Default No H&SDTV TvStandard support 8174 ... WTF?

The output from startx shows that 8174 supports no SDTV or HDTV modes whereas 8676 supported a range of them.

What's the story? This makes it impossible to use 8174 for H/SDTV.

Please post bug reports (one for 1.0-8174, and one for 1.0-7676) that support this assertion.

Thanks,
Lonni

Attached are two Xorg.log files resulting from the execution of 'startx -- -verbose 5 -logverbose 5' over 8174 and 8676.

You will see that the NVidia driver reports that it does not support any but NTSC and PAL modes in the 8174 build.

Is there something more you need me to do to demonstrate the assertion?

Colin.

I have posted a single bug report containing the output of nvidia bugreports for both 8174 and 7676, along with the two logs which actually provide the evidence you solicited here.

So, as the logs show and the bugreport formalised, 8174 reports itself as being unable to provide the HDTV and SDTV standards.

I suspect this goes some way to explaining why no possible HDTV or SDTV resolution is accepted by 8174, which reports that the resolutions are not valid (or is it legal) TV modes.

I've received your bug reports, however please don't send information to linux-bugs@nvidia.com if you've started the thread here. It just serves to confuse anyone else watching this thread, and slows down my response.

Please try adding the following option to your X configuration and test 1.0-8174 again:
Option "IgnoreEDID"

Thanks,
Lonni

Oh, ok, sure. I didn't know that 'send a bugreport' was satisfied by 'post here'. Now I do.

Done. Xorg.log reports:

(II) NVIDIA(0): Not probing EDIDs.

But does not include any additional TV Standard lines. Specifically, it still does not report supporting HDTV or SDTV formats.

Regardless of what is reported, is the picture on your TV correct for HDMI with IgnoreEDID?

Thanks,

No, there is no picture on my TV, because I cannot specify any modeline which 8174 doesn't reject, as being not a valid TV mode.

The only way I have discovered to get a picture on my TV is revert to 7676. This, after quite a bit of flailing around trying to find a modeline to suit 8174 (but none does.)

Can you please test 1.0-8178 and see if this is resolved?

Thanks,

Thank you, yes, the newer driver accepts the same modelines as the old, it seems.

So this problem is resolved.
