not a typo - 1.2 million to one. In reality that equates to one of the most impressive colour ranges of a projector we've tried to date and when coupled with a good HDR 4K Blu-ray it's astounding. Surprisingly, the 2,200 ANSI Lumens the bulb kicks out is lower than you'd expect - there's no denying that the UHD65 isn't a projector to use in ambient light. It's designed for as dark and environment as possible but when given those conditions it performs better than any projector we've seen.

The lower brightness of the lamp means the image doesn't suffer from bloom in the slightest. Blacks are black, whites are white and every colour between is accurately reproduced. Across the average room expect to achieve a screen size between 90 and 110 inches (2.2-2.9m) but the UHD65 is impressive in that it can achieve a screen of up to 300 inches (7.8m) with no impact in the overall picture quality. It's well suited to large dedicated home cinema rooms.

As with the previous Optoma 4K projector we've reviewed - the UHD51 - the UHD65 doesn't support keystone correction, prioritising non-digitally meddled with picture quality over flexibility. This mean that it needs to be properly mounted to ensure a straight line between projector and screen - with 4K in mind this is actually a sensible decision for a mid-range device even if it does bring with it logistical issues. The projector can output a test pattern to help with perfect positioning. Other configuration options include the ability to specify the colour of the surface on which the image is projected with the UHD65 then modifying it's output to compensate for any colour hues. Great for people without dedicated screens and while most will want to tweak the image colours for the perfect display it provides an excellent starting point.

We've tested the UHD65 with a number of sources from standard 1080p through to HDR 4K Blu-rays. Everything we've thrown at it has been handled wonderfully. Watching Star Trek Beyond in 1080 as a baseline showed that the UHD65 was able to handle HD material well with the film's vibrant colour palette being delivered beautifully - the bright primary colours of the Starfleet uniforms looked amazing. That was until we then popped in the 4K version of the same film and ended up with something that almost looked 3D as a result. While the colours looked great in HD, they were truly astounding when HDR was thrown into the mix with the added depth bringing about something that was as lifelike as we've seen. The added detail brought by the increased resolution made for an end result that was better than any cinema showing we've seen.

Similar results were seen with 4K material via Netflix and while the increase resolution did expose compression artefacts that come with online streaming the sharp edges and deep colours of HDR more than outweighed this.

Connectivity is adequate; there are two HDMI sockets, one 4K HDCP2.2 compliant although we'd have preferred both to be to enable for both a 4K Blu-ray player and another 4K device to be connected at the same time. There is a powered USB socket that means dongles can be supported and both audio inputs and outputs - including and SP/DIF connection. There is also VGA support for legacy PC connections.

The UHD65 is an impressive projector by any measure and the best we've seen with a conventional lamp. The price may place it out of the reach of many but for someone looking for an excellent mid-range solution for a dedicated home cinema room there aren't really any better options. at this price point. For those who want better ambient light performance the UHD60 might be a better option, but for those who can make the best use out of it the UHD65 is the perfect solution.

Addendum: be careful when ordering online as many listings with online retailers are actually for the standard HD Optoma 143x despite saying they're for the UHD65 - double check the specifications on the retailer site for peace of mind.


Optoma's mid-range UHD projector impresses with stunning picture quality and impressive colours.
