Im having Acer TV which im using as a monitor by VGA cable running at 1440x900 and at 75hz. I turned on pc today and while i was looking for something i noticed that the screen isnt fluent as it should be. When i got into display properties it says that is Generic Non-PnP monitor but it was Generic PnP monitor. Screen refresh rate was set to 60hz and i couldnt change it back to 75hz but my resolution is still unchanged so resolution is okay but refresh rate isnt. I also got into properties and it says
Device type: Monitors
Manufacturer: (Standard monitor types)
But previously it was displaying all the infos normally.
Then i tried in Radeon driver to see what is happening. Everything was displayed as Not supported

I was actually messing with drivers like a week ago because i have had a problem with crimson drivers which cant update to newer crimson driver and its displaying some error so i installed old catalyst driver and then uninstall crimson.
Graphics card: AMD(Gigabyte)Radeon HD 6570
Current driver: Catalyst 15.7.1
Thanks for help
