I messed with color settings a lot, and the best for me was -1 contrast Red, and +1 Brightness Blue. I can see every shade now, where initially the last 3 red looked the same and first blue was basically black: Contrast - Lagom LCD test
Yeah I’ve noticed a slight difference between left and right eye as well, but only when looking at my headset from far away… not noticeable when wearing it. Colors are very natural-looking in the 8KX, which I prefer. Valve Index and Quest 2 colors “pop” just a little more, but it’s almost too vibrant. Maybe that’s the workaround that manufacturers are doing for an LCD vs OLED display?
