If I ensure my new TV...

can have overscan turned off via HDMI
has native resolution of 1920x1080
is 1080P

... can I simply change the resolution of my media PC* to 1920x1080p and off I go? Or will I have issues? Fuzzy fonts?

Where does 1:1 pixel mapping come in? Is this irrelevant in my above situation?

Thanks again smile
