Force DVI/HDMI resolutions and refresh rates

Hi, I have a problem with my LCD 32''. The native resolution is 1280x720. I have no problem setting it and even no problems forcing the refresh rate to 75hz (as I had it on WinXP but no forced then).

The problem is that I had the edges off the screen. So the "default" resolution happens to be 1216x684. I can't force the refresh rate with that resolution and some games didn't recognize it (only has the "standards" on wich I had the edges off the screen).

I tried a few nvidia drivers (I have a MSI GTX560 Ti) and a couple of the tweaked ones and nothing.
The TV doesn't has any options to resize the screen (i mean, in the remote).

I've tried the tutorial. I can generate the *.INF and "update" the monitor driver, but nothing happens after the reboot, the refresh rate is the same, also the resolution and obviously, the edges are off the screen.

Any help?
Thanks in advance.

The problem is that I had the edges off the screen. So the "default" resolution happens to be 1202x684 (I know it isn't 16:9, I set it manually so it's possibly that I missed a few pixels).

Look for this control in the nVidia control panel:

I'm not having blurry problems. I tried that control and nothing changed. Off game and in game, the edges are still off the screen.

In game is less annoying because new games always recognize the windows resolution (1216x684) and can play "full screen".
Off game it's really the problem because the media player controls are always off screen as well as all the movies borders (of course the task bar too).

Same issue as the other guy. He just set his media players like they were games...

I've tried that solution and still no changes. The games only run "full screen" when I can select 1216x684 in its menu. If I choose 1280x720 the game goes out of screen.


EDIT: I could fix it thanks to this post: HDMI: How to disable?.
The thing was to use the TV with the DVI connection. In the first page you have the complete workaround and a few pages later you have a registry solution (based on the first one) wich is the one I used. No re-installing drivers, just modifying a key in the registry, restarting and working :)

It even worked with a TV, despite that workaround is mainly for monitors.

Hi to everyone, I'm here sitting at my desk after pulling up an all-nighter together with most of my hair.
I extensively read through the whole thread, but solving the problem is beyond my mental capabilities at this point and in such state of mind.
I was using an ATI 4890 with Win764 and all was going smooth.
I recently upgraded to a 6950 (together with new system components), and now I can't play games above 60Hz.
More specifically I was able to run my desktop native at 1280x1024 and select 100Hz only after unchecking "hide modes that this monitor cannot display". Not much of a problem, and I was happy with it.

Next I install a game (DiRT2) and find out I can only play at 60Hz, no matter what I do., and the ingame menu only shows up to 85Hz anyway (even if Windows and CCC let me choose 100Hz)

AT this point I start following the tutorial on page 1 to create a new .inf file, and all I can get is the ingame menu of DiRT2 to show 100Hz as well. Still, the game defaults the monitor to 60Hz. But there is something new: now I can play it at 100Hz BUT ONLY IN A WINDOW!

Additional step, I remove pin 7 from a spare VGA to DVI adapter and do the .inf trick all over from the start. At this point I get an added bonus: DiRT2 is now running at 75Hz.

I see this as a step in the right direction, but not quite satisfactory, as the 4890 allowed me to play ALL games at 1280x1024@100Hz.

Here is where I give up, re-fitting my intact VGA to DVI adapter and calling it a day.

One thing I *think* I understood: Phoenix reports 1280x1024@75HZ only as a VESA Established timing. I have a feeling that until I can't change that reading to 1280x1024@100Hz, I won't be able to solve the problem. Thing is, I DON?T HAVE ANY IDEA HOW TO DO THAT, nor whether it can be done at all.

My monitor is a 22" Samsung Syncmaster 1100DF with great viewing surface and good color fidelity. I have no intention to change it, especially since I've run dry with finances after upgrading the system. The alternative at the moment is to leave my pc off until I can afford a new monitor.

I hope someone can help me out. :)

No adapters. No broken pins. This tutorial only works if your monitor is connected to your video card natively. Otherwise all bets are off. I will tell you this (as the tutorial author) you need to create a custom timing. The VESA standard timings do not go to 100Hz. See if you can connect your monitor using a native VGA plug or borrow a DVI monitor to complete your testing.

HDMI signal is digitally identical to the DVI output. Your TV is detected as a TV so it did the overscan. I'm positive that if you'd set the programs in nVidia control panel correctly you'd have been fine as well.
