There are many resolutions in market but we can store small portion in EDID DTD.

I select several recent popular resolutions from wikipedia page;

I have an issue with KVM when selecting display resolution
in guest OS. After short research, I found a post about
supporting EDID in April, 2009 by Brendan Trotter on boch-developers ML.

There is no real patch and it was not adopted.
I'm trying to reproduce code on current and made it work.

There are a series of patches.
0001: Brendan's suggestion
0002: format comments, add header line
0003: format comment(cont) wrap 128 chars.
0004: add high and wide resolution
0005: split low and high resolution bios
0006: set high resolution bios as default

You can also see it on github.com
that is one on top of cvs repos.


There are some FAQ how support large resolution.
and it suggest a manual setup on xorg.conf in guest OS.

My work may make it obsolete because user can select resolutions
with OS's configuration utility in recent OS.
