Dynex 55"--can't force 1920x1080 60Hz

[kyonu]

Okay, so I have a new Dynex 55" TV that seems to have a pretty crappy response time, but when I plug it into my computer via HDMI my mouse gets a delay that's causing all sorts of problems, such as it is not where I want it to be when I move my hand there.

I've been looking around other forums and people have been able to force 1920x1080 59Hz (60Hz mode) Progressive in the NVIDIA Control Panel and the TV performs just like a monitor... But I can't for the life of me figure this out in the ATI CCC.

Does anyone know how I can force a resolution of 1920x1080 59Hz (60Hz)? The "Custom" resolutions are a joke since we can't specify a Hertz number, and everytime I try changing the hertz in the Desktop Properties section of CCC, it just reverts back to 60Hz (TV supports 60, 59, 50 hz). In the Windows 7 Management I can change it to 59Hz, but it doesn't modify anything.

I have an ASUS G73 laptop with an nVidia GTX460 in it and I was able to reproduce the 1920x1080 59Hz trick very quickly and it was very effective.

My desktop video card is the Radeon HD5770 1GB.

Someone PLEASE help me find out how to do this...

Does anyone have any idea?

It's obvious that Dynex support doesn't know what they are doing... I sent them an e-mail about this but they replied back to me... asking me if I tried plugging in VGA and wiggling the cord to get a picture... And also told me "we are sorry you are having problems with your HDTV turning on randomly". So, I'm stuck without their help.

Thanks again.

I haven't run ATI in forever but you may get more responses asking in the Video Cards and Graphics forum since you are trying to do it on the computer end and not the TV end.

Thanks for the advice, I will try this.
