nVidia Card Driver Problem connecting to a TV

Hi. I hope you guys can help. I'm having a problem connecting my PC to my TV.

Whenever I connect the PC to the TV (via a VGA cable) I get a message on the TV saying "Not Supported" which is the message you get when the TV doesn't support that resolution.

The thing is I know it CAN support that resolution as I've hooked PCs up to it in the past at that resolution, and it states clearly in the TV's manual which resolution it supports.

The thing is I can boot it in Safe Mode (you only get the message when the windows desktop appears), and it works fine (you can change the resolution with no problems). However you can't boot it in low-res mode.

This sounds like a driver issue, and if you disable the GPU's drivers (by using Device Manager) it all works fine.

I've updated, rolled back, and tried different drivers, but the problem persists.

Any ideas on what to do?

My card is an nVidia GeForce 9400GT, and the TV is a Hyundai HTLY37f2
 
I'm having a similar problem with my new PC.
I have a GTX 570, and I get the on-screen message of "Mode Not Supported" but only when I try to use HDMI (Using VGA is fine).

I've tried changing the resolution but it didn't work.

I'm guessing the solution to both our problems is pretty similar (or maybe not) so, now there are two of us asking for help! :(
 
Sounds like refresh rate as others have stated TBH. Doesn't sound like resolution as you have already done the obvious steps there.
 
Ok. I've sorted something out, but to be honest this is even more bizzare.

I connected it to the monitor of my main PC (which works fine). Then I connected the TV as a secondary monitor. I actually managed to get it working, and it looked fine (right resolution and everything). I then set the TV as the primary monitor. Everything was fine. I disconnected the other monitor, and then the "Not Supported" message came on again. :(

What is wrong?! I want this PC as a HTPC so I NEED it to connect to this TV.
