Dell U3223QE sRGB 8,8,8 line pattern bug
(Watch in 4K/8K.) So, this monitor is great — but if you are using a color space mode, and if a "large enough" portion of the screen is taken up by a block of 8,8,8 (or 8,7,8 / 8,7,7 etc. but NOT 7,7,7 or 9,9,9) then a slight pattern of "dark lines,every other line" appears. It's very subtle but it's there.
In this video, I'm in Photoshop, with a canvas of nothing but 8,8,8, and dragging the slider in the "Levels" tool to be able to easily trigger this pattern, back and forth.
This doesn't happen in standard mode.
