Plugable Launches the HDMI to VGA Adapter Cable

The new Plugable Passive HDMI to VGA adapter cable is a fantastic new product that does, quite literally, one thing. It allows you to connect your HDMI outputting devices to a VGA input like a monitor or projector.


The HDMI to VGA adapter cable is truly a great advance. As chips have gotten smaller we’ve been able to cram the chipsets found in giant converter boxes and bulky adapters into the nice form factor of a simple cable. The chipset is so small, you might mistake this cable for just another run-of-the-mill cable, but this so much more! With the built-in CH7101 chipset, this adapter will let you breath new life into your old displays.

The HDMI to VGA adapter cable is the time-traveler of video cables, allowing you to bridge your fancy futuristic computer with HDMI outputs to your aged monitors and legacy projectors with VGA inputs.

Plugable Launches Dual Display USB 3.0 to HDMI/DVI and Ethernet Adapter for Windows (USB3-3900DHE)

With just a couple of display cables and an Ethernet cable, Plugable’s new USB3-3900DHE lets you turn your Windows tablet or laptop into a traveling productivity powerhouse.

Featuring a minimalist design that maximizes the functionality of the DisplayLink DL-3900 chip, the USB3-3900DHE is a perfect companion for any business traveler with a Windows laptop or tablet. It turns a Windows 8.1 tablet without Ethernet and video ports into a mobile multi-monitor machine. Or combine with a powered USB 3.0 hub to build a customized single-cable USB 3.0 docking solution.

Its dual-video outputs (HDMI plus DVI with a DVI to VGA adapter) and a gigabit Ethernet port are connected back to your Windows PC and powered with a single USB 3.0 cable. The DVI and HDMI outputs are completely independent — able to drive two additional monitors of any resolution up to 2048×1152 with arbitrary positioning and an extended Windows desktop across them both. The USB3-3900HE packs the single-cable docking experience you enjoy at your desk, into a compact package to take on the road and into the conference room.

DisplayLink’s drivers have been updated to take full advantage of Windows 8.1 on this adapter. New features in Windows 8.1 provide users a more traditional Windows experience, while making the most of the Modern UI Metro applications introduced in Windows 8. You can boot straight to the desktop and display your Metro applications on one screen and your desktop on another. You can even mix and match your Metro application configurations.

Improvements to the Windows taskbar and enhanced Start screen options drastically improve the Windows 8.1 experience on multiple-monitor systems. Simply adding your desktop background to the Start screen can go a long way towards alleviating the disjointed experience of Windows 8. The ability to automatically show apps on the Start screen and prioritize desktop apps can provide a much more familiar experience to users who prefer the traditional Windows Start menu.

USB graphics is “virtual” in that it uses the CPU and GPU to do all rendering. So it’s not recommended for 3D gaming or full-length movies (youtube quality is fine), and it requires a PC with 2 cores 2Ghz or better for low-latency use.

Mac users — be warned that OS X support for display over USB is currently very limited, especially for dual-head products like the USB3-3900DHE. The DisplayLink drivers are beta-grade for 10.8.5 (Mountain Lion) and alpha-grade for 10.9 (Mavericks). Due to multiple issues and limitations with dual-head displays, OS X 10.9 should be considered to support single-head display only, until DisplayLink and Apple are able to put out point releases on 10.9 in coming months.

Upgrade to OS X 10.9 (Mavericks) Will Likely Break Existing Multi-Monitor Setups that Use Plugable USB Display Adapters and Docking Stations

Testing by Plugable of Mac OS X 10.9 (Mavericks) has exposed changes that will break multi-monitor setups that use Plugable USB display adapters or docking stations for more than one monitor. This includes configurations that are currently working under OS X 10.8.5 (Mountain Lion) and 10.7.5 (Lion). The testing was done on the Golden Master prerelease version of OS X 10.9 (13A598).

Plugable USB display adapters and docking stations use DisplayLink chipsets that send video information through USB to connected monitors. Changes in OS X version 10.9 appear to allow this process to work for only a single additional monitor- for a total of 2 displays.  Adding a 3rd display seems to create issues with the display arrangement- specifically, forcing all the displays to operate in “mirror” mode rather than as “extended” displays, and losing the software settings that relate to the physical arrangement of the monitors.  Currently, the only consistent workaround available is to manually reconfigure display arrangement whenever this error is encountered. Connecting only one display at a time may (or may not, behavior varies) help.

Support for DisplayLink-based USB display adapters was also broken in early versions of OS X 10.8, but were largely corrected in later versions. We suspect support will improve in a similar way for later versions of OS X 10.9.

For OS X customers with more than two displays- even if only one is USB attached via a Plugable dock or adapter- we recommend *not* upgrading to OS X 10.9 at this time.  Especially if everything is functioning under the earlier version you are using, the launch version of Mavericks will likely create new issues.

We will test each new revision to OS X 10.9 as it comes out and will update our blog and other information outlets when these issues have been successfully addressed. We appreciate everyone’s patience with this- efforts to resolve this issue are ongoing.  Subscribe to email updates on our blog, or follow us on Twitter or Facebook for news as it develops.
