Why can't I play certain games on my hdtv through vga

Ok...so I purchased an RCA 37" LCD Flatscreen.  I have been loving the VGA hookup that allows me to connect my pc and use it as a large monitor.  I have had no problems in the past playing games on it until about a week ago.  I've tried reinstalling drivers and modifying settings on my video card and nothing is working.  I have an ATI Radeon X1650 512mb and can still play games on my 19" Acer monitor.  I currently can play a disney game called "PURE" that has great graphics and performance.  I am still unable to play games such as: Half Life 2, FEAR, Madden 08, Oblivion, Call of Duty 4, & Need For Speed: Pro Street.  I have also tried updating my DirectX and had no luck. All I get is sound and a black screen.  I am almost at my wit's end with this....

It's the TV.. what is the max resolution it will support?  Most likely 800x600 or 1024x768.. what is the model #?  It's not the PC thats the issue.

1360x1024 is the max that displays. I usually keep it in the standard 1280x1024 for the most part tho.  I can use the tv just fine with the VGA hookup for doing my basic graphic design and what not.  It's only when I try to play games. I've tried adjusting the resolution to a lower setting and still no go.

 MODEL: #L37WD12YX1

Aha!  That would be the one thing I didn't try.  It was the refresh rate.  Set it to 60 and bam we're back in business.  Thanks for the quick response!
