Windows 10: Resolution problems

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.

Resolution Problem

This is how I finally fix 1600x900 problem in my W-10 upgrade.

I looked into my old -Downloads- files and reinstall the following

application that was deleted by W-10 installation;

6.08-Nvidia-System-Tools file version 4.0.100.1190 size 71.8 MB

I have a HP p6203w Desktop

windows 7 home prem - default OS

video card-NVIDIA GeForce 6150SE nForce 430 v. 309.08

Good Luck- Luis

 

I am assuming after installing WinX you updated all your display drivers? If you would provide a bit more insight into your system it would facilitate troubleshooting this problem. couple questions come to mind 1) are these both running off of 1 GPU or is there a crossfire set up? 2) what are your system specs as far as what GPU are you running, how its connected to the monitors in question. Any information you can provide will greatly help any of us here to help you with your issue.

 

just 1 gpu with drivers updated, uninstalled, reinstalled x7 or more times with different driver versions dating back close to 2 years till present, main is hdmi, 20" is dvi-d

 

I found the problem; I had to change the actual monitor resolution by changing the Adapter Properties' "List all modes" pull down menu from the display settings and Display adapter properties link. Any other attempt to change the monitor's resolution ended up only changing the screen resolution, thereby keeping the monitor to the "recommended setting" of 1080p. It looked like it was changed, but only the desktop changes.
