Hi,

Parts of the screen are displayed outside the visible area on my LCD TV using
the HDMI output on my Radeon HD4550. In some modes I can see half the top menu
bar. In other modes it's completely off the screen.

I have tested with:
radeon driver
radeonhd driver
Fedora 13 stock kernel 2.6.33.4-95.fc13.x86_64
kernel 2.6.34.1
kernel 2.6.35-rc5
nomodeset boot parameter

They all give the same output.

The driver also has trouble finding valid modelines. I can force it into higher
resolutions with modelines I got from windows with powerstrip but they also
display the borders of my desktop outside the visible area.

Changing the resolution takes almost 30 before an image is displayed on the TV.
Which would indicate the TV has a hard time understanding the Radeon output.

regards,
Martin
