Hi there,
i have a new Inspiron 7347 that can't show external displays. When I connect an external display it is identified correctly under >Screen Resolution, but the external screen remains blank. I have checked with other displays (same result) and connected other PCs to this display (all fine), so I am sure it is the laptop not the external display.
i have updated video driver and BIOS, and changed the HDMI cable, with no change. I cannot think what else could be causing this. Getting extremely frustrated - an ideas why this is happening?
Thx.
