I have two screens; The main one I use is a 47" 1080p tv. The other one is a 20.1" 1680x1050 max monitor which I use in another room which is used a few times a week.
For some reason, I can't seem to lower the resolution of either monitors lower than 1080p. I set the main one to 720p, the screen seems to change (icons and text get larger), but when I use the tv remote to view the resolution, it still shows 1080p. When I duplicate the displays to the 1050max monitor, windows 10 tries to set the resolution to 1080p and the monitor image shrinks to just a line of light and has a high pitched sound coming from it, and is unusable... and may possibly damage the monitor. Trying to lower the resolution during that time doesn't work... it shows that it's changing, the screen flickers and comes back on, but the monitors still show 1080p even though the icons, text, etc. all look like 720p (or whatever res. I set it to).
I've tried pretty much everything from changing the AMD CCC resolutions to the Windows 10 display resolutions, and nothing works. The only way to actually get the 20 inch monitor to work is to physically unplug the 47" monitor and reboot using the 20", and that's very annoying to do.
I'm just wondering if I'm missing something? After the full install (not upgrade) I didn't change any of the settings, when I first tried to connect both monitors. Lowering the resolution does not work, it just looks like it does, but the monitors stay at 1080p. Do I have a bad windows 10 install and should I reinstall it? On my other HD I still have windows 7, and everything works as it should, but windows 10 has that major problem.
