When I started using my LG 34UM95 monitor it was effectively a secondary display, my principal one being an Apple Thunderbolt 27”. I have been sufficiently pleased with the LG to promote it to a primary role to make use of all that glorious screen real estate. I used the supplied HDMI cable to connect monitor and computer.
The LG provides three USB ports (one 3.0, two 2.0) and I not unreasonably wanted to connect my keyboard (why Apple doesn’t offer a wireless keyboard with numeric keypad is beyond me) and Apple DVD drive using the LG’s ports. That’s when the problem started.
I connected one of the Mac Pro’s USB ports to the LG’s USB up port, but my keyboard just would not work through the LG and after a short while I observed a dialogue advising me that a USB device was drawing too much power.
The answer was simple, though. I dived off to my friendly Apple supplier and got a Thunderbolt cable. I connected up and bingo, USB ports all working, monitor and Thunderbolt connection recognised and automatically configured.
Mind you, I thought thirty-five quid for a 2 m cable was a bit steep, but Thunderbolt cables are not exactly ubiquitous. Imagine my surprise when I saw on the Apple Store an optical Thunderbolt cable at the bargain price of just a quid short of a grand.
That’s right, £999. It is 60 m of the finest optical connection, to be fair, but I would love to know how many of those get sold each week.
