Now my desktop extended to 2 monitors: laptop and display connected to laptop via hmdi.
I decided to add the 3rd monitor and connected it via d-sub to laptop.
Windows 7 detectes it in Control Panel\Appearance and Personalization\Display\Screen Resolution
.
I select the 3rd monitor and choose Extend desktop to this dislplay
. Click Apply
, Save Changes
. But Multiple displays
field revert itselft to Disconnect this display
. And there is nothing on the 3rd monitor.
My laptop video card is Intel(R) HD Graphics 4000
. 3rd monitor model BenQ FP71G+
.
Lapton model name is samsung NP300E5X-A07RU
Operating system: windows 7 ultimate x64
Seemingly it's possible with my video card, but question is how to do it?
pabam
, and old 2 monitors turn to black and then return representation. And on the new monitor nothing changed.
