Default Re: Sharp Aquos EDID FX 5700LE

I think what you need is: NoEdidDFPMaxSizeCheck

I wish there was a "NoXXXCheck" option that disables all superfluous checks in one go and keeps working across versions.
Every time I upgrade the drivers I have to tweak the configuration to circumvent the extra checks added in that version. It would be nice to have the possibility of just obeying what is written in xorg.conf (modelines, mainly) instead of second-guessing....

Just copy and paste all "No....Check" options from the readme file into your xorg.conf, I would say...

Go through this thread and you'll find a combination of a modeline at twice the frequency that SHOULD be required for 1080i and settings that stop the driver from rejecting it.

Once you have 1080i working, you should be able to use similar settings to get a native resolution modeline working.

I think the problem here is that nVidia, so far, has been trying to treat anything connected by DVI as a DFP. If we were talking about the average flat-panel desktop monitor, the assumptions that have been made are valid. However, a DVI-connected TELEVISION is a different critter all together and should be treated as such.

His problem does not look like a problem with frequency.
It is a problem with resolution. Because the EDID is turned off, NVIDIA assumes the panel is 640x480 and discards all modes with higher resolution than that. The problem is to find the "check" that does this.
(in another thread, an NVIDIA employee wrote that this unreasonably low default resolution is there to avoid damaging hardware. however, he has been unable to provide an actual example of DFP hardware that would be damaged by a too high resolution)

Can you try the same setup after 'startx -- -logverbose 6' and post it?

Better yet, NVIDIA should make this part of the code Open Source. There can hardly be any company secrets in the part that makes the configuration decisions and handles the Options from the xorg.conf file. The code that decodes the EDID, decodes the Options and then makes the initial configuration decisions (devices, what to assign to what, what modelines to use etc) should be open source- then that part of the code will be greatly improved because it can be scrutinized by hunderds of guru's around the world under Real Life circumstances. The way the code is being maintained now gives the strong impression of heuristics that are mere guesses: Maybe this will work? Nvidia should become tired of maintaining this part too by now: it never seems to completely work. Sure, it works for (no idea... 90%?) and 9% is using work arounds -- if not more -- heavily using all kinds of override Options, but every time anyone has to manually tweak their xorg.conf with those override options the real problem lays in this part of the code imho (not to mention the amount of time that goes into this tweaking world wide).

Does this also fail in the same fashion with 1.0-9742 ?

Has this "resolution larger than native" check been removed in 9742?
