I just thought I would pass this along. I was going to post a question on this subject but I now have the solution. I live in SW Florida where even in the winter things can be pretty hot. I parked my car facing due South the other day on a very clear day. For some reason the heat on the dash caused my information display monitor to get all pixilated. I have had the top and bottom dim from time to time (on hot days). I thought it would reset after cooling or a couple of starts but nothing! I then decided to disconnect the ground at the base of the drivers seat thinking it would reset it. That did the trick.

that is very good information. Our display has done that (the top and bottom) for the past two years, and 2 weeks ago was at a Porsche dealer to fix the coolant distribution pipes, and my wife picked it up and the display did not work at all. Of course, they had no idea and it wasn;t there fault!! (as they said) even though it had been working normal for a long time. They changed out the LCD with one from another they had lying around, and it has been working ever since. we'll see.

Which ground did you disconnect? Just the battery or is there something else I am missing.

and thanks for the update.

I had the same pixelated display problem and removing the battery ground for a few seconds worked for me as well. As an EXTRA bonus, my TPMS "Workshop Required" warning also went away and I have my TPMS working again!!! I am so happy that I am not going to spend the $2,000 the dealer quoted me for a new display and new tire sensors.

Pictures attached for posterity.

Just so I am clear, this ground is located where? Also was the ground permanently detached or was it detached and then reattached? I have the same issue with the pixelation on my multifunction display, but would like to be certain of the procedure to follow.

He is just talking about disconnecting the negative lead from the battery for a few seconds then reconnecting it.
