Windows 7 - Force DVI/HDMI resolutions and refresh rates

Windows 7 Home Premium x64
Monitor: Samsung 2233rz

I have been using this monitor on my desktop (Windows 7 Ultimate x64) and it has been working perfectly without any problems.
Recently just bought a new laptop but it doesn't have a DVI port, so I have purchased a DVI dual link to HDMI converter.
The display on the monitor is working correctly but every single resolution is locked at 60 hertz.
When I open up Phoenix and try to Extract a EDID from registry, the box is blank and does not show my monitor.

I am desperate for help and hope there is a fix for this issue.

Edit:
After much research, you can't get 120 hertz from a DVI dual link to HDMI converter.
There are some people saying it is possible with dvi dual link to display port though.

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.

I attempted this process, hoping top add 3D capability with my PC when used with the new Sony 24" Playstation monitor. I had read on other forums that people have been able to get 3D to work with a 120 Hz refesh rate. After following the steps, my computer did allow me to change the refresh rate to 120 Hz. However, the screen goes black and a message appears, "Not Supported". Does anyone have any ideas how I might proceed to troubleshoot this issue? This monitor is advertized to support up to 240 Hz.

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???
