Windows 7: 2nd monitor screen is blank

01 Sep 2013   #11

Windows 7 home premium 64 bit

I've read about my video card's 'standard Display Connectors' which are: One Dual Link DVI-I, One Dual Link DVI-D, One HDMI, One DisplayPort.

I've noticed what VGA adapters i'am actually using are one DVI-I(single link) and one DVI-I(Dual link) which explains the reason why the second VGA adapter(DVI-I Dual link) doesn't plug in completely into the DVI-D port so that's the real reason why my 2nd monitor isn't working properly?

However i'am surprised that my VGA adapter DVI-I(single link) inserted into the DVI-I Dual link is working properly

There is nothing you can do to the card. Maybe a little reading up on how DVI works might help,

Digital Visual Interface - Wikipedia, the free encyclopedia

and for what is on the card,

  • DVI-D (digital only, single-link or dual-link)
  • DVI-A (analog only)
  • DVI-I (integrated, combines digital and analog in the same connector; digital may be single- or dual-link)
The DVI-D and DVI-I connector provide (via additional pins) for a second data link. This allows resolutions up to 2560x1600, which are supported by many add-on graphic cards. A connector with these additional pins is sometimes referred to as DVI-DL (dual link).

I have dual monitors set up for extended displays. The monitors are correctly positioned in the virtual display. When I move a window to the second monitor, it disappears from monitor 1 but doesn't show up in monitor 2 - that screen is black. Thanks

Monitor goes blank before log-in screen, stays off
When I boot-up my computer, it takes about 2 seconds longer for the monitor to turn on then usual, and right before the log-in screen the display will disappear, and stay off. The PC continues working normally, as far as I can tell. What precluded this issue? Why, I haven't the foggiest....
