The set up is MCE2005; Nvidia 6800 with latest drivers set to output at 1024x768 @ 50Hz. The display is a Pio 43MXE1 set to FRC mode 2. When I check the refresh rate using the display button on the Pio's remote it correctly shows 50Hz. But if I check it when watching TV in full screen mode using MCE2005 (Avermedia A800 USB) the refresh rates shows as 60Hz. There is some jerkiness on pans which suggests the TV picture could be 60Hz, but how can this be if the graphics card is set to 50Hz? Suggestions welcome.
