I just bought a Dell 13z 5323 notebook running Windows 8, and connected an HDMI cable to a Panasonic TV, only to find that nothing is shown on the TV. I know for a fact that both the cable and the TV work (the HDMI output works with another notebook).
The graphic card is Intel HD 4000, and according to Dell's website, it is up to date.
When I plug in the HDMI cable, the notebook's screen flickers and then goes back to normal. The TV is shown as a recognized device, but nothing appears on the TV.
Thanks in advance.
