Hi, I purchase Dell XPS 17 (L702X) laptop last week. I also buy new mini display port adapter for viewing laptop videos on external monitor. I try it a lot but it makes problem during connectivity. i never seen anything on external monitor after making its connections with the external monitor. I tried to use DVI or VGA port for this connectivity but it makes problem for connectivity. the monitor goes to sleep for lack of a signal. Sometimes it also connect properly but when i try to set the external monitor resolutions to 1920*1080p, it makes problem. It works well with the 1280*1024 pixel. Please help me to fix this complex issue. Thanks for any help to fix this issue.
