"Great experience and exactly what I was looking for. I would definitely shop with Sewell again."


minideck connection diagram

The Sewell Minideck USB to DVI/VGA display adapter is like an external video card you connect to your system, adding an extra monitor (supporting native resolutions of screens up to 24") to your desktop through a single USB port.

Once you have multiple monitors connected to your computer system, you will be able to use them in 'extended desktop mode' which means you can use all screens like one contiguous screen, or 'mirror mode' which shows the same image on both screens at all times.

Resolution Improvements From Past Models

The main improvement from past models is its new resolution capabilities. The Minideck can support up to 1920 x 1200 (native 24" resolution), 1920 x 1080 (1080p: Full HD for HDTVs), and 2048 x 1152.

How This Works

Installation is as easy as using the included CD to install the DisplayLink driver (or downloading the driver if you have a Mac), and connecting the USB and video cables.

Every Minideck comes with a DVI to VGA adapter so you can use a VGA monitor, and a DVI to HDMI adapter so you can go straight to your HDTV with beautiful 1080p. This is possible due to the Minideck's DVI-I (Analog and Digital integrated video) output. You will also need a separate audio cable to run from your computer to your TV's RCA audio inputs if you are planning on watching video with sound.

You can connect up to 6 Minidecks to your system to connect up to six displays to your computer. You can set screens to 'mirror mode' or 'extended desktop mode.'

Pros: I used the old Sewell USB to DVI (SW-8769) and needed to get another one (I gave the other one to a co-worker). This one is great - it's pretty similar except now it will drive my 24" monitor at 1920x1200 (native resolution).

Cons: None

Other: Keep up the great work!

MINIDECK Display Adapter

Pros: Easy to setup and install. Compact design/ size. Easy to adjust the resolution. Solid, uninterrupted performance!


Other: The Minideck is outstanding! I bought these Minidecks (8 of them) to test them against the Tritton SEE2 Xtreme UV200 which I had been using to support my array of 4 Dell 30 inch displays and my wife's 2 Dell 27 inch displays. I bought two extra Minidecks as "spares" thinking they probably would not perform significantly better than the UV200. I was wrong! My wife and I had been using the UV200 for several months and we had both experienced a growing number of "blue screen" system crashes with our Windows 7 OS and other distracting, time consuming problems. The simple act of rebooting our laptops to complete software updates was a ONE HOUR+ ordeal EVERY TIME! It took this long to reinstall the UV200 software in order to get all the displays to be recognized again. I was frustrated and increasingly dissatisfied... frankly I was sick of them and thinking about ditching the whole idea of using multiple displays! It was a bad experience, but I did not know how bad it really was until I set up these new Minidecks and was able to compare the poor performance of the UV200 with the stable performance of the Minideck. The Minideck software was simple to install, easy to use and it is perfectly, seamlessly integrated with the Windows 7 OS. The UV200 software was definitely NOT well integrated to the Windows 7 display controls... in fact it was not, by comparison to the Minideck, integrated at all! When my laptop went into Screen Saver mode, while using the UV200, my displays NEVER went into a power saving mode and the slide show would not run. With the Minideck, when the Screen Saver engages, all the displays go dark except for my main laptop display which runs the Screen Saver slide show, as it should. Our systems run 24/7 and now, with the Minideck, I have NO system failures AT ALL... NONE... no hiccups, no blips, no blinks... nothing to complain about. I am experiencing far superior performance and stability compared to the UV200. They actually perform perfectly.

My notebook has an intel 4 series chipset that doesn´t support rotating my desktop 90 degrees. I would like to use a 22inch monitor in portrait/tilted orientation. Can i use a minideck to help me out?


Yes, this should work well for you. The included driver application has a tool that will let you set the resolution and rotation easily from the taskbar,

Will this work with a Power PC mac mini 1.25mhz


Yes it will, as long as you are running OS X for your O.S. I was actually using 4 of these this morning on our Mac Mini and it worked great.
