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


This item has been discontinued, check out our new and improved Minideck 3.0 USB 3.0 to HDMI adapter (SW-30409).

Connect ANY Computer to Your HDTV

Connect your HDTV to your computer (Mac or PC) easily with The Sewell HDdeck. The HDdeck is an external video card you connect to virtually any computer through USB adding an additional screen (HDTV, projector or monitor). This will allow you to expand your computer's desktop space where you can watch videos, surf the web, play games, and more. It will not only handle video but also your computer's audio through the HDMI connection.

HDdeck USB to HDMI Connection Diagram

Once you have an additional HDTV or monitor connected to your computer system, you will be able to use them in 'extended desktop mode' (found on your computer's display settings) which means you can use all screens like one contiguous screen. 'Mirror mode' is also supported which shows the same image on both screens at all times.

How it Works

The HDdeck is a USB to HDMI display adapter. The secret to the USB conversion is the video compression algorithm inside this little external video card. It carries the top-of-the-line DisplayLink chip that guarantees smooth performance on your secondary displays just as if the display were connected to a true video port on your computer. That allows the USB pipeline (maxing out at around 480 mbps) to provide top-notch video connectivity including Hi-Def video and DirectX. This enables you to easily do just anything from photo editing to surfing the internet, watching movies, and play select games that support DirectX, such as Starcraft 2.

Installation is as easy as using the included CD to install the DisplayLink driver (downloading the latest driver is also avaiable from our site), and connecting the USB and video cables.

Integrated Audio

As an added convenience there is no need to run separate audio cables. This unit handles the audio and video soley through the USB port, making your set-up a lot cleaner and easier.

Up to 6 Screens at a Time

If you're looking for an inexpensive way to set up a video wall (with either extended desktop or mirroring) for 1080p high definition TVs, just use multiple HDdecks. Using six HDdeck USB to HDMI units and included software allows 6 simultaneous screens and allows you to arrange them in any way you want.

Pros: Great item. Does exactly what I needed it to do. Would highly recommend.

Cons: No cons as of now.

Other: With the HDMI cable and the USB Cable, I was able to go from the Computer to the TV with a good picture. The CD with instructions makes it an easy installation.

Pros: Works as described. You can change the resolution very easily, and it supports pretty much any resolution your TV/Monitor will support. Perfect HD output source. Audio was also fine.

Cons: It will take some time to figure out the best setup for your device. I had a difficult time finding a way to get video running smoothly. See other comments for my solutions.

Other: I don't see very much information helping people troubleshoot their problems. First off, follow the install directions. Install from the CD first, then turn your monitor/TV on and connect it to the HDdeck, and finally plug the HDdeck into your usb port. IF the image on the TV/monitor is too small or too big, this is probably a zoom/aspect ratio problem with your TV settings. Most TVs allow you to change the aspect ratio and screen fit through their own settings. Play around until you find the correct setting. My TV had a fit to screen setting. This corrected the display issues I was having. For good video playback I had to disable hardware acceleration on my browser. This was the only way I could get video playback to work properly. I'm not sure if this was just my problem, but if you're having problems this might help. For video playback from a media player, I've had to play around a lot. I do not have a solution for windows media player. What I do have working smoothly is VLC media player. The only way I was able to get smooth video playback was to change the video output. Go Tools->Preferences->Video and look for the output drop down menu. I'm currently using Windows GDI video output. So those are my solutions. Hopefully this helps someone out. If you don't use VLC already, get it, it's probably the best video player out there.

I had no idea how to connect this product, but a tech person on the phone spent almost an hour patiently walking me through the process. Works great now! Support is beyond excellent!

Simple to use, after installing the drivers on a Windows 7 OS, it was basically plug and play.
