I have a Dell Win7 laptop that is already running two displays - the integral monitor and an external monitor on DisplayPort. My video card supports only two monitors, total. (I can alternatively run the external monitor on VGA or HDMI, but I cannot...

I'm not sure if this wil be a helpful answer, but here goes ... The HP monitor gets it's signal and power through the USB port, and it required that I install a special driver. It doesn't use a video card, external or otherwise. I use this USB monitor attached to my laptop, to which I also attach an external VGA monitor. So I get three screens but not in the way you want to do it. I have had absolutely no trouble with the USB monitor at all. I would suggest giving it a try. Order it and see if it works, and return it if it doesn't.

I have 2 monitors connected. One connected to the DVI port and the other connected to the display port using the adapter that came with the card.

There is a VGA, HDNI and DVI port on the back graphics card. We are only driving a 26' monitor, so I don't know if it drive multiple monitors.

yes, I can confirm as well. One DVI port, one VGA port. I am using both in a triple monitor setup (with one being the laptop screen).

You can use the DVI and HDMI to run two monitors. You can also use the DVI connector and the onboard VGA connector. That is the way I use it (my monitors don't have an HDMI connection). To use the DVI+VGA you have to go into the BIOS setup and enable the onboard VGA.

I believe the answer is indeed no. Don't have the technical terms at my fingertips, however I've been running lots of monitors with various graphics cards for years. In the end it seems to always comes down to the number of GPU's when running HDMI, DVI, or even older VGA monitors. I believe there is a technical limitation that you can only run 2 HDMI/DVI/VGA monitors per GPU. Since this only has 1 GPU, you can only run 2 non-DP monitors. You could however, run 2 HDMI and then more DP monitors at the same time. For me I just used all DP monitors and it has been working great for business apps etc. I believe the answer is indeed no.

Your video card may not be compatible with three displays. Check the manual of the video card for more information. Also, your monitor has to be able to communicate with the video card. Some older monitors are not capable of this.

Agreed! We like out Dell as well! We use ours very portable and have not tried hooking it up to an external monitor. However, have you tried going to "Control Panel\Appearance and Personalization\Display\Screen Resolution" and adjusted the resolution settings? I've often used this at work to use various laptops with various viewing hardware in conference rooms including old 36" tube TV's and have generally found a resolution that works from the controls of the laptop operating system. Windows 7 has 15 different resolution settings. Older version do not have that many if I remember correctly. Anyway, good luck and I hope you find a solution. Agreed! We like out Dell as well!

This card only supports two monitors. Assuming you are running a recent Intel CPU you should be able to run an additional two monitors off the integrated CPU.

I am running Windows 7 and the docking station does support 2 external (1 - VGA and 1- DVI) external monitors on top of your laptop monitor. All in all, you can have three monitors active at any given time.

The Windows7 OS's support dual monitors...there is a Video Adaptor plug AND a HDMI plug...but I'm not sure you can use both at the same time....query ZOTAC about that one.

That is exactly how I'm using it. The HDMI is plugged into my Dell laptop, and it is connected to a VGA older monitor so I can have a second screen. It works like a charm!

I don't know. The graphics card I have will drive a second monitor. each touch screen has a usb 3.0 connector needed for touch screen operations. Maybe adding a second graphics card would enable 3 or 4 touch screens.Check with Dell customer service. Sorry I cant be of more help. Good luck,Paul Evers

I'm running dual screens. It depends upon your video card I believe and not the monitors if you have two video outputs etc.

I'm having the same problem. Acer says that if you add an adapter card, the onboard adapter is disabled. This is ridiculous. I have since bought a dual monitor invidia card and it won't show two monitors either. The Acer must be blocking it somehow. To boot, Acer's support sucks, It's going back where I bought it, right now.

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.

first of all john, nice name. onto the question though, i personally have been unsuccessful at using a triple screen display with a single videocard, BUT thats not to say that its impossible, i have tried an active adapter that goes from dvi (dual link) to vga, however it might work with the displayport, but i do not have the money anymore to try it
