My laptop is an Alienware 15 R3, with NVIDIA GeForce GTX 1060, Windows 10 installed.
Every time i connect to an external monitor with HDMI-VGA adapter with the lid of the laptop closed, it sometimes randomly freezes. The screen, keyboard, etc. completely frozen. Sometimes even freezes in-game. To unfreeze, i need to open and close the lid or unplug and plugin the AC adapter again. If i use the laptop without the external monitor or with the lid opened, it does not freeze. This is a very strange seldom behavior. I've been trying to screen the problem to see where this comes from, but without any success. I am not sure its a NVIDIA problem, windows problem, etc. It passes all the Dell tests. no hardware problems that the tests cover.
Does anyone have any idea what this might be?
I had a similar issue when I booted my AW 17R3 with an external monitor plugged in the HDMI port. It was due to a conflict between the intel ang nvidia graphic card that locked up the system, so a hard shut down was required. I haven't tried it for some time since I now use a dock with HDMI.
But I think it is resolved after the new intel and nvidia driver updates.
The same thing is happening to me. It's quite strange sicen I've been using an externa monitor from almost 2 years with no problem at all...
In my case the screen freezes and the sound also stops...
I use a Dell Inspiron 15 7000 7567 - 15.6" - i5-7300HQ - GTX 1050 - 8GB
Will keep an eye on this thread just in case someone has a solution...
