Hello, I am NOT tech savey but I should be able to do this. I have a Toshiba L755 laptop with an hdmi port, I'm trying to connect to a Sanyo Plasma TV which has 3 hdmi ports. When I bring up the "screen resolution app", with the hdmi cable connected to the computer and hdmi port 2 on the TV (TV set to port 2) it "can not find a monitor". It will find a VGA monitor when the VGA monitor is plugged in. I see something about a desktop management tool, is there one for Laptops too? The computer uses Windows7 Home Premium. The hdmi cable is new, actually the second one I've tried. The hdmi ports on the TV work, (I plugged the TV cable box into them and they function). Is there some way to test the hdmi port on the computer? Do I need another gadget? I am at a loss and totally stumped.
