I plan to attempt 96Hz tonight, since people like to stream at 48Hz (which would be half). Clearly a single-link DVI connection can handle a lot more than the specs would have you believe. It would be nice if a lot more video drivers would allow you to exceed the spec at your own risk, similar to overclocking a CPU. That failing, we have CRU and the Pixel Clock Patcher .

If it's connected to a dual-link DVI port on your video card, then you're probably hitting the single-link to dual-link switchover point. The patcher only raises the switchover point to 230 MHz to avoid affecting most dual-link DVI monitors. The video card sends a dual-link signal beyond that point, which probably won't work with the capture card. This won't happen if you use the HDMI port on your video card with an HDMI/DVI cable/adapter.

Here is a modified version of the patcher that changes the switchover point to 300 MHz: https://www.monitortests.com/nvlddmkm-pa...le-1.2.zip

You will have to run it twice to restore from backup and repatch the driver. The problem is this modification will also send a single-link DVI signal to the 120 Hz monitor. The monitor might be able to handle that anyway. If not, you'll have to use an HDMI/DVI cable/adapter for the capture card.
