Have you found the "can't even detect the device is on when displaying a totally black screen" claim to be true in practice?
>>107724310You mean if you can see some faint raised black level? Depends how well calibrated it is. Most are worn and out of calibration or were poorly calibrated from the start.
>>107724310I can still hear it anyways without looking as far 15kHz CRTs go.
>>107724337>You mean if you can see some faint raised black level?Yes. As in, when the device is powered on in a totally dark room, and displaying a 100% black screen, can you tell the device has even been turned on? Can you even see the screen in the darkness after your eyes adjust?
I have found that when I have adjusted a CRT screen to reach that level of darkness that it crushes the black levels of content I'm trying to display. Perhaps with careful gamma calibration this could be mitigated.
In a 99% dark room (night time, lights off, curtains closed, etc) I can still see a CRT screen in the dark even when it is powered OFF. Because the phosphor coating on the inside of the tube still emits small amounts of light at all times.
>>107724356Depends, a good VGA CRT that's well calibrated. No. A cheaper TV even with decent calibration? Yes.
>>107724395Only if it has been recently excited, even if externally.
