Matrox Graphics eXpansion Module DualHead2Go Analog video converter D2G-A2D-IF

Pros: Simple to install hardware and easy loading of software drivers

Cons: Can't use 2 monitors with different resolution. Well, you can, but you'll have to opt for the lower resolution monitor. As someone else had stated, this is not a true dual monitor solution, this just splits the video port into two so you can connect the two monitor. Support was lacking. I have a current dual monitor setup and was switching to a laptop. One monitor is 1680x1050 and the one is 1280 x1024.

Pros: I’m driving dual 1600x1200@60Hz panels with no problem with my notebook. Installation was easy and it worked the first time. Neat product.

Cons: I did have a slight ghosting problem when driving the Dualhead2Go through a docking station. Direct connected to the notebook works great.

Pros: Does what it claims; used w/older video cards on Linux and 2010-11 era Macbook Air w/the VGA adapter It succeeds in fooling the computer into thinking I have 1 large monitor w/no problems Sure beats messing with multiple video cards

Cons: none really DVI input might be nice but adapters work could be higher resolution (1920x1440 is what my 4 year old 24") monitors can do; this only goes 1920x1200 and less off a Macbook Air which I dont use very much anyway

Overall Review: Plan to use with a 6 year old ATI Radeon dual headed video card and 3 24" Samsung monitors to get 2 x 1920x1200 (via DVItoVGA adapter then into DualHead2Go into the older Samsungs) and 1 x 1920 x 1080 (out the 2nd Radeon DVI port into a brand new 24" Samsung) It took Linux (PCLOS) KDE System Hardware Settings to get all this setup and working together (no hand edits to xorg.conf for once)

Pros: Meets all of my expectations and works as advertised for the most part.

Cons: I had to mess around with the settings quite a bit to get it displaying at full resolution on both monitors. I'm not sure exactly what fixed the issue, but eventually it started working. Window maximizing behavior doesn't seem consistent with all programs, and does not always conform to the settings.

Overall Review: After purchasing and looking for a solution to my resolution issue, I came across the System Compatibility Tool, which you might want to check before you try installing this device on your system. http://www.matrox.com/graphics/en/support/drivers/download/gxm/tool/

Pros: Enables me to use lots more desktop for my programs. Seems like a solid built little box. Uses the usb for power now. (unlike previous models that had a seperate power supply.

Cons: I had some initial trouble getting the max resoultion until I upgraded the firmware. Now is great. The other thing I can't figure out is why I have some smearing or ghoasting of the graphics on the outputs??? I still haven't resolved that one.

Pros: Does exactly what I need. Needed two external widescreen monitors. This allows for much customization. Other reviewer was incorrect - using the software provided, you can choose where applications open. Indeed, treats 2 monitors as 1 uber-wide screen (cool for wallpapers) but also recognizes it as two displays. You can choose display 1 or 2 for apps to open. I am even able to make my rocket dock go to a single display. I am software engineer and this hardware makes my job easier. Would purchase again.

Cons: Not really a con.. but this is complex piece of hardware and will take some software configuration to give you exactly what you want in terms of screen placement etc. Good news - I have had this roughly 1 month and have been able to configure exactly as I want it - many options.

Overall Review: I would recommend this to anyone wanting to use 2 external displays with a laptop that has 1 video out.

Pros: can use 2 screens

Cons: Doesn't work

Overall Review: Bought one few months ago and it worked for about a month. Then I installed DisplayFusion and it was constantly conflicting with that. Maximizing various applications like YouTube was outright broken (it would stretch over 2 screens). Then it just stopped working completely. No power light, nothing... tried everything, plugging into different ports, re installing drivers, making sure my usb is powered, trying different computer, etc. Couldn't find any solutions online or manual, guess I just threw away $200. I don't recommend buying this product.

Pros: Combines (2) 1080p monitors into a single,virtual 3840x1080 monitor Lets laptop utilize (3) monitors with a single VGA output (laptop screen + 2 externals) Functionally, it's perfect. I have it strapped to my dual-monitor stand, with the cables all neatly wrapped. Used the HD15 VGA cable that came with the monitor to bring the cable to the laptop. USB is connected to a hub, so the ONLY reason to connect USB to the laptop is to take advantage of features in Matrox Powerdesk (maximize to the monitor where the application resides, etc.) Alternately, you could power this off of a spare USB wall-wart, assuming that you didn't want the Powerdesk functionality.

Cons: Setup can be tricky ... the new GUI for Matrox Powerdesk is inferior to the old version that I had for a TripleHead2Go digital. It's prettier and has a few more options, but it seems to be more difficult to use. If the VGA cable is disconnected without power cycling the laptop, when it is reconnected, the Matrox unit connects to the monitors with an unsupported timing/resolution scheme. Words of advice - save your favorite configuration to a keyboard acclerator (mine is CTRL+ALT+SHIFT+0). Makes recovering from the above situation easy as pie.
