alt Hacker NewsI also have one bought used. It’s the only way to have 4k and 200% scaling on Linux without everything being too big or too small. Size and ppi are perfect but sadly other aspects are becoming really dated (bad colors and contrast, high latency, low refresh rate etc).
Huh. Maybe your particular sample is degrading?
I also have one, and it's holding up pretty well. A month or so ago I broke out my colorimeter and it had almost 100% sRGB at around 120 cd/m2. I don't recall the delta E, but it was very low.
While I didn't measure the backlight, it does seem to not go as bright as before, judging by the levels I set in the OSD. I never went above 70% or so when the sun was shining in the room (not directly on the screen, though), so it didn't have any effect on me.
I understand there are two version, I have the second one. But I don't think there's a difference in the panel itself, I think the change was related to HDMI support.
I can't comment on the latency, the only games I played on it were Civilization and Anno Something. Never had a problem for this.
