few errors at boot on a dell optiplex gx280; how to stop the errors?

[floppy]

Hello,
I booted a DELL Optiplex GX280 (/0G8310, BIOS A04 02/09/2005) with TCL + xorg76.
So far, everything is fine.
Only few errors (see the dmesg.txt) which can be partially seen at boot

How to stop this? (dont seems to distrurb really; is only not very clean).
If any Idea is proposed, it would be great.
In parallel, I will further search on the web for any solution.

You should just ignore those, many screen manufacturers have such invalid EDID embedded in the screens. I don't think you can silence them with a parameter either.
