Maxing out a machine with displays

I have three questions regarding the Plugable USB2-HDMI-165 USB to HDMI Video and Audio Adapter for PC to TV 720p and the Plugable UGA-2K-A USB to VGA/DVI/HDMI Adapter:
(1) How do these adapters utilize the existing video card(s) in the computer? We are already utilizing the existing video cards to capacity. (What we really want to do is how two video cards in the machine, each driving two monitors, and then buy 6 of your product for a total of 10 displays. Is this possible)?
(2) Have you tested this under Windows Server 2008 R2?
(3) Any chance you can compare/contrast your product with that of Diamond Multimedia?

Hi Dennis,

Thanks for asking ahead about USB Graphics and Windows Server 2008 R2. The maximum number of USB Graphics adapters Windows can utilize is 6. While it may be possible to run the DisplayLink drivers for USB Graphics with two internal graphics cards, it is not recommended (there is an opportunity for driver conflicts with multiple PCIe adapters). Therefore, the maximum number of monitors is 8, 6 USB and two from a dual output Graphics card.

As far as how USB Graphics utilize the graphics cards in the system; the drivers do require an internal graphics card in order to function however the graphics rendering is accomplished on the main CPU.

Windows Server 2008 (R2 has received limited testing) is certified to work with the DIsplayLink drivers as per the release notes available here:


In comparing products, both the Diamond BVU195 and our Plugable UGA-2K-A ( use the DisplayLink DL-195 chip. That determines most of the basic characteristics (including sharing common drivers from DisplayLink), so they’re very similar. We include a DVI to HDMI adapter in our product, where the BVU195 doesn’t.

You’ll tend to get more updated firmware and drivers from us (we refresh and improve the product often). We also aim to provide different & better online customer support through public problem reporting and resolution (making it easy to search and find information about our products). We make sure our customers are happy, with tech support, replacements or refunds as appropriate.

I hope this helps in making your decision.
Let me know if there’s anything else I can do to help,

Thanks for this reply. It is very helpful. Just another quick question, since this was replied 7 months ago (as of August 2012), is there a newer product (with more powerful chipset than the DisplayLink DL-195) as of right now? If so where can I find it? Thanks!

Hi whchuang,

There is a USB 3.0 line out now. You can see the full selection here:
