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.'

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.
