FIXED! Dell XPS 15 HDMI/HDTV display

Download the latest windows updates as well as the latest dell BIOS updates.

Fixes many of the screen resolution problems we have been having.

Fixes the dual monitor NOT displaying on your HDTV via an HDMI cable.

Suggestion: Make sure to buy a QUALITY HDMI cable with the latest compatibility for todays high speed audio and video needs. I bought two different kinds and both are more than capable and compatible with todays higher speed/high quality audio/video tech.
