I’ve tried a bunch of different things to get the Nvidia driver to work on my Panasonic TV, but It won’t correctly read the EDID and it also won’t accept non EDID modes, so I’m in a bit of a pickle. Here is my Xorg.0.log collected using startx – -logverbose 6:

If you want to use your own modes, the ModeValidation override you want is AllowNonEdidModes, not NoEdidModes (which has no effect since there’s no EDID).
It’s surprising that there’s no EDID, though. Do you have a different cable you could try? DVI and HDMI monitors are required by the specification to provide an EDID.
Thank you so much!
I spent hours on this after upgrading from a previous driver version (275.09.07) that just read the ModeLines without needing “AllowNonEdidModes” to be set. It was driving me crazy!
