Thanks for the link. My question would be if certain low quality panels like probably on the T480s flicker more and more over the course of the day due to poor manufacturing tolerances/design and thus contributing to the computer work fatigue over the work day (you feel fine in the morning and later more and more fatigued as the screen silently increases the flicker to add to that fatigue).
Hopefully in your case you don't have to worry about this. I haven't noticed this yet with the 7i just the T480s. 😅
Not exactly my case but interesting:
Display Power: Why TFT LCD Needs Temperature Compensation
However, cold temperatures cause the switch to turn on slower. This steals time (tΔth) to put through the picture
information, see figure below. Less light comes through the filter glass and the contrast gets lower. Visible results
are flickering and/or image sticking of the display.
