How to make two standalone monitors a dual-screen?

Oct 17, 2014 12:47PM PDT

Hello. Want to buy a dual screen. They are too pricey. So want to buy two cheap single monitors and connect them. But there is only one jack on the computer for the DVI plug. So, what do I do? Do I buy a DVI splitter, hook the single end to the computer, and each end of the forked end to the respective monitors? Or is there some other trick? Thanks.

A cable would only duplicate the display.

One monitor or two?

Hello. Thanks for responding again. I don't understand. Are you saying to get one USB monitor that you can split into digitally.

Yes, I would love the ease of a USB monitor. However, I need split screens. Are you saying to get this one monitor and digitially split or to get two of these and plug them into separate USB ports? Thanks.

Also, you said a cable would just duplicate the display. But my understanding is that you can go to control panel >> appearance and personalization >> display >> screen resolution in Windows 7 and take them dual monitors.

But, yes, I am interested in your USB idea if I could understand it. Thanks.

But the problem is

that the same cable feed to each monitor would simply send the same display data to each monitor. To see dual screens you need separate feeds to each monitor.

I have never seen a USB Display myself, but trust me, if Bob says it works as a dual monitor, then it does.

In fact, looking at the Amazon link Bob provided, if you roll over the 6 images of the display on offer, you will see one where it shows different displays on the two screens. It will work with either a laptop or desktop PC

As you say, you set dual monitors up through control panel >> appearance and personalization >> display >> screen resolution in Windows 7

You still need two monitors

Hello. I read the information for the USB monitor. It says that you have to plug in two monitors. See here:

Built-in DisplayLink Technology for Multiple USB Monitor Connections

If necessary, multiple USB monitors can be simultaneously connected to a laptop to function as a multi-monitor PC, thanks to the built-in DisplayLink USB graphics. Simply installing DisplayLink software on the PC allows you to easily add multiple USB monitors for external displays without unnecessary extra hardware. The e1649Fwu USB Monitor gives you multiple external displays for your laptop without any complications.

That seems easier than getting some kind of adapter, and I may do it for convenience. However, I could probably get no-USB monitors cheaper. That's why I want to know how to make them dual monitors. Please help. Thanks.

Get one or two?

Are you saying to get two of these, one for each monitor?

The USB monitor idea was great but (1) the monitors had no stand and (2) you can't control the brightness or anything. I like to control the brightness/contrast/etc.

Thanks.

Sorry

It appears that you need some one on one support. That is, it's well known that you can't use only USB displays on Windows. OK, you could get 2 displays and some USB video card. But as I look up that was tossed up as an option.

Something's not right here. What's going on?

Clarification
Oct 21, 2014 7:07PM PDT

Are you saying?:

1. Hook up one monitor normally.

2. Hook up another monitor w/ a USB extension.

Thanks.
