you've got two hdmi inputs on that TV and more. what you don't have is a normal computer connection. rather than trying to add that to the TV, just buy a video card for your computer that has a connection for the cables the TV will accept.
I'm interested in the Panasonic TH-42PX77U plasma. It does not have a PC input however.
I know its possible to add HDMI inputs to certain TV's...can one add a PC input to this TV? If so, any recommendations for PC inputs or recommendations where to buy one? Thanks in advance.
