My lap top specs are down below. I already have a 21 inch Acer monitor (doesn't have hdmi), and ordered the Asus listed below in somewhat of haste as it was on sale. Last night I was having issues with just trying out the Asus alone as an external monitor via VGA. If the lap top screen was closed, it would work fine for about 15 seconds, then go black, saying out of range.
If the laptop screen was open, the Asus would work, but then randomly finick in and out with a VGA connection notice.
I bought the following HDMI cable: http://www.target.com/p/ge-6-feet-hd...m=hdmi+to+hdmi
Hoping to have 2 external displays via 1 HDMI to HDMI, and VGA to VGA in proper quality... The Acer looked fine, while the Asus was not very crisp and wouldn't completely cover the screen.
It's starting to look like I hope at least returning the monitor is feasible/not too costly.
