I've tested the ION on a couple of different displays around the house
all via the same HDMI cable, here are my results (all of these displays
support 1080i and 1080p):
Sony Bravia 46" HD TV (KDL40V2500) - Tearing <--- This is the one I am

Sony Bravia 32" HD TV (KDL32SL130) - Tearing
Asus 22" Monitor (VH222H) - No Tearing

Screen 0: minimum 320 x 175, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
1920x1080 50.0* 51.0 52.0 53.0
1680x1050 54.0 55.0
