I got some refresh rates to work with some of the timing adjustments I found in this thread. So far the highest I can get is 74hz without any obvious issues. Anything above 80hz won't even display. I get a black screen. The display I'm using is a Vizio 240hz 1080p telly. What I wanted to know is how one would determine the proper timing values for a given refresh rate/resolution and is there any way to get a higher refresh than 74hz? Thank you very much in advance for any help

The TV might not be able to handle higher refresh rates. Keep in mind the 165 MHz pixel clock limit. If you're using HDMI with the extension block enabled and the refresh rate is listed in the Windows screen resolution settings, then you don't have to worry about this. If the refresh rate isn't listed, then you'll have to patch the driver to go higher.

Three timings you can try:

1. Add a detailed resolution and just change the refresh rate.
2. Try the "LCD standard" option.
3. Try the "LCD reduced" option.
