does this just duplicate the display or would it let my computer have multiple monitors

duplicated the same signal, so computer could have multiple monitors but all same picture

I'm using it on a tv and it duplicates the output and give you four of the same outputs.

It works with a VGA external port (using the hardware functionality) and also if you have a more modern laptop it works even better with the Micro-HDMI and Windows configured to duplicate monitors.

This only allows one additional monitor to be plugged in. In addition to a currently running monitor. This will not allow you to run 2 monitors plus your standard monitor. It will only allow a +1 monitor

Yes, you could easily do that. You would tell monitor 1 and 2 to use "extended desktop" then tell 3 to duplicate 1 and tell 4 to duplicate 2. I just checked the settings on the one I'm using right now and it works just like you say. You would just need longer cables to reach the other location.

Go to your control panel and look under display. If your laptop shows the option of extending your screen over multiple monitors then your laptop HAS the capability of doing so. Most laptops provide this option. However, as I've never used this device I cannot say for certain that it would work this way. I did want to correct some of the previous incorrect answers however in terms of capability.

I have it setup so that either of my laptops can use one central monitor. First you need to figure out what you want your central monitor to be, plug that central source into the VGA out, then the two devices you want to use this display would be plugged into the two in ports.

As far as I know, this splitter should allow two screens to show duplicates of what is showing on your laptop. This isn't what I used it for and I haven't tried it.

Not sure what display monitor extensions are, however I guess that it is something to enable viewing 4 different signals on 4 different displays. This is a Distribution Amplifier. It will take one signal in, and display that same signal on up to 4 displays. If you want to see 4 different signals on 4 different displays, you'll likely have to use 4 different computers, or perhaps 4 different video cards in one computer - with the appropriate software.

I'm not sure because I only use 3 monitors. There IS a selection to duplicate the display on monitors 1 AND 2, OR on monitors 1 AND 3. I don't know if you'd have the selection you want if 4 monitors were connected. I'd suggest that you email the manufacturer directly at support@visiontek.com and ask your question. Their website is at http://www.visiontek.com.

The splitter will only mirror the display. To get a second monitor independent of the first your video card needs to have 2 outputs, OR, you get a second video card. Newer computers with display-port or thunderbolt (Mac) can daisy chain monitors. Since you got a dvi splitter I'm guessing your computer does not have thunderbolt or display port. Best option is a second video card, or replace the current with a 2 or 4 port video card.

the device has two display ports , one hdmi, one dvi and one vga port, if your monitors has support display port display is ultimate otherwise you will have 2 different quality display, my monitor support display ports so no problem for me

This depends on your graphics cards. Most can be cloned or extended to one other monitor.

Yes and yes. It will basically take one VGA signal (15 pin) from a computer and split it to 4 monitors or projectors. All monitors or projectors will show the exact same image.

No, it will not. It will only allow you to see the same image on two monitors. It is only electrically copying the output.

Duplicate screen worked from the box for me. Plug in, go to display, select which output.

There is also a DVI output but I have not used multiple displays. However if I had to bet my life on it I would bet that if there are multiple outputs you would be able to use 2 monitors.

It depends on your video card, this is not related to monitor, I believe most of video cards have the option to hook up more than one monitor. the monitor is great, I use it for 2d, used it for 3d gaming once or twice.
