Optoma UHZ65 4K Laser

Time for some movies. We’ve got a lot of blu-ray rips on our NAS. Now we would like to play discs as well, but our OPPO 101 gave the ghost just before this test. Luckily we have plenty of other stuff that can display excellent video. Think of our Ultimate Audio PC. Yes: with Kodi on it it can display 4K video. Additional advantage: Kodi decodes everything: from Dolby Digital to DTS TrueHD.

So we connect our PC to the Illusonic IAP8 which in turn provides a B+K 7-channel power amplifier with signal. This one controls a pair of DALI Phantom S-280. For the rear channels we have the Bowers & Wilkins 702 S2. For now we still play with a phantom-center that neatly fishes the Illusonic out of the audio stream for us.

Sharp!

Guys: What a picture is coming out of this projector.

Both 4K material (we have I Am Legend in 4K) and Full-HD material looks very lively and ‘crisp’. To take a cliché: the details are splattering off the screen.

In particular, the fact that Full-HD just looks good is a huge plus. After all, there is not much native-4K material. The majority is 720P or 1080P. The Optoma knows how to deal with that. We’re positively surprised.

Movement?

Sometimes busier passages in a film become a mess. Take one of the first transformer movies. It doesn’t look like that on a moderate LCD TV; it becomes one big blur. The Optoma UHZ65 has a solution: PureMotion. This has to calculate extra frames via processing, which makes it easier to follow fast movement. That’s especially useful with sports. Or busy movies.

We’ve tried, and yes, it works! Without artifacts or other peripheral phenomena. Fact is: you get a bit of the ‘soap opera’ effect. Everything’s getting very sharp. And that’s not always desirable.

The elephant…

Then: rainbow effect. Something every enthusiast talks about with DLP projectors. After all: that colour wheel provides projection of a colour on the DLP chip. In the past that color wheel turned relatively slowly and people could clearly see the effect in lighter passages or in action.

Meanwhile the color wheels turn a lot faster and we are talking about 6-speed colorwheels. This should drastically reduce the rainbow effect. Of the 10 percent it used to really see and suffer from, it must still be about 3 percent now.

We saw it a bit. Think of subtitles on a black background. Or a starry sky. Or perhaps with high-contrast image with movement. But funny enough, you get used to it and after a while of watching it – and not paying attention – it goes away. If we do pay attention to it, it will certainly still be visible to the editor in question. But really disturbing? No. That’s good, because poe: what a beautiful picture this projector puts down.
