RE: Custom Resolution Utility (CRU)
NCX used timing parameters that went over 165 MHz, which requires HDMI 1.3 support or the pixel clock patch. The patch has no effect on anything older than the 5000 series, and older cards don't fully support HDMI 1.3 either. There isn't a way to get past 165 MHz with your video card.

There isn't much room for tweaking at 75 Hz, but you might be able to get 72 Hz working. First, I would check if the horizontal parameters are causing the problem by leaving the horizontal at standard and adjusting the vertical so it looks like this: H: 1920 48 32 80 160 2080 V: 1080 3 5 12 20 1100 If that doesn't work, I would leave the vertical at standard while adjusting the horizontal so it looks like this: H: 1920 32 40 48 120 2040 V: 3 5 29 37 1117 Some monitors will only work with both horizontal and vertical reduced, which "LCD reduced" already does. You can also try reducing the horizontal a little more while adjusting the vertical like this: H: 1920 24 32 32 88 2008 V: 1080 3 5 10 18 1098 If none of those combinations work, it might not be possible to get 72 Hz below 165 MHz with that monitor. At 75 Hz, there isn't much you can change. If "LCD reduced" doesn't work, all you can do is try reducing the horizontal more while adjusting the vertical like this: H: 1920 24 24 32 80 2000 V: 1080 3 5 12 20 1100 |
