Try the "LCD reduced" option in the timing drop-down list in the detailed resolution dialog. That will keep the pixel clock under 165 MHz, but the settings may not work with your monitor. You can put in 71.928 Hz to get close to a multiple of 23.976. (04-06-2013 10:01 PM)Mangix Wrote: How does reduced work? I know that it lowers horizontal/vertical blanking but is there any standard for it anywhere? The reason I ask has to do with my second question:It's non-standard based on what works with different monitors I've used. The goal is to keep the pixel clock from going above 165 MHz or 330 MHz, if possible. 2560x1600 @ 70 Hz with "LCD standard" is still below 330 MHz, while 75 Hz is not. I was considering making it reduce all refresh rates above 60 Hz to avoid having the same settings, but I haven't decided what settings to use yet. It should probably reduce the vertical total to 1625 in that case to give it exactly 70 Hz, but I don't know if that helps with any monitor.

It probably can't handle 72HzMany 1920x1080 monitors can get 72 Hz, but the timing parameters usually need to be tweaked. That's why I added the "LCD reduced" option to make it easier. Using standard timing parameters with DVI or HDMI would require patching the driver, and some monitors can't handle standard timing parameters at higher refresh rates. The settings I chose work with a lot of different monitors, but some monitors might need different settings. |
