This was a mistake. Resolution should have never been the main tag for all screen/display/monitor resolution issues. This is more evident when you get exactly 4 tags for all these issues, created by people that couldn't find the correct tag, or that the tag they found didn't make sense:
resolution name isn't self descriptive. Resolution of what? World hunger? This should be named as any of the other three tags instead. I'm lending towards display-resolution as main tag.
I prefer screen-resolution for reasons related to how multihead works nowadays.
X11, the protocol underlying graphics in Ubuntu until it switches to Mir, defines a "screen" as a single surface that has a resolution and a "display" as the set of screens managed by an X server. (See "multihead" in another distro's wiki.) Thus my netbook has one "display" that consists of two "screens": the internal one (whose "resolution" is 1024x600) and the VGA output (1024x768). If the screens are side-by-side, the display might not even be rectangular. The only relevant meaning for "display resolution" that I can think of is the size of a screenshot covering all the screens that make a display, or possibly with pre-xrandr multihead (Xinerama) that combined all plugged-in monitors into a single X11 screen.
So I'd assume that most should be retagged to either screen-resolution or xrandr.
