Bought my Mits. 55" RPTV 2 yrs ago (fall '02). Mits then had a "guarantee" or "promise" of "future upgradability" due to any technology changes. This was 1 addt'l factor in why I bought the Mits. I have several component hookups on it, but no DVI or HDMI. I have e-mailed them 3 times to ask w/n my set WS-55511 can by "upgraded" to support a DVI connection. I have not received any response at all. I think they are ducking me on their promise. I went back to the seller (HH Gregg), and they simply don't know and gave me a 1- 800 # that is supported by a computer. Anyone have any similar experience? Anyone know whether DVI can be retrofitted in my situation? Am I just sol - and need to buy a new set like everyone else? I'm happy with my PQ, but still wonder whether I'll be missing anything connecting my 2910 with component rather than DVI. Thanks.
