I decided to shine the light from my iPhone onto my iMac's screen while it was off, so that I could clean off any dust and stuff using the cloth that came with it. Has anybody else done this? When shining the iPhone flashlight on the turned off screen, there is no way to make it look perfect. There will always be another speck of dust, and there will even be (I assume this is normal) a micro-scratch or two on the surface of the glass (the kind of micro-scratches that gold can develop when used). Obviously there is absolutely no way of seeing these using any methods whatsoever while the screen is on, so it's not really a 'defect' but it's a rather terrifying experience to shine that light all over the black screen and look at it from different angles. Anyone else went through this?
