All About Docks

The Thunder Down Under

Targus Australia made some short videos showing the versatility and usage models of the Targus Universal Docking Stations.  Check them out at Targus Universal Docking Stations CounterClockwise Perspectives .  However, it is still not clear if USB data flows clockwise or counterclockwise down there. DocKtor Out!

Monitors Galore

The DocKtor often gets asked for ideas on how to connect more than three monitors (in addition to the one native to the PC and two native to the dock).  Most application requests are for four external monitors, and some as many as six. By connecting one Targus USB3.0 SuperSpeed Dual Video Adaptor model number ACA039US ($99.99 SRP) to one of the Targus Universal Docking Station USB3.0 ports, and additional two monitors […]

2.4GHz ISM Band RF Interference from USB 3.0

The good news is that the DocKtor hasn’t heard of too many instances lately where RF devices (wireless mice and keyboards, headsets, etc.) fail to function consistently when coupled with workstations using USB3.0 devices i.e. Targus Universal Docking Stations.  It appears that modifications in the universal docking stations and consideration of the issue from RF device manufacturers has lessoned the instances of the annoyance.  The issues do seem most prevalent […]

Universal Docks Are USB Devices

When I first started using a universal dock even I, the DocKtor, had trouble getting my head around the difference between using an old fangled snap-in proprietary dock (sometimes called a “port replicator” – example below) and using a “universal dock.”  This wiki (http://en.wikipedia.org/wiki/Universal_port_replicator) is pretty good at explaining the difference, but it is important to remember that a universal dock is actually a “USB Device” containing its own hardware […]

Macbook Users Unite

Was the release of “Mavericks” any better than the release of Windows 8.1 Preview? Not for the DocKtor! The DocKtor was content with the functionality and performance of his Targus docks with OSX Mountain Lion 10.8.5, but like most thought a free upgrade to Mavericks 10.9 could only improve the experience. Boy was the DocKtor wrong, see http://www.displaylink.com/support/ticket.php?id=354 . With all due respect to the “Apple Biters” (the DocKtor also […]

Slow Docking? Check the Device Installation Settings.

Activity Based Working (ABW) or “Hotelling” has highlighted a Windows setting that delays connection of USB devices while drivers are downloaded from the Microsoft Windows Update Server. Changing the Device Installation Settings will prevent this unnecessary delay each time you connect to a “new”, or different docking station (or any other USB device with a new device ID) or connect a docking station to a PC’s USB port not previously […]

Display Data Channel DDC Dock Support

Alas, the Targus Universal Docking Stations DO NOT support DDC/CI for modifying monitor parameters like brightness, contrast, and color calibration. If color calibration is needed, it is recommended to calibrate the monitor using the local PC’s external monitor port and then connecting the monitor to the dock. The feature was in the original DisplayLink DL-1×5 family, but Targus now uses the DL-3xxx family. DisplayLink found little interest in the feature and […]

MTU Size Matters

A large government (no this is not a Democrat vs. Republican argument) customer found that some of their remote users were having problems logging onto internal web sites over VPN when using the Targus Universal Docking Station’s GbE port. If they used a local PC Ethernet port or wireless Ethernet, things were fine. What was eventually determined was that the MTU size for the Targus dock is 1500 bytes (default), […]
