Windows 7: How to Setup a Dual-Monitor?

How to Setup a Dual-Monitor?

I have one 15" Monitor which is here:
MAG HD 572 15 inch flat screen LCD monitor data sheet
I am planning to get a 24" 1920x1080p Monitor.

Instead of wasting my 15" Monitor, I would like to go Dual Boot with my current monitor:

I can see 4 Ports the monitor can go in (one is reserved already), so 3.

There are 2 Red ports: My Belkin Adapter goes in one and a blue wire goes to the adapter to the 15" monitor as it is a DVI Port, however it only works with the left one.

There is one Blue port - I tried this with the Blue VGA Cable it didn't work.

There is one white port - Labelled DVI and it didn't work with my adapter and VGA Cable.

I have provided some images.


The bottom image is two red ports showing the adapter plugged in and in the adapter is the blue cable

This is the monitor I have chosen to get:
BenQ G2420HDB Full HD TFT LCD 24" DVI-D Monitor | Ebuyer.com

I have an AMD Radeon HD 6770 Graphics Card

Can anyone tell me what I will need to do and if this will work and if it doesn't can anyone link me to a 24" monitor under 135 that will work.

Hi there,

You mentioned dual-boot. I don't think it's possible to run two os's at the same time unless you use virtualization.

In windows 7, there's a very good, simple interface which allows you to change all the basic monitor settings.
The monitor you want to buy comes with a VGA cable, so you can use that one besides your old monitor.

When you right-click your desktop and click "screen resolution", you can change the way of how your different monitors connected to your pc are working.

Hope this works!

Sorry. I was meant to say Dual View.

I still have no idea which the 2nd/1st monitor's port's go in which.

Use the DVI for your main 24 in and the VGA for the other. DVI is much better looking (digital). In the above mentioned control panel you can tell windows which is your primary monitor (the 24 I'm assuming) and then adjust the relative position of the second monitor (left or right or maybe even above? )

The only problem is before the 15" monitor won't connect to the VGA port. It displays No signal .

use the other red DVI port and plug in your new monitor to that and leave the old monitor plugged in where it's at.

The White DVI and Blue VGA ports are onboard video and they are most likely disabled since you have a video card installed.

Will that work? Considering the other red port that is not in use right now wouldn't work when I plugged it in?

The blue VGA and white DVI ports are for the onboard video on the motherboard, and can only be used with a video card (the red ports) if the bios allows it. In your case with only two monitors you can just use the video card. One of the two ports on your video card should support VGA via DVI-VGA adapter, one of these,

going to have to use the adapter seeing as your old 15" only has a VGA connection. Now with that said only one of the two DVI ports on the video card will support the adapter. If it doesn't say in whatever manual you got with the card or marked on it something like this,

then it is a simple matter of trial and error till you connect to the correct one. Then just connect the new 24" to the other.

It's possible that only one Red DVI port has the Analog VGA pins in it so that is why your Belkin Adapter only works on that one port.

Ah, ack heh. I saw your text about the red port but the second and third pictures didn't load when I was looking at your post before :/ Sorry.

Yeah what stormy said, You should have both monitors plugged into the same graphics card. You may have to "Extend my desktop to this monitor" on the screen resolution control panel to get a video out of both ports.
