Force DVI/HDMI resolutions and refresh rates

thats what i dont understand, when i do that it says out of range/frequency.

There's been some confusion over the fact that Windows 7 now uses Electronic Industries Alliance (EIA-861B) TV-compatible timings. This explains it from the NTSC standpoint: Screen refresh rate in Windows 7 does not apply the user selected settings on monitors & TVs (that report specific TV compatible timings)

Even though the KB does not go into it, PAL and SECAM rates are also affected so your 100Hz is actually getting set to 100/1001*100Hz or ~99.9Hz by Windows 7 and the driver. See if you can set a custom rate of 100.1 or see this if you're an nVidia guy:

Advanced Timings

Here's a good explanation of where these weird timings came from: Frame+Rate+Follies.pdf

I have no idea about what that all means. What do I need to do exactly?

Look for the following page in Catalyst Control Center and set the controls as in the picture. No guarantee that it will work but it's worth a try.

Use the ATI control panel to do the resolution and frequency change. Do not involve the Windows control panel at all. I suspect a difference....

What troubles me is that I do that and it works but still says I have only 85hz when I press the menu button on my monitor. The first picture is what happens when I check that box and and apply it to the resolution 1024x768.

You still need to set the resolution after doing that. It just sets the source for the resolution LIMIT not the resolution SETTING.

Hi guys, im having a problem with my TV an LG 32LF15R, i was using my MSI TWIn FROZR GTX 460 768 MB, conected to this tv using a DVI to HDMI converter wich came in the box with the Video Card. TV HDMI input and video card has the converter and an HMDI out.SO.

I was working with an 1920x1080i resolution. It worked flawlessly for about 4 or 5 months, and one day about a week ago i turned on my PC. And nothing all i get its a NO SIGNAL message and now my PC doesnt even detects my TV. I was able to transmit sound to the TV and Video without any problems.

Now cheking on the LG website i realized that this particular monitor supports 1366 x 768p HD resolution so im kinda lost now, why was i able to set higher resolutions if it sopposedly only supported 1366 x 768p ??.

So my pc is not detecting the TV at all i tried using a different cable, tried with the MIni HDMI, and both DVI ports in the back of the card and nothing. im knda sad here so if u could lend me a hand here that but be AWESOME.

and something else, my TV displayed always everything, im talking about the bios and everithing, it was detected when the pc booted.

my question here is if i can force a resolution/refresh rate so the TV is detected again ? is this possible ?
