Turning off automatic screen clanking

Hello Timothy,

My monitor (Iiyama Vision Master Pro 21) turns its power off as soon as it realizes that the screen was staying black for a certain amount of time (configurable). It hasn't anything to do with power management stuff, since I can also reproduce it by turning the cursor off and then typing "clear; sleep 10000000" in my shell.

That's why I appreciate the kernel console blanking.

Although I suppose it would do the same if you just cycle the colors, since the monitor shouldn't notice the difference. But you would have to cycle the colors to black, I guess. "very dark grey" would probably not be enough.

And then I see no point in cycling the colors instead of blanking.

My old monitor, Iiyama VisionMaster Pro 400, was meant to do this too, but it never worked. It only ever went into power saving when the distro I had installed set this option during boot. Up till then I'd simply believed the kernel config help where it mentioned not doing power saving and so never looked for the option! Up to then I'd only had DPMS available through X.

BTW, I assume you have screen blanking and power saving disabled by setterm when the monitor goes into power saving mode?

The idea is to save your screen from burn-in AND be able to read it at the same time. I wasn't considering power-saving. If you keep changing the colors on the screen but maintain contrast between characters and the background, that would do the trick.
