You might try the patch here: https://bugs.freedesktop.org/show_bug.cgi?id=27708#c7
If you are using a DVI or HDMI port, some TV's don't properly update their checksums for different ports if they have minor edid changes for the port. Also, some hdmi receivers/switches mangle the edids.
Thanks, that's exactly the patch I'm already using. Works perfectly :-)
I should mention that both monitors are VGA, so I'm using a VGA←→DVI adpator. And as I said before, it used to work without the patch :-)
Kinds regards, Lisandro.
