Thanks for the replies!
Tiddles88 - I'm not exactly sure where to check via the graphics control panel (and my googling of Catalyst Control Centre didnt turn up anything that seemed to be related to my system, but if you have more information i'll be sure to check it out). I did ensure the TV and computer were both set at 1080p/60hz.
Andrew - I had the input HDMI 2 "name" set to PC, but i assumed that was just a description. The HDMI2 is labled HDMI/DVI, so I moved the cable box to that one and the HDMI1 to my HTPC (and changed the description to PC). I have not seen an option for "no overscan" on the TV.
HOWEVER, changing the HDMI port seems to be working so far. I have also noticed that utilizing the HDMI 1 port (i.e. the NON-HDMI/DVI port) has enabled me more options with my picture. so maybe that was the issue all along? Ive een on the computer for about 15 minutes and have not seen any issues...
I'm not really sure why Samsung has labeled the second input that way - its definitely an HDMI port (not a DVI port) but the fact that it has less picture options is weird to me ...
Assassin - thanks for the replay, but when I ran the hotfix, it said it was not necessary for my computer.
Thanks again for the help.
