Dual Monitors not so dual

ellsy82 · 07 Jan 2013

Greetings all.

I'm having a slight problem figuring this one out. I shouldn't, but this problem is kicking my rear. I've got two AOC monitors set up for a client, yet they don't actually portray a "stretched desktop" over the two monitors. It Displays one "widescreen image of my desktop on the right monitor, and what looks like a fullscreen image on the left. I've gone through the usual setup for dual monitors...

Change Display Settings ->
Select 2 in the monitor selection screen ->
Select "Extend" in the other option menu.

I've tried "Windows + P" and tried it that way too.

I've made sure they're the same resolution and an display hertz are the same. I hope to the Gods that this is an easy fix and one of you will have a quick solution for me, but I've gone over all my specs and I just can NOT figure it out. Its usually an easy setup, but for some reason, I'm stumped.

Are they the same model AOC monitors? How are you connecting the monitors...what type of cables? Are you connecting them both to the mobo or to a gpu or one to each?

Haha. Yeah, they're on a VGA splitter. Same model number on both monitors. Could that be a problem?

I wouldn't think so. I mean, the computer recognizes both screens. I just can't figure out why it won't 'extend' the two. Infuriating.

Unless the port on the card is dual head, that is the problem. They need to be connected to separate ports on the card.

Additional info: The monitors are imaging eachother, like it recognizes the second monitor, but just replicates what you see on the first one.

Again, the left monitor is in "full screen" format, like it cuts of 20% of the screen on either side. The right one is "widescreen", as it should be.

So both of them need to be connected to the actual computer? I've seen this same splitter work hundreds of times.

Well, technically I've never tried it on a stand alone video card. Hmmm...Let me give that a shot.

Update: Impossible. There's a card lid that overlaps the lip of the video card slot. So much so that I cannot even insert a VGA connection into it. I've got a VGA-2-DVI connection working currently. *sigh*

As far as I understand a VGA Y connector will only mirror the first monitor to the other.
The best way to use the extend desktop the way you want it (desktop to take up both monitors completely) you would have to use the video cards software, such as AMD's eyefinity to do what you are looking for.
