Hi, going to buy a 42" plasma soon... I understand that HDMI/TV support is very important. However there are some plasma's that have 1024x1024 resolution and some that have 1024x768 resolution. Will a screen with 1024 vertical display better HDMI signals than one with 768? Or will both only show up with the same 720P HDMI? And also what about displaying 1080i HDMI?
