I need to expand my laptop screen to 3 monitors. Does this device work like Matrox Triplehead2Go?

As long as you have the available USB ports, you can add several of these. I have used the VGA/HDMI out ports, along with the USB to power 3 monitors with no problem. (Note, that this is with the Laptop's monitor, one monitor output port, and one USB adapter port). Where the Triplehead2Go will take one output port and make it 3, this USB adapter will only supply one monitor per unit. So to get a total of 3 monitors, you would have to have to use one of these per USB port. I hope this answered your question.

I don't know what the Matrox Triplehead2Go is but as long as you have 2 USB2.0 ports on your laptop and your Graphics controller can support up to 3 screens this works like a charm. I have 3 monitors on my pc one driven from the USB port and 2 from the graphics card directly. I have a friend running 4 monitors and using 3 of these things. The work great as long as you aren't expecting high speed / high performance graphics off of them.

No it does not work for different monitors, you need a video card for the extended monitor to work.

This cable will only duplicate 2 monitors. You will have your main screen example if you are using this on a laptop. Then you will have your laptop screen and you will have a extra screen on two monitors. Both of these monitors will display the same thing. If you want 3 separate monitors you will need another video card. I know they have a few Usb video card options

Yes, I just tried as you described using my Dell Latitude E5530 and was able to extend desktop onto two monitors (one via adapter, other connected to VGA port) while utilizing the laptop display.

NO, it by itself will support two monitors. you would need a second video card to support a 3rd and potentially 4 monitor.I needed to get this video card, to go along with another video card that i had to support 3 monitors.But this card (GeForce GT 610 has been a great video card for me...no problems with it.

The card has three possible outputs to monitors, but I have never seen software that will drive three monitors. I use UltraMon and it is limited to a dual monitor setup. My guess is that you'll be limited by your choice of software/drivers.

Not concurrently, in my experience. It will let you toggle between 2, if you have 3 connected. If you want to have a third monitor for basic 2-D stuff, you might get one of those add on USB-DVI/VGA devices, but they are CPU intensive.

I use it to extend the desktop from my laptop to another monitor and it works just fine. I don't have personal experience beyond that. If you are extending to more monitors than the main and one more, you may be able to use two adaptors; just a guess.

Should work with the third monitor. You need one of these devices per USB slot per monitor.

Most likey not, most computers will prioritise one output over another or have you select what output you want it in. And if the computer doesnt have you select it your tv will. For example "hdmi 1" or hdmi 2." id advise searching "how to set up a 3 output display with laptop" on youtube.

It will extend the screen just like any dual-monitor capable video card would. I tried it on mine just to double check!

no it will not work, you will need to purchase an **active** display-port adapter in order to do 3 monitors. Atleast one of your 3 monitors will need to be set up with an active port and the other two can be hooked up with any other type of connection.

Most laptops can handle up to 3 monitors with the help of an external USB video dock...I have a Sony VAIO and i am using 3 monitors with the aid of an external dock. If your question is to achieve this with just your laptop, then I am not sure the video card can handle multiple laptops just by itself.

We use 2 Monitors with it. One plugged into the HDMI the other via RGB extending or duplicating the desktops works as it should. All scenarios have worked so far so we have 3 screens essentially and it works a treat. Ours came with no software. We have installed 8.1 and Office 2010 and all works as it should.

The additional monitors connected with this splitter will show exactly what you see on the computer's monitor. In order to extend the computer's desktop I believe you need to add another video card, and I don't think this is possible with a laptop unless the laptop has an expansion slot for "Express Card" expansion cards--you would need to buy an Express video card and put it in this slot and connect a second monitor to this card. Good luck.

I have an HP laptop and this device gave me three monitor capabilities. I can use the laptop's screen as well as a monitor connected to the laptop's VGA port and another monitor connected to this USB device's VGA port. So counting the laptop's monitor, I have three screens available when using this device. All I had to do was load the software that came with this device and then connect it to a USB. While setting up the dual monitors, which is all that I had expected to be able to use, I found out I could also use my laptop's screen. I have a docking station for my HP at home and the software only sees two external monitors. I don't use a docking station in the office and I can use all three screens.

The device, standing alone, will not allow you to run two monitors. It has one HDMI input and the output is through the thunderbolt cable. However, by doing this, it frees up the video port on your computer. I have two external monitors running from my laptop. You can also get a video usb adapter and hook it up to the matrox and run 3 external monitors. However, as stated before, the Matrox by itself only supports 1 monitor.
