Comment 5 for bug 751735

I've the same problem.

I've two hdmi devices connected to my pc: a lcd 1080p monitor and a tv Sony Bravia LCD.
The green/ping/purple color issue happens only on the Sony TV.

It appears immediately after booting on the natty live iso or after complete installation.

I've tried many things without success:
- latest version of the intel video drivers (2.15.00)
- power on tv before or after boot
- power on/off tv
- 32 and 64 bits

I have never had this problem with previous ubuntu versions.
I've finally reinstalled maverick and all is fine with it.
