Monitors 1 & 2 Switched! Help!

[thunder0024]

For some reason my PC decided to switch my main monitor with my secondary monitor. How do I switch the ID numbers? Monitor 2 is my main 1080p gaming screen, but 1 is my 720p internet screen. How do I switch those? Whenever I launch games on my 1080p monitor, it caps it at 720p. HOW DO I FIX THIS??

If uou you windows there is an easy fix for it. Just right mousclick on your desktop then go to (rough translation) something like screen resolution and there you should see 2monitors. You can easily dragthem around to switch. It should be that easy... (Was for me)
