NVIDIA Pixel Clock Patcher: remove resolution and refresh rate limits

[harlan4096]

NVIDIA Pixel Clock Patcher is a free program for Microsoft Windows devices that removes certain resolution and refresh rate limits.

The program detects limits and may patch the values to allow higher resolutions and refresh rates. It checks for certain limits and displays those that it finds in the interface. In the case of our test machine, DL-DVI, SL-DVI/HDMI, HDMI-DVI, SL-DVI on DL-DVI, TMDS.

You may download the latest version of the NVIDIA Pixel Clock Patcher from the developer's website. The program is updated regularly to address changes in newer drivers that Nvidia releases regularly.

NVIDIA Pixel Clock Patcher modifies the NVIDIA video driver to allow higher resolutions and refresh rates by removing the 165 MHz pixel clock limit for single-link DVI and HDMI, the 330 MHz limit for dual-link DVI, and the 400 MHz limit for SLI and 400/500-series GPUs.

NVIDIA Pixel Clock Patcher

NVIDIA Pixel Clock Patcher requires a Nvidia 400-series or newer graphics processing unit and Windows Vista or newer.

The archive that you download comes with two executable files:

* nvlddmkm-patcher.exe -- the regular patcher

*nvlddmkm-patcher-full.exe -- the patcher for Catleap/QNIX/Tempest/X-Star users with with 400/500-series GPUs.

The application detects existing limits on start. You may select "yes" to patch the limits or "no" to cancel the entire process. Nvidia Pixel Clock Patcher displays a notification after the patching. Note that you may need to reboot the system before the new options become available.

We suggest that you create a backup of the system before you run the patch. Note that new driver installations will undo the changes made by the patch. You need to run the application again to patch the values after new driver installations.

The application creates a backup and when you run it again includes an option to restore the defaults.
