More Screen Space

We live in the age of multi-tasking. Both at work and at home we need all of the screen real estate we can get. The problem is, our devices, and therefore our screens are getting smaller and smaller. Additionally, you can’t add video ports to most devices these days (pretty much anything except for those old fashioned, tower style PCs), that can cause you problems if you want to have two or more monitors. That’s what makes the Minideck 3.0 so great, you can easily add up to 6 monitors (up to 4 on Mac) via USB. And with the new chipset and USB 3.0 in our newest Minideck, you are assured the best USB graphics performance. Learn more about the benefits of multiple monitors.

New Chipset

Slow transfer rates can cause you to have choppy streaming and lag when watching video. By upgrading the chipset we have greatly increased the speed and power of the Minideck 3.0 by adding real-time adaptive compression technology. In order for your computer, the Minideck, and your monitor to transfer data, the data needs to be compressed. This process of compressing and decompressing data can affect your transfer rates. Real-time adaptive compression balances compression methods from moment to moment based on content, USB bandwidth, and CPU power availability. That means that you have the best possible USB graphics experience at all times.

USB 3.0

SuperSpeed USB 3.0 is capable of achieving transfer rates of up to 5 Gbps. That’s ten times faster than USB 2.0. USB 3.0 is also bidirectional, which allows your external devices to send and receive data simultaneously. All of that translates into fast, reliable video that you can display on multiple screens without lag.

Note: If you don’t have USB 3.0 ports, the Minideck 3.0 will still work and the updated chipset means it will still be faster than older Minidecks. However, to take full advantage of the Minideck 3.0s capabilities, you’ll need USB 3.0 ports on your device.
