Surprise twist: It wasn’t the monitor.
Last night I had my PC running in Windows 11 and per usual, left both monitors on, with the screensaver running to blank the screens. Shutting the right monitor off would result in it acting flaky for up to half an hour before it would settle down.
This morning, the right monitor was acting flaky, anyway. I described the issue, which included the power button being ignored when pressing it. Jeff said that seemed funny and it occurred to me to try plugging in the power adapter from the other monitor. The “bad” monitor immediately sprang to life.
The fix is a $23 compatible (hopefully) power adapter, which should be here in four days. In the meantime, I’ve temporarily replaced one of the monitors with my old 24″ one and the part that bugs me is not so much the size/resolution difference (though 24″ seems really small now), but rather the colour/temperature difference. I’ve made enough adjustments to the 24″ monitor that now the 27″ looks funny.
I should probably just go outside for a walk.
But at least I don’t have a dying monitor, as once feared.
