Does this device extend or mirror the displays? i.e if I plug it from my pc to 2 monitors, would the monitors display the same thing or different things?

I set the system up through the Direct TV sat. So for me to change channels both displays would mirror. My understanding is that would be the rule.

It will extend your desktop too. It has some glitches like blacking out during high volume processing such as using ArcGIS tools. But for the price, it gets the job done. Next time I think I'll try a higher price product. The resolution with the VicTsing is actually better than plugging the second monitor into the Panasonic Toughbook's VGA connector!

You are correct, this box only boosts and splits the identical output to 2 monitors. If you want to EXTEND your desktop to a second or third monitor, and your equipment doesn't already have a dual monitor video card (or if it is a laptop), then you need a device like the Plugable (brand) devices found on Amazon, which are USB to VGA/DVI/HDMI Adapters. There are at least 3 different models, one for USB 2.0 and one for USB 3.0, at various max resolutions and prices. Hope this helps!

I use the Hdmi and the Dvi to run 2 screens. Can be mirrored or extended views on the monitors.

I am assuming you want to "extend the displays"? If this is so then no, your video card needs to have two monitor ports in order to "extend the displays". You will only be able to mirror them with this splitter.

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.

No. This will mirror your screen not expand it. If you want to add another screen you will need either thunderbolt or a usb graphics adapter.

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

It will give you the ability to have 2 monitors plugged in as an extended desktop. I run it on my MacBook air and have 2 external monitors set up. It shows a display resolution of 3840 x 1080 now and works great

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

You will need to go into your display settings and choose the extend option. It is a little different depending on the Operating system you have. I have posted the most common below.

Not with this device. Also, supposedly this device can also switch back and forth between two monitors from one computer. It doesn't do that either. In fact the one I bought did nothing at all and I threw it away.

Yes it does. I actually hadn't tried yet, but I hooked in a third monitor and it detected it and gave the option to extend to the third montor.

Thanks ioioi210. That's pretty lame that they advertise support for dual monitors then. While technically you can have two monitors lit up, I don't think most people are looking for mirrored displays.

It will extend, but the extended desktop will be duplicated (or quadruplicated in this case) in all four monitors. This doesn't create 4 screens that sequentially extend your desktop.

I am sorry to tell you that I made the same mistake. All you can do is mirror the DVI input. One thing I am working on though is creating aa custom driver that will double the virtual width of the monitor resolution while still maintaining the same height. I have gotten close once but the aspect ratio for the width doubled as well. Resulting in watching movies with a bunch of short fat people. My work around for now is to use the vga jack out of my laptop for one 23" monitor and an HDMI to DVI-D adapter and DVI-D cable to my other 23" monitor. This gives me 3 hi-res displays to use. Not the most elegant solution but it works. If you find an answer I would love to here it. If I get my custom double wide driver to work I will be happy to share. Cheers, CJ. Cjchumbley@computer.org

Yes, one to VGA & the other to HDMI. You may need an adapter. You can extend or mirror the two displays. See - Control Panel\All Control Panel Items\Display\Screen Resolution. Had no issues.
