I am now having a double monitor display. My laptop is connected to two external monitors. The first one over HDMI and the second one over VGA. Can I somehowe active also the laptoop screen so that I can have a 3 monitor display.

Is this possible?

  • Is there anything in wondows default monitor options preventing you to do so ? (if using another OS, please specify which, and your GPU brand)

  • Well, it depends, as Kwaio said, about your set up... Can your mobo/GPU support this? What laptop, what OS, what GPU, internal or external drive, any mods etc?

  • Would you be able to upload and add a screenshot of the menu : "Control Panel > Display > Screen Resolution" ? (after clicking on "detect" to be sure all plugged monitors are detected)

Technically the 17R SE 7720 itself will allow up to 3 monitors (Built-in Display and 2 External Displays) to be connected in either Clone or Extended Mode and working all at once.

However, and this is the important part:

Without using Intel's WiDi technology (Drivers are available for the 17R SE 7720 in the Dell Driver Download Section) you'll be limited to using only 2 displays.

There are also suggestions about using a splitter, but, this (from my understanding) will duplicate the content where as I assume you want to use 3 monitors individually with unique content).

Also, check out http://www.notebookcheck.net/Intel-HD-Graphics-4000.69168.0.html as this claims the Intel HD Graphics 4000 has the ability:

Another new feature is the support for up to 3 independent displays (depends on how the HD 4000 is used in the laptop - maybe only with a DisplayPort / eDP) as AMD offers with theirs Eyefinity support (up to 6 displays).
