The ProArt Projector A1 was designed for creative professionals and comes fully calibrated to a Delta E2 color accuracy. It contains 98 percent of the colors found in the sRGB and Rec. 709 color space... Calman Verified ProArt Projector A1 Launched by ASUS
I doubt any creative professionals want to work on your "4K" projector that has a contrast ratio of 6.
My projector is clear as day I can even watch it with windows and lights on. It has a 1,000,000 / 1 contrast ratio.... Acer 4K DLP Projector with Stereo Speakers | H7850 Contrast Ratio: 1,000,000:1
Do you understand what contrast ratio is and how to measure it? That manufacturer rating means nothing - all the monitors we used are rating at that "dynamic" contrast ratio and in reality, most of them struggle to hit above ~ 1000:1 (or 3000:1 for VA).
That's not a native 4K projector, it's 1080p projector with pixel-shift. It's million to one is dynamic, not ANSI rated. It also retailed for $2000.. so I'm not sure why you're comparing your used or however you got it for $800 pricepoint to a new projector. It doesn't support keystone correction and it doesn't even come close to the color accuracy the proart does. The projector linked in the OP is for creative artists that want color accuracy above all else. I don't know why they'd use a projector for that honestly, but ASUS feels like people out there want it so here it is. Comparing your 3 year old projector with pseudo upscaling/contrast ratio + average calibration and used pricepoint doesn't mean much to anyone that knows projectors. I'm sure it's great for your space and I'm glad you got a good deal on it, but it's not the same thing and your being mislead by marketing and essentially just spreading the marketing here.
I wish more displays where full callibrated. i dont get why in this time i not done it not like cost 100's of dollars to do it special if you already have the stuff
