Not sure what HDMC is.. but the HDMI on my 732 will accept 1080p signals... I got a steal on mine at HHGregg for $1950 :D :D And honestly, I don't think there is another TV out there that can smoke this 57 incher, except maybe the Diamond series.....
The 731 is a good set... but I have the 732 and it is much much better. The 732 has the PerfectColor and PerfectTint, as well as Deep Field imager, and another component input. I think for the difference between the 731 and the 732, get the 732. Just be aware what you are buying is what you...
