I have a Belinea LCD monitor next to me which, when it has no signal (for instance when the computer goes into DPMS screen-saver mode) flashes the whole screen red, green, blue, white and black in repetitive sequence with a period of about two seconds. It's only been doing this since yesterday. Has anyone seen this before, and is it something I should expect? Perhaps it's to make me switch it off when I'm not using it and save electricity.

Not long ago, this monitor was attached to my main Solaris workstation. Every time I came in of a morning, I'd press a key to wake the machine up and then spend several minutes looking at a blank screen waiting for it to warm up. When it was nearly ready to come on, the orange light would blink for a while, and then go green when the screen appeared.

I did the following experiment: I switched the monitor off, and then only switched it back on again after I'd woken the machine up. It still didn't come on immediately, so I somewhat foolishly reasoned that it was the machine's graphics card that was playing up, rather than the monitor.

Over a period of a few months, the waiting time gradually got longer, and one day it topped 15 minutes. So I decided to switch monitors, and discovered that it had been the monitor's fault all along. Oh well.

Anyway, this goes to show that the monitor was already loopy. But it never flashed colours at me until yesterday when I moved the connection from one PC to another.
