I am looking to put my lap top through my plasma but I also want to watch stock information running from another computer. It would be purely from me being lazy and not wanting to turn my head is it possible? If it won't work with my current plasma 42" TH42PWD5, will it work with another? I need to get one for my home so I may just swap the one in my office for one that can do this. Any advice would be great!!!
