Ok, here’s a bizarre problem.

My previous PC crashed, so I bought a Dell Inspiron desktop. On the old computer, I had connected an HDMI cable from the PC to the TV, and I was able to mirror to the TV.

With the new PC, I connected it to the TV using the same HDMI cable, but the PC doesn’t detect the TV, although the TV ‘Inputs’ screen shows a blue icon for HDMI 3, I suppose indicating some kind of connection, but the TV screen displays a ‘No signal’ message. I would like some help with this issue, but there is a more immediate problem.

While trying to get the PC to mirror to the TV, I somehow messed up the displays. When I plug the HDMI cable into the PC, the PC monitor goes black and stays that way until I unplug the HDMI cable from the PC. My assumption is that the PC is using the TV as the primary display, even though nothing displays on the TV except the ‘No signal’ message.

Help!

Thanks,
Richard
