Regarding the refresh problem: I begin to suspect that the Intel chipset just does not support 24p mode. When I read the EDID values I get the following result on my Panasonic 42G20:
I know my tv has more valid modes, last week I tried an Nvidia card and it gave me the following results:
So I know the EDID information can be read from the Panasonic but it looks like the I3 IGP doesn't support it or something.
