i have a viera too and it doesn't support EDID on vga but it does on hdmi.
i use a dvi to hdmi cable now.

I have now fixed this, here is how-
I looked at my TV's manual, and in the back amongst all the tech spec it said it supports a pc signal of 31-69khz horiz and 59-86khz vertical.
I manually changed the refresh lines in the xorg.conf file and then ran
and this time I had supported modes everything is functioning fine
Hope this helps people that cant auto detect edid info
figured it out yet!?!?! - geant90 - 2009-12-14 23:54
Has any one figured it out yet? My EDID reports it dosent do any 1080p or 1080/24p ive tried everything and i fail, am using ubuntu karmic im bout 1 step away from slaming this damn htpc into the wall
i got it! :) - geant90 - 2009-12-15 01:06
hey your tutorial always worked fine, but it is not listed in xbmc. how can i get all my resolutions Modeline so i can select within xbmc and have it change with the media being played. and does anyone kno how to calibrate the overscan im not sure if the lines in the corner should b in the corner of the screen or should i have it right outside of view and only see the arrow. help me i want perfection
I can see its 24hz and my tv reorts it but xbmc report 1920 x 1080 @ 50 hetz so idk what to do to get it acurate to only the settings i input, also with the over scan, shouldnt there be none? No over scan with hdmi i would hope so movies that are for example 1820 x 800 are now 1826 784 so arent i losing quality, idk im curious help meo ut please.

Adjust the settings on your TV to turn on 1x1 pixel mapping.

On some displays EDID information is not correct, so this cannot always be expected. For example I have one tv, that has 1280x720 panel, but none of the 720p modes is compatible with EDID infrormation fetched from the tv and only smaller resolution and 1080i modes are valid. So I have to just pick one 1280x720 mode with suitable refresh rate and try that. Then add

Not all users use panel tv. There are also those using projectors and/or rear projection tv models. It is not rare that some portion of panel's pixels is outside of the viewable area. This is true at least on some rear projection tv models and still a nececcity (at least in my opinion) with any projector, because the edges of the picture will never, or rarely be straight and/or geometrically correct. And that's why screens usually have black bars on their edges. So sometimes it really is necessary to get for example 1912x1072 resolution centered for 1080p panel.
This is also why I think that it is a huge problem with projectors, that have 1920*1080 panel and the material is 1:1 same resolution. Usage of overscan then always results to scaling material onto another resolution. Or some portion of material is not viewable. With movies such cropping is not necessarily a problem, as at least movie studios do cut (or at least did before) movies so that there is no relevant material on possible overscan area. But for example with XBMC user interface fills whole panel and there is no option for adding any kind of padding around the interface (or is there, I'm relatively new to XBMC, but have used other htpc interfaces in the past)
Fortunately though this is not anymore as huge problem, as it was with CRT projectors (the edges of picture are virtually always unusable), but then again, they were/are analog devices and can usually use a bit larger resolution than source material is. So adding pixels to the edges weren't such a problem. But at least I like to use black bars on edges of the screen still with LCD projection and I think that there are some others too.

Has anyone tried this with 9.1.1?
- idlehands - 2009-12-29 19:08
Ok, I've been reading this thread, and all the linked threads and I'm having a fair bit of issues getting correct video resolution with xbmc and tv.
its a phillips projection scan, that according to the manual supports:
I tried reading the edid with the read/parse edid functions over hdmi and got nothing valid from the tele.
i was going to manuall create modlines, but without the horizontal and vertical refresh i think i'm sol on that. Anyone have hints on what I should try next?
this is on xbmc live camelot, installed to a standalone drive

Just lost my xorg.conf when upgrading to the final 9.11, needed to add this else all my previous settings did not work!
