Intel hd 4000, windows 7, triple monitors (DVI, VGA, HDMI)

graphics cardintel graphicsmultiple-monitors

I have a Core i7 3770k on Asus P8Z77-V LK and three monitors (actually one of them is TV). Two monitors were connected via DVI and VGA, I tried to connect third monitor (TV) via HDMI but it didn't work.
It worked as expected when I was using any 2 of them, but I still need 3 simultaneously.

I don't think that this is a hardware problem because everything works on Linux (3 monitors simultaneously).
I have updated all drivers, windows, BIOS but the problem isn't solved yet.

Pls help).

Best Answer

The gfx card will only support 3 displays in Windows 7 if -

  • If two of the displays are DisplayPort* monitors
  • If one of the displays is an Intel® Wireless Display (Intel® WiDi)
  • If the built-in display is an Embedded DisplayPort1 (eDP) not a LVDS
