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.

Its a single-link DVI port on the video card that goes to the capture card.

I have a GTX 680, which has:
1 HDMI (unused), 1 DisplayPort (unused), 1 dual-link DVI (120Hz Monitor), 1 single-link DVI (capture card).

I don't really want to send a single-link signal to my 120Hz monitor connection, but that's still interesting information. In a bit I'll try setting the Hz down slightly so it falls at or just under 230 MHz and see what happens. Also the 96Hz setting.

I could use the DisplayPort for my 120Hz monitor instead (I have a BenQ with both inputs), but I can't see a display that way until it gets into Windows, the video card defaults to DVI for the Bios and bootup.
