I posted this to reddit but I'm more likely to get a reasonable discussion on here. [VIDEO] Dave covers "static" turning off a monitor in this video. Could it be this?

There is an old EEVblog[1] video on the topic. Mine doesn't do it from chairs, but it regularly blacks out if I turn on the nearby LED strip. [1] [VIDEO]

It looks like the youtube embed is broken. It is supposed to link to a EEV blog video. It is wild how many times someone brings me broken equipment and it turns out EEV blog has already investigated the same issue for the same device. [VIDEO]
