Hello,
My LG E2251 Super LED Flatron Monitor I am nearly convinced is causing me some severe lag / display issues during startup of computer games that are graphic intensive.

I have a 560 GX twinfrozer graphics card by MSI. ,3.2 CPU, 4 gigs ram.
Prior to purchasing this monitor I had a 17in flat generic monitor that played everything with no fuss.

Since getting something that can display at 1920x1080 natively. Almost all games startup just fine, then shortly after become very slow/freeze/crashing.

It should be unnecessary to reinstall all my games dont you think?

I have played around with the settings but all seem to simply crash eventually, act incredibly slow, black screen, or zero response from the keyboard. I have changed to 1024x780 and made sure that the refresh was within 60Mhz, as this is what the monitor can handle.

Nividia drivers are the latest, and I have also tried going back to a previous version.

Other news - I did upgrade the generic keyboard to a Logitech G105 blue led "gamer" keyboard. Could it be this too?

really sad about upgrading and feeling like I actually downgraded.

:(

Thanks in advance for any advice.

UPDATE

I used a program to read the following

Maybe posting this, someone can see if my monitor is failing to post the correct resolution? Or something else. Thanks in advance.
