My just arrived XPS 15 9550 which I have updated to the currently newest drivers (BIOS, Chipset, Video, Audio) does not detect any external display via HDMI. It says no external display has been detected. My previous Dell notebook had no issues at all.
Any ideas what the problem might be and how to fix it?
Many thanks in advance!
Had the same problem and this was my solution. Connect to your external monitor. Right click on your desktop then select the intel graphics control panel. While on the display tab, change the resolution of your laptop to a lower resolution. Probably the same as your external monitor. dont apply. Just wait for your external monitor to work then bring back to your normal resolution.
Hope this works for you.
This partially worked for me. Using this method, I can only put the external monitor as "extended" desktop. Putting it as clone or sole display doesn't work!
you have a key on on your keyboard that should say CRT / LCD you should be able to press that with the fn key and it should ask if you want to duplicate or use just the monitor or the lcd screen and it should automatically adjust your resolution. from what in saw on this laptop it should be the FN + the F8 key to do this.
I tried that couple of time Miie and it doesn't work. The resolution is not an issue because I can extend the desktop. And I even extend then try to clone or use my external monitor as primary display after manually setting the monitor resolution in Intel display application.
HAVE THE SAME ISSUE. the only way i have resolved it is by rolling back the HD 530 driver to the one from October 2015. its sad but Dell has pushed an Intel HD Driver without understanding how it impacts people using any type of HDMI device. In my opinion only, very poor integration testing.
Go to Dell's product support. put in your service tag. then use the "find myself" option. go to "video". go to the Intel HD driver section. go to "other version" - its a small link in the bottom of this area. you will see the one from October or November. they do work and allow you to connect an HDMI device.
note this issue only happens with the latest Intel HD update when an hdmi device is connected for me.
Really stupid but what I found worked was when I went I removed HDMI and then reconnected. I was also in the Intel HD graphics control panel (right click on desktop) where there was a Detect button which wasn't doing anything, but then when I re-connected HDMI everything came to life.
