Force DVI/HDMI resolutions and refresh rates

Here's a new one. I need to find a way of forcing 5.1 surround sound.

I've read through the forums and can't seem to find a solution to this problem:

My HTPC is connected by HDMI to my Onkyo AV receiver over a long distance, and this works perfectly to give me 5.1 Audio and 1080p. No worries with resolution. However, I have an HDMI matrix which feeds a second TV in another room. It works great, except for one thing. When the second TV is turned on it is detected (correctly) as stereo and bumps the whole system down into stereo mode. I have an older Panasonic TV which played nice with 5.1 whilst outputting stereo from its own speakers, so I suspect that this one will cope with a forced 5.1, but it's EDID does not allow this automatically.

So, it is my understanding that, as well as video, audio is handled by EDID. However, tools like Phoenix seem only to have settings for monitor timings. Am I missing something buried in the software, or does anyone know of any other tools/methods of solving this?

Please note that my HTPC is on the other side of the house so I would like to avoid wiring up new cables!

Any help would be greatly appreciated.

Dear All,

I'm writing following my purchase of a HD, 3D Television which I'm using as a monitor: A Viera/Panasonic TX-P42UT30B. Having seen its alleged capabilities to have been up to 600hz refresh rate advertised in store, I grabbed it but am uncertain of the purchase now that Windows 7 only allows for 60hz.

Please could someone bring closure to this in suggesting how I could go about setting my TV safely to a higher refresh rate, resuming a resolution of 1080p in the meantime (SAFELY)? I am using a GTX 550 Ti (Nvidia, PNY) With HDMI>Mini HDMI.

I'd be extremely grateful for anyone's help here. I've tried revealing the unlisted modes on Windows, but it doesn't allow for anything over 60hz.

Thanks very much!

Chris

Is there any way to mod a dvi-D single link cable to prevent edid info ?

I have a
LG 42LV5400

It should do 1920x 1080 120 hz


I only get 60 hz and lower in the nvidia control panel
I have a Nvidia GTX 580 connected to the display through mini hdmi to hdmi


I opened phoenix but I cant find where to edit the native refresh rate and resolution could someone help please

so i was able to do 85hz with phoenix, it actually does 85hz without any problem , but it keeps showing a watermark on-screen saying "mode not supported"

but it actually does 85hz, i can see the difference between 75hz .-.

any1 knows how to fix this???

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.

i have installed graphic card and monitor driver but i cant go 75hz and cata control center not show details for monitor my monitor bugged or graphic card?

Hey all,

Hoping I can get some better understanding of how to use the Phoenix EDID for my particular issue.

I basically need to force a resolution for my monitor that is 1920x1080 16:9 60hz, however, I do not want the possibility of any other resolution at all.

I am having a hard time understanding how I can do this with the EDID information from Phoenix. Is this possible? Can anyone give me a quick walkthrough of how to do it if it can be done?

I tried to disable everything in the standard timings but what I have above, but I am unsure if it worked as I was still able to reduce the resolution through windows, which is obviously an issue for what I need to accomplish.

Thanks for your help!
