Had perfect 1920 x 1080 resolution on my VGA output now its gone?
I have a ATI Mobility Radeon HD 5730 graphics card and was running 2 external monitors perfectly off of it. One hdmi and one VGA at full HD 1920 x 1080p.... Life was good..... Then I turn my computer on one day and the VGA connected monitor no longer supports 1920 X 1080p it only accepts 1600 x 1200. Now When I first set these up I had to add the 1920 x 1080 resolution using the Catalyst Control Center so I figured something got changed in there. I go back and for the life of me can not change it back. I even installed powerstrip and it will not allow me to add 1920 x 1080 for the VGA connected monitor either.
Notes: *Both monitors connected are the same 42 inch LG tvs only difference is one is connected with HDMI and one VGA
*both monitors previously displayed 1920 x 1080 great no idea what changed
*I do not know if this is the issue or not but it appears that Catalyst Control panel will only let me select 30herts refresh rate for 1920 x 1080 when it was 60hertz but even then it does not matter because it just goes back to 1600 x 1200
* I have now spent 8 hours trying everything in the world, unplugging monitors, installing and reinstalling drivers, going backwards with drivers, going forwards with drivers and nothing works. My VGA connected monitor can not be forced back into its wonderful 1920 x 1080p resolution. I am completely at a loss for words and have no idea what to do or what happened.
Anyone who can help with be a savior.

have you tried changing the resolution via windows? right click desktop - properties - settings You can deinstall catalyst control center without deinstalling the driver. add/remove programs via control panel try that. why do you use vga anyway? don't you have two another dvi beside the hdmi? if all that fails... weird. try setting both monitors to factory default via their on screen cp then.
Of course I tried through windows 100 times... I uninstalled Catalyst.. I used powerstrip... Tried lots of things. I have to use VGA because my laptop only has 1 hdmi and 1 vga out.
so the vga connected monitor displays '1080p not supported' right? try plugging in the other one to vga and see if same error is displayed = if yes you know it's NOT a problem with one of your monitors.
another crazy idea. do you have some kind of keyboard shortcut command that might override with a external max. resolution?
there is no problem with either monitor. The only problem is the VGA display whichever it is plugged into will not display 1080p full hd and it used to.
