How to solve the problem with connecting an external monitor to a laptop on Windows 8.1?
There is a laptop "HP ENVY m6-n012dx" and a monitor "DELL U2311Hb". Their resolution is the same - 1920x1080.
Windows 8.1 (64-bit) persons. and the updates are all worth it.
Integrated video card - Intel HD Graphics 4600. The
drivers for the video card are now the latest - Version: 15.36.14.64.4080 (Latest) 01/12/2015 . I also tried a diver with off. laptop site Version: 10.18.10.3368 2014-03-10 I
connect via the cable "HDMI - DVI-D dual link (Viewcon VD078-3)".
But when connected, the monitor is not detected ... it just goes into power saving mode. I pressed the button that calls the "Transfer to Screen" panel ... and there are different display methods ... "Duplicate", "Expand" ... but to no avail.
Everything is ok with the cable and the monitor, I checked both on the PC and on the other laptop. I thought maybe something was wrong with the laptop...
Then I decided to check... I wrote down Ubuntu 14.04 on a USB flash drive and started it on my laptop... the second monitor picked up instantly (even the OS itself had not had time to boot). So the laptop is ok too.
I started experimenting further ... and it turned out that if I reinstalled the drivers for the video card, then at the end of their reinstallation (when the laptop screen goes blank for a second, probably to apply some parameters), both screens turn on and everything works fine ... but after a reboot , the external monitor is not detected again.
So I ask for help from experts ... what could be the problem and how to solve it?
And then every time you rearrange the driver for the video card so that the monitor works .... it's not cool at all.

Faced the same problem on ASUS N56VZ with Samsung Syncmaster 204B monitor. Connection is also by HDMI - DVI-D cable. And I noticed that everything happened after one of the updates (unfortunately I did not track which one). On bourgeois forums they write that the problem is in the chipset and firewood. Allegedly, they are very demanding on the connected peripherals, and the slightest deviation from the ideal leads to the observed bathurt. I postponed the struggle with the monitor for an indefinite time, connected it to VGA.
By the way, the Acer M342 projector is connected with an HDMI-HDMI cable (the third of the specimens tested) and it works quite well.
