I am really scratching my head here. I have a Pioneer PDP-435FDE screen connected through HDMI to a Zotac ZBox ID-41 (ION2), running Xubuntu 11.04 and XBMC and NVidia drivers 270.24. The system is stuck at 50Hz. I know the screen can handle 60 Hz, had it working at 60Hz with a cheap mediaplayer setup before.
- In NVidia Setting, I can select "60 Hz", but this doesn't do anything (the Pioneer display does characteristic flashes when changing refresh rates, but they don't happen here - also the "Flat Panel Information" in the NVidia control panel remains at 50Hz).
- In XBMC, I can only select "50 Hz", "51 Hz" and "52 Hz" as refresh rates.
I tried to follow this guide, without results: http://forum.xbmc.org/showthread.php?tid=70068
From the instructions in the thread mentioned above, I was able to extract the following EDID modes information:
My xorg.conf looks like this, with mods from the thread before:
Commenting out the "metamodes" line above results in XBMC not offering any selection for the refresh rate at all!
Long plea for help:I hope anybody can help - because 60Hz is the key to judder-free playback with this screen: while 23.97 Hz 1080p input is not supported, there is an inverse 3:2 pulldown mode for 60Hz input, the display removes the frame repeats, gets to 24/23.97 frames and displays at 72/71.91 Hz. Convoluted, but works great in practice.
Short version: I need 60 Hz, please help!
