External Monitor shows "1|6" and my laptop display is "5" – what is this?

Solution 1:

I also had this exact problem. It is for sure related to the Intel drivers. I have a Dell M3800 and went and downloaded the drivers from Dell (they are much older) but it worked. I made sure to rollback, select specific drivers and installed by pointing to the extracted files.

More detailed steps (my problem came back after an update so I wanted to write more about it):

  1. Download https://downloads.dell.com/FOLDER03173279M/1/M3800_Video_Driver_7C6X2_WN32_10.18.15.4248_A00.EXE
    Warning: it is almost 200 GB; it will take a while.
  2. Run it and extract it to C:\dell; you may need to install it too
  3. Open “Device Manager”
  4. Update driver
  5. Open Properties of the Intel 4600
  6. Click “Update Driver”
  7. Select “Browse my computer”
  8. Select “Let me pick from a list of device drivers”
  9. Select the older version, 4248

Others have noted that Windows Update may push updates for the problematic Intel driver(s).

Solution 2:

I think I have solved it by removing Hyper-V (came default with Win10 Pro).

I'm running windows 10 on a Lenovo T540p laptop and had as many as 7 displays showing up at one time. I ended up removing Hyper-V due to something else (Xamarin development), and noticed my screen blinking once. And this fixed it :)

After this I could both open Intel HD Graphics Control Panel, and install updated drivers. Didn't even need a reboot.

Solution 3:

I had a very similar issue, where I had my laptop connected to just one external monitor, making it 2 monitors in total. At a certain time, the external display was mirrored instead of extended, like it always was and in the display settings there were in total 6 displays showing. After checking, I realised that there was a Intel Display driver update on the windows update history, around the same time.

So I:

  • Went to the device manager;
  • Searched and selected the Intel graphics card, under 'Display Adapters';
  • Clicked on 'Properties' on the context menu and selected the 'Driver' tab on the pop-up window;
  • Selected the option for 'Roll back Driver...', clicked yes when prompted;
  • And after a mandatory reboot, issue got solved.
