The display is actually a small TV that I connected to the PC with HDMI. When I turn the display on everything's tinted green until I change the resolution. It doesn't matter which resolution I use or even if I revert back to the original resolution, the display only needs to be updated and the green tint goes away until the next time I need it.

If I "change" the resolution so the tint goes away, then turn off the display then right back on it stays ok. I havn't experimented with checking for how long I have to wait for the tint to get back, it's my bedroom-TV so I just watch netflix a while once every night.

Since what fixes the problem is some kind of update on the display side of things (turning off/on doesn't count as update for some reason) I doubt there's an issue with graphicsdrivers or cable, but the drivers are updated.

So, what causes a display to have a green tint that only goes away by changing the resolution?

again, this is pure assumption, bit I think that on initial contact certain settings are assume in the initial display setup and the display is created before certain information is passed that allows either the tv or the PC to recognize that something needs to be different, and there is no automated process setup for it to recreate the display afterwards using the correct format/display/etc. It may even be the format data is passed through the cable needs to be changed and so it reestablishes the data link.

This would make the most sense to be given what you described and what I know of software.

So when you recreate the display by changing a display setting, that correct change is automatically added in.

So, if a certain...
Someone will probably answer better, but I am assuming the color profile is different on the TV than on a typical PC monitor. And that the refresh updates one side or the other to adjust/set the correct color profile that will work with the display....maybe?

EDIT
I have a better answer, the colors that TV's uses as base based on old cable scheme is different than computers

So, if a certain amount of time passes, or the monitor loses power, etc, the computer "forgets" the display and makes the same bad assumption the next time instead of using an already existing profile for that display. TBH I assume the issue is on the PC side, but if not a super old tv, could be TV side where there is volatile memory profile for connection(or profile set to expire after certain time)

FURTHER EDIT>
You have to realize that Computer Display stuff and TV stuff did not exactly develop from the same place, more side by side with hardware shared partly, and software being mostly different. Displaying to TV's is different to PC monitors, color profiles can be different, the base colors that they use can be different, tons of things. RGB is typical base colors for a PC monitor, but there are several other base colors different software/technologies use and some systems will need to convert to get things to work right. I'm no video expert, so the exact formats are beyond me lol
