Did you test that setting every pixel black actually triggers this? Most OS just shut the monitor after inactivity (by ceasing to output video signal, or something like that).
- stavros 5y agoYes, it happens within seconds. It's not VESA blanking.
- vbphprubyjsgo 5y agoThat's a huge misfeature, then. Is it a computer monitor? Ahh maybe you are referring to dynamic contrast (which is still a misfeature).
- stavros 5y agoIt's a computer monitor, yes. I don't know about a misfeature, I love it. What's dynamic contrast?
- vbphprubyjsgo 5y agoI have never seen a monitor that turns off with a black screen (aside from dynamic contrast mode). What happens when the screen needs to turn back on? Does it freeze for 1-3 seconds? > What's dynamic contrast? Shutting certain backlights to raise the contrast between the dark side of the screen and the lit side. It has various undesireable side effects such as the darkening and lightening giant areas unexpectedly. They often try to make the transition gradual which just makes the screen even less real-time.

No, it takes around 200ms for it to turn back on. > Shutting certain backlights to raise the contrast between the dark side of the screen and the lit side. Ah, no, there are no sections in this one, the whole backlight turns off and on.
