14:00 <lekernel> unsurprisingly enough, the EDID standard is a piece of shit. there are no fewer than 3 ways of specifying such basic things as the number of pixels in each dimension ...

14:04 <wpwrak> what ? no vendor extensions for more formats ?

14:08 <larsc> edid has grown over the years

14:08 <larsc> back in the old days there were only 4 modes

14:09 <larsc> the standard tells you how to specify your modes and still be backwards compatible

14:12 <lekernel> can I ignore GTF? since I guess the preferred modes should be "detailed timing description" anyway

14:13 <lekernel> the GTF "reference" implementation is written in Excel, lol!

14:13 <larsc> if you don't want to support ancient hardware/software you can

14:14 <larsc> linux will e.g. read all possible mode sources and put them in one big list

14:18 <larsc> it is probably even fine to go just with the cea modes, no need to specify any timings, just list the cea mode id

14:19 <lekernel> ah fuck, there's cea too

14:19 <lekernel> grrrrr

14:22 <wpwrak> #4 ? :)

14:23 <larsc> I think there are 6 different ways to specify a mode

14:25 <larsc> but not each mode can be specified in all the different ways

14:28 <lekernel> established timings, standard timings, detailed timings, cea extensions - what are the other 2?

14:31 <larsc> inferred timings and cvt

14:33 <larsc> both seem to be in the detailed block though

14:34 <lekernel> and standard timing can be either GTF or secondary GTF

14:34 <lekernel> so this makes a total of 7

14:36 <lekernel> what an imbecilic standard

14:38 <larsc> would be good if there was a program which you hand a mode table and it spits out the correct edid

14:42 <wpwrak> you're probably want to classify by age. if you support some truly ancient mode, also use the ancient encoding, so that ancient equipment can interoperate

14:49 <lekernel> ah, and of course: http://lxr.linux.no/linux+v3.10.9/drivers/video/fbmon.c#L65

14:51 <lekernel> first two are CRTs though, so I guess I can ignore

14:56 <larsc> this is the file you want to look at http://lxr.linux.no/#linux+v3.10.9/drivers/gpu/drm/drm_edid.c#L89

14:57 <lekernel> "Samsung SyncMaster 205BW. Note: irony" :))

14:58 <larsc> I know

20:45 <ysionneau> ahah

20:46 <ysionneau> syncmaster having sync problems, nice :)

21:31 <wpwrak> ASyncMaster :)
