Dual monitor with laptop?

by kai198 / July 9, 2013 11:39 AM PDT

I have a laptop and i keep the lid closed (the screen broke) and i use an external mouse, keyboard, and monitor. Recently, I bought a second external monitor and a vga splitter ( http://tinyurl.com/l7bggmj )
I plugged it into my laptop (again the lid of the laptop is closed) and the computer registers it as one monitor and duplicates whats on the screen.

Can anyone help me out? I'm trying to extend those two screens.

Splitter? That would give same image on 2 displays.
by R. Proffitt Forum moderator / July 9, 2013 11:43 AM PDT

Very few laptops support 3 displays. That is the internal and 2 externals.

To get more screens the most common method is an USB Video card.

When i go display settings, only one monitor is shown
(because the lid is closed and the two external monitors are being viewed as one.

Which is expected.

But while I disagree with "two externals viewed as one" it won't change a thing. Too bad you didn't supply the make and model so I could check if it supports 3 displays. Few do.

I agree with Robert, all you've done is made two displays(duplicate displays) of same screen which is what a splitter does. The same signals drives both displays. Unless the splitter has some feature to do otherwise, this all you're going to get. This is NOT the same as a video card with multiple ports, then you can tell the system using the video card s/w to drive two displays and select either as a "one wide screen(combined)" or dual but different displays; 1 & 2. Your splitter only makes two displays like in 1 &1 setup.

Basic splitter
by Willy / July 11, 2013 1:32 AM PDT

You've shown the basic splitter, it will nothing but provide a signal(same) to both monitors thus same display. It offers nothing else. A setup like this would be used a training or teaching device to offer displays across some location or wall, maybe a kiosk. Once, you get into more expensive splitter then some features or options maybe build-in or accessed by s/w.
