Why can't I get dual monitors to work?

post #1 of 6
Thread Starter 
My graphics card is a AMD 7870 with 2GB.

Monitors
Yamakasi 27" DS270 2560X1440 (Dual link cable)
Asus 27" VE278 1920X1080 (HDMI)

When I first installed my new DS270 a few months ago, dual monitors worked, the very first time I connected the DS270 and turned it on after booting up with VE278 as main screen

I normally just use my DS270, but tonight I decided to try a dual monitor setup
So I also connected my VE278 using HDMI and turned on computer, the DS270 only gave me a few streaks of a picture.
But was able to get a picture on my Asus (after turning off DS270)

I'm I missing some basic understanding of using dual monitors?

Would getting a SL DVI-D cable, connected from the graphics cards SL DVI-I port to the Asus DVI port work better?

I'm neither familiar with your video card, nor do I want to be.
What I know is that some video cards, when HDM is connected disable some video ports.
Your problem is kind of hard to solve because video card manufacturers are not very forthcoming with specs on which ports work together.
I'm sure you can find an answer by digging around on the interwebs.
For example, this card will handle 4 monitors: Zotac ZT-61102-10M GeForce GTX 650 Ti Video Card

Guess I'll get a single link DVI-D cable and see if that works.

Using a single Link DVI-D cable for the second monitor worked, nice having dual 27" monitors.
Now the problem is figuring out the settings for going back to one monitor.
