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. There is no actual gamma standard for HDTV content, and people have different opinions about the correct one, but being able to choose one is important, and having a screen that doesn’t modify the projector’s settings is ideal.The UHD Alliance awards the «Ultra HD Premium» label for a DCI-P3 coverage of 90% or more. The gamma curve in a display accounts for this, making it so every incremental step is visible to you.

If you have 255 light bulbs in a room, going from one light on to 2 lights is a much larger difference to your eye than going from 235 lights to 236.

Gamma: The idea behind gamma is that your eye perceives changes in light levels in a non-linear way.

This chart shows the HDTV color points inside of the CIE 1931 diagram. If a device can’t show all of these colors, or shows colors past them, the resulting image will look different from what it is supposed to. Otherwise the content would look completely different depending on what you watched it on.

Because of this, we set a target for what these colors are in movies and TV shows and have display devices use those. We don’t have the technology today to show all the shades of red, green, blue, and other colors you see in nature. Color points: The colors the human eye can see are defined by the CIE 1931 chart, but no TV or projector can display all of those.It’s actually neutral, and the Cool setting is blue, fooling your eye. If you’re used to the Cool or Dynamic setting on your TV, D65 will likely seem reddish. HDTV and UHD use D65 as the color temperature for white, which is based on the midday sun in the Northern Hemisphere. The HDTV specification dictates a very exact neutral white. White can range from bluish white to reddish white. White point or “color temperature”: This is literally the color of white that you see on screen.
