Using external monitor as a slave

by chrishe / May 24, 2006 11:04 PM PDT

I have a Toshiba Satellite 5200 Laptop running the latest verion of Windows XP.

This laptop has an external monitor port and I want use this second monitor as a display projector for presentations. In other words I want the external monitor to be an exact duplicate of the laptop screen.

Unfortunately the only way I've found to get this external monitor to work at all is by using it as display 2 on the Control Panel -> Display -> Settings tab. In this way I can set up two different windows to run in each display, which may be useful in some circumstances, but it's not what I want.

Isn't there a way of selecting this second monitor as a slave to the first? I've tried everything - I've even read the instruction manual! - to no avail.

Thanks for your help.

I think it's possible but I don't have the manual handy. From memory you need to disable TWINVIEW or change the setup to achieve your goal.

A call to Toshiba may get you a "do this" answer. Worth the call unless someone remembers the steps here.

Quite a few years ago, I was working not too far away, although my boss knew and trusted me, he was one of those people who liked to "have his finger on the pulse", in short, though he trusted me to run my section of the firm, he liked to follow what I was doing. To do this he got a second monitor and we connected it as I have mentioned.

The actual computer used was a laptop, though any computer would work. What happens is that the data cable from the video card is split, one part goes to a port on the rear, and the other to the built in monitor, thus giving the same picture. To do this with a desktop machine would be very much the same, except that the video card would probably have to have amplifiers built in, as with each doubling, the signal power to the data cable is cut by half.

So far as I know, this type of feature is only confined to laptops, I have never seen anything even remotely like it for desktop machines.

I have a powerpoint presentation and needed to show it on a projector. I enabled the second monitor and low and behold it worked. I got it going. Thanks a bunch.
