> fake 10-bit color mode, have terrible color gamut, bad viewing angles, horribly glossy, or some other incredible limitation. From the ad copy of a Dell U2720Q 4K 27": > Exceptional color: Get wide color coverage with 95% DCI-P3 – which covers approximately 25% more color space than sRGB – for true color reproduction. This monitor also offers 99% sRGB and 99% Rec 709 color coverage. > Outstanding color depth: With and outstanding color depth of 1.07 billion colors (that’s 64 times more color depth than standard monitors), excellent peak brightness and a high contrast ratio of 1300:1, images are displayed in true-to-life color with clear details even in dark shadows or brightly lit areas. Be prepared for better color gradation and precision in more shades on this VESA DisplayHDR™ 400 monitor. > True-to-life details: 4K UHD (3840 X 2160) resolution with a high pixel density of 163ppi gives you four times more details than Full HD. > Accurate color, out of the box: Your monitor is factory calibrated at 99% sRGB to an accuracy of Delta-E less than 2 for accurate colors right from the start. - Better color gamut - 178 degree viewing angle - Brighter panel - Anti-glare coated Even if you don't get 10-bit you'll get more accurate colors because the deltaE value is lower. And since you panel is 10 years old panel uniformity will certainly be much better. I bought 2 used 4K Dell U2718Q displays (the older model) for 250 each. The best displays I have ever used. Very worth it. I recommend you demo 1 if you can.
