Well, shit kinda got out of hand, and now I have three 4k monitors on my desk.
I didn’t intend for this to happen. What happened was I thought that one of the monitors that I use for my computers on the bench and in the booth was broken. So I hastily ordered a replacement. Then it turned out that that monitor wasn’t broken — the power cord had fallen out — but by the time I had discovered that eBay was telling me it was too late to cancel my order.
So for a lousy AU$250 I now have a third monitor attached to my primary workstation. Since I have pretty much no need or use for a third monitor what I have done is create a desktop background image for it with a bunch of reference material.
