As I’m sure everybody recalls with a shudder, I bought a RAID machine that had only VGA out, and I wanted to gaffa tape a 10″ monitor to it (just to make future debugging less inconvenient).
The monitor seemed to be dead, so today I got a new one, and look! It works!
So this is the VGA to HDMI dongle thing, doing its thing. It’s nice when things work.
