I recently connected my XBMCbuntu based system to an HDMI monitor, via HDMI. It has an Nvidia 8400GS and worked fine on VGA , even auto swiched refresh rates as needed, however on HDMI I have something strange happening.
1) When I load the XBMCbuntu GUI, I get 60hz as default refresh rate, however when I logout and load XBMC directly my refresh rates are from 50 to 53hz, and nothing of 60hz. In the Nvidia settings I can see that 60 hz is available, however in the monitor settings panel I see toe 50 to 53 hz ranges available. It seems that XBMC is using these settings. I would like the refresh rate set based on content and do not want to limit it to refresh rates such as in an Xorg.conf. I would like to have both 50 and 60 hz available at the same time for both PAL and NTSC content.
2) It seems that the screen changes . For instance if I set the display at 53 hz and adjust the screen corners , later I might find that the top of the display gets cut off. In that screen adjustment I can see it is still at 53 hz, but something else appears to be changing (Sync?). This change can happen from simply starting a movie.
Thanks for any help
