Diamond Multimedia Launches DV100 USB3.0/2.0 Dual Head Display Adapterby Ryan Smith on October 16, 2012 4:30 AM EST

In recent years Diamond Multimedia has been carving out their niche in the world with an increasingly vast array of video periphials, including video capture devices, Android based media streamers, and of course video cards. This includes both traditional video cards and external display adapters based on DisplayLink’s video-over-USB technology.
So far those external adapters have been based around USB 2.0 – which has a rather anemic peak bandwidth of 480Mb/sec – but with the introduction of USB 3.0 and more recently widespread USB 3.0 deployment in Intel’s Ivy Bridge platform, Diamond’s external adapters are finally getting a boost in capabilities thanks to USB 3.0's order of magnitude increase in bandwidth. Joining Diamond’s existing USB 2.0 based adapters will be their first USB 3.0 based adapter, the DV100, a dual head display adapter.
As hinted at by the product name, the DV100’s main selling point is that it’s a dual head display adapter, the first such adapter from Diamond. Diamond is primarily pitching this to laptop users where expandability is extremely limited, and at a time where even DisplayPort laptops are still limited to 1 monitor per port due to the lack of MST hubs. To that end the DV100 sports 1 SL-DVI output and 1 HDMI output, each with a maximum resolution of 2048x1152. The DV100 offers both mirroring and extended desktop modes, with the HDMI port also supporting 5.1 channel HDMI audio. The DV100 is completely USB powered so power consumption is quite low at under 2.5W, though like other USB based external adapters this goes hand-in-hand with its limited performance intended for desktop work and video streaming.
On the technical side of things, like Diamond’s other external adapters the DV100 is based on a DisplayLink chipset, with Diamond tapping DisplayLink’s DL-3900 for this product, DisplayLink’s top-tier USB 3.0 chipset. While it’s primarily meant for use with USB 3.0 the DL-3900/DV100 also offers USB 2.0 fallback support, though it’s not clear what the impact is on the DV100 given the amount of bandwidth that’s needed to drive two displays. Meanwhile it’s interesting to note that though Diamond is primarily using the DL-3900 for its unique dual head capabilities, the chipset supports several other features that Diamond doesn’t end up using, including Gigabit Ethernet and DisplayPort support.
Finally, with this launch Diamond is explicitly noting that the DV100 will be augmenting Diamond’s existing external adapter lineup (BVU195) rather than replacing it. The DV100 will be launching at a MSRP of $79.99, $10 over the existing BVU195’s MSRP of $69.99. Though if retail prices on the DV100 are anything like the BVU195’s, then it shouldn’t be uncommon to see the DV100 $10 below MSRP.

MGSsancho - Tuesday, October 16, 2012 - linkLimited application use as there is little hardware acceleration. Depending on the application this may not be an issue such as presentations with little video. However systems with USB3 should be fast enough to drive most applications over this device.
Telek - Tuesday, October 1, 2013 - linkI've used the USB2.0 older version with full screen HD video, works fine.
MrCromulent - Tuesday, October 16, 2012 - linkThe spec sheet lists Mac OS X as supported operating system, although the generic Displaylink USB 3.0 drivers don't support Mac OS yet. Has this changed or did Diamond write a custom driver?
DanNeely - Tuesday, October 16, 2012 - linkI'd be really interested in seeing this tested to make sure it actually works well. USB3 has enough theoretical bandwidth to run a display well; but will it be low enough latency to keep the UI smooth.
Shadowmaster625 - Tuesday, October 16, 2012 - linkWhy not throw in an ethernet port and a few usb ports for peripherals? Then just call it a dock?
jibz - Tuesday, October 16, 2012 - link2048x1152? Why not 1920x1200?
DanNeely - Tuesday, October 16, 2012 - linkIt's probably both. 2048 is more pixels and thus is nominally the higher resolution. It never caught on anywhere but several years ago several companies did sell 2048x1152 monitors.
knowom - Wednesday, October 17, 2012 - linkI blame price fixing and then being phased out for the reason it never had a real chance to catch on. If they offer monitors now with that resolution for $150-$175's I would probably all ready own one by now.
stankpuff - Tuesday, October 16, 2012 - linkI've been running the GWC-branded version of this for several months now. It looks exactly the same as the Diamond one shown above sans the Diamond branding. For those that are wondering, it works great. Any UI on the GWC is smooth, Aero is enabled, and it can even play video. The only problem is that you've got to be a little careful with DisplayLink's drivers. Their summer driver release completely borked the setup (jerky UI, forced Aero off). However, I reverted to an earlier build and everything works fine again.
