I have a Toshiba laptop and I cannot get it to connect to my Panasonic VT25 plasma tv through HDMI. I know that the cable works and that the connections are good because I have connected my laptop to my Sharp LCD tv with no problem. Also my PS3 is connects and shows on the VT25 through that input without a problem. I thought the problem is with the resolution but the specs on the VT25 say that its resolution is 1920x1080. Does anyone have a clue how to fix this?
