To add to the magic: although the projector is so close to the canvas, it creates a large image. This eliminates the logistical problems that could put you off buying a projector. Place the projector right below the screen and nobody will block the picture when they get beer. Optoma's UHZ65UST also boasts laser technology. This means, there’s no Xenon lamp that needs to be maintained and replaced after about 3,000 operating hours. Instead, a laser – or rather several small laser diodes bundled into a beam of light – lasts for about 20,000 hours. If your projector is on 8 hours a day, that’s about seven years of use. On top of this, laser projectors are much brighter than lamp projectors. This is great in light-flooded living rooms, as a picture that’s too dark would hardly be visible. In our improvised living room in the digitec studio, the lighting conditions aren’t quite as critical. And Optoma’s UHZ65UST – I need to find a better name for this thing – doesn’t seem bulky, even though it’s almost 60 centimetres wide and 13 centimetres high. Still, with its brass feet and fabric front, it could pass as a chic soundbar, as video producer Stephi claims. Okay, this interior design isn’t Stephi’s work, it’s our improvised digitec «living room.» She has a much better understanding of interior design than I do. Speaking of soundbars: Optoma bought its audio technology years ago by taking over the company NuForce. I must say, the loudspeakers that are built into the projector provide fantastic sound. When it’s on, the projector isn’t loud – a pleasant 26 decibels, that’s as loud as the ticking of a wristwatch. LG's projector achieves the same noise level, but only in eco mode. This saves electricity, but also reduces the image quality. Optoma’s UHZ65UST is a UHD projector, but it doesn’t offer true UHD resolution. Yet, they’re allowed to call themselves UHD projectors because the DLP e-Shift Technology developed by Texas Instruments creates a kind of artificial UHD. To be precise, the image is created on a standard Full-HD DMD chip. This chip is made to vibrate so subtle and so fast that the human eye cannot perceive the vibration. Instead, it looks as if the Full HD image is multiplied four times and placed next to each other, resulting in a resolution four times higher than Full HD. If you’d like to know exactly how this e-Shift Technology works, check out this article (only available in German). The top left and top right corners are often slightly blurred with UST projectors. These slightly blurred corners were noticeable with LG's HU85LS. I'm beginning to understand what Optoma means with «perfect for recreating the big-screen experience at home», even though these marketing promises still sends shivers down my spine. Good colour management thanks to HDR and HLG supportģ500 ANSI lumens – this is how much brightness Optoma’s UST projector delivers. In comparison, LG's HU85LS achieves about 2700 ANSI lumens. With too much brightness, colours will appear faded. This is why most projectors don't (want to) produce more than 2000 ANSI lumens. However, it needs about 2000 ANSI lumen to make sure the picture is good enough in bright daylight. It really is a balancing act between too much and too little brightness. Optoma has the advantage that its projector dynamically adjusts the brightness to the ambient light. In the evening – or in a darkened living room – you don’t want a picture that’s as bright as the midday sun in the Gobi Desert south of Mongolia. #Projektor leinwand test full#ħ09 colour space (Blu-rays, Full HD content) 87% coverage of the HDR relevant DCI-P3 colour space (UHD Blu-rays, UHD contents). These values are good for a laser projector. Most laser projectors only achieve a colour space coverage of about 80-85% of the DCI-P3 colour space. The UHD Alliance awards the «Ultra HD Premium» label for a DCI-P3 coverage of 90% or more.
