NVIDIA Pixel Clock Patcher

NVIDIA Pixel Clock Patcher is a lightweight application that can tweak the parameters of your NVIDIA video driver to remove the resolution and refresh rate limits.
With a zero-footprint on the system, NVIDIA Pixel Clock Patcher requires no installation and will only work on systems that come equipped with a NVIDIA graphics card. It automatically detects the presence of the NVIDIA driver on the computer it is launched on, regardless of the system's architecture (32 or 64-bit).
The NVIDIA Pixel Clock Patcher analyzes all the parameters of the video driver and the GPU, retrieving information about various limits the driver imposes. It targets DL-DVI, SL-DVI/HDMI, the SL-DVI limit on DL-DVL, the SLI limit, and the Fermi limit.
By default, the single-link DVI and HDMI have a pixel clock limit, and so do the dual-link DVI and the SLI GPUs. NVIDIA Pixel Clock Patcher enables you to remove these limitations and exceed the default values, all with the click of a button. NVIDIA Pixel Clock Patcher can only work if all the limits in the list are correctly identified.
Once you decide to patch the values, NVIDIA Pixel Clock Patcher displays a notification message to let you know that the operation has been successful. Nevertheless, the changes are not applied until you reboot the system. Only after that, you can use the NVIDIA Control Panel to switch to higher refresh rates and increased resolutions.
You might be worried that you will not be able to restore the default configuration of your graphics driver, but you should know that NVIDIA Pixel Clock Patcher can instantly restore your video driver to its original state if you run it a second time. In this case, you will see a message saying 'already patched', alongside an option to restore data from backup.
