Hi,
I purchased three of this model of computer:
http://www.ebay.com/itm/Gateway-DX4870-UR368-Core-i7-3770-6GB-500GB-DVDRW-USB-3-0-Windows-8-Desktop-PC-/290960465524?pt=Desktop_PCs&hash=item43be985e74

(Intel HD Graphics 4000)

However, it does not drive the 23" Acer LCD monitor that I have.

My neighbor, brought a small LCD monitor which works.....

I tested the 23" monitor on my i7 laptop (Intel HD Graphics 3000) and it works just fine.

What could be the reason for this?

When I say the 23" monitor does not work, I mean, the blue light just stays flickering, does not turn solid blue.....

Yes, the monitor has more than one input, HDMI(2) and VGA(1), however, when I move iot to the laptop it auto recognizes the VGA and works just fine, as soon as I plug it into the desktop, it goes into "flickering blue light", which, I am told is standby-mode
