Windows – Second Monitor Not Recognized After Boot on New Laptop

external displayhdmilaptopwindows 7windows 8.1

I just bought new Asus laptop model N750JK. I've tried to connect it to my external monitor via HDMI port (HDMI->DVI adapter). The second monitor displays image on the screen when I start the PC and it's there until Windows desktop is about to show (when windows logo dissapears). I can't get it to work no matter what. (I've tried detect method in display properties, without success).

Then I've downloaded latest Intel HD 4600 drivers and it worked. Image was showing on laptop AND external monitor. But when I made the restart of the laptop, the situation was the same as before. Second monitor couldn't be recognized when in windows.

I'm using windows 8.1 and I've tried on windows 7 also.

Model: Asus N series N750JK

Laptop graphic card:
Graphic card: Intel HD 4600 (this one is primary – can't change), Geforce GTX 850M.
I also tried with HDMI – HDMI cable via another monitor and it has the same behaviour as described above.

Any help will be much appriciated.

EDIT: I would like to know from first hand if somebody has the same laptop as me (or at least same integrated graphic card), if experience the same problems as me..

EDIT 2: I've tried Linux distribution (FEDORA), and it WORKS like a charm right from startup!

So what could be wrong in windows? It seems this is not hardware issue..

From your description it sounds like it's a software/driver issue, as the display is receiving input up until the point where the driver is loaded by Windows.

I would suggest the following:

  • Try Win + P and set it to extend desktop to see if that has any effect. Could be Windows is simply not sending any output to HDMI.
  • Try reverting to the default driver (uninstall the HD 4600 driver, remove the GPU device from Device Manager and then reboot). Test if anything is changed, then install the latest driver.
  • Try disabling the Intel HD 4600 in BIOS, if possible to see if this helps the issue.
