I have a few confirmed resolutions:
1680x1050 (my laptop, and several screens at work use this)
1280x1024 (work still has several 5:4 ratio 19" screens)
2560x1440 (main screen)
1024x600 (netbook)
540x960 (phone)
1200x1600 (secondary screen)
And some that are very likely:
1280x720 (if I manage to break the procrastination and get the projector and rest of media centre up and running)
1920x1080 (if upscaled to higher counts)
640x480 (if I get the old machines back into usable state, and old games upscaled on higher-resolution monitors)
800x600 (ditto)
1024x768 (ditto)
Also a couple that are less likely, but I hope I'll reach:
2048x1536 (mostly depending on whether or not I decide to get the Jolla Tablet - I see little use for it, much less one that's worth the cost, and it seems a bit too small, but I do want it)
3840x2160 (quite unlikely that I'll get a 4k screen... it'd be nice though)
1600x900 downscaled to 1280x720?
