Please help. I just purchsed a new Sharp Aquos HDTV and have connected my laptop to the TV without any issue. When I go to attach my desktop computer using the same HDMI cable through the HDMI output it recognizes the TV as a viable monitor (i.e. it says Sharp HDTV as an available monitor) but when I choose, extend, duplicate or projector only none of them produce an image on the TV.
I am assuming that it is an issue with a setting or my graphics card which is an ATI Radeon HD 5650.
Any assistance would be helpful.
