[mythtv-users] OT: Idea for possible workaround to stop bogus EDID data from messing up MythTV

Thu Oct 11 17:55:19 UTC 2007

I have a Olevia LT26HVE LCD TV, that I believe is providing bogus EDID
information to my video card (xdpyinfo reports the screen size as
40x30mm: wrong size, wrong aspect ratio).

Assuming that the LT26HVE is dumping bogus EDID, how crazy would it be
to break off pins 6 and 7 on my DVI cable?

According to http://www.interfacebus.com/Design_Connector_Digital_Visual_Interface_DVI_Bus.html
pins 6 and 7 are  DDC Clock [SCL] and DDC Data [SDA], respectively. I
believe EDID information is transmitted on the DDC.

Does anybody know what else is transmitted on the DDC?

Would that stop the bogus EDID? Would my TV freak out? Would my
computer catch fire?

Has anyone else tried it? I'm happy to sacrifice a DVI cable, but not
happy to sacrifice a computer or LCD TV.

Just how crazy is this idea?
