10 Hours Grey Screen - Monitor Uniformity and Backlight Bleed Test

Something to put on and leave: one colour, full screen, nothing else. The picture is a single frame: a screen of solid grey. It does not change for 10 hours. Completely silent - no music, no background noise. What it helps with: a steady reference while adjusting monitor colour mood lighting for a room coloured fill light for photography and video turning a second monitor or a TV into a backdrop a background for streaming and filming soft light at night that does not glare How to use it: Turning screen brightness up makes the light stronger without changing the colour. Go full screen (press F) and wait for the player controls to fade - then only the colour is left. Turn off autoplay so it does not jump to something else at the end. If you are watching on mobile data, lower the resolution - the colour stays the same. Questions people ask: Is there any sound? None. It is completely silent from start to finish - no music, no effects, no background noise. You can leave the volume up and hear nothing. Is the colour exact? Video compression can shift a colour by a unit or two; that is true of any video and it is not visible to the eye. For precise work like colour measurement, use a calibration tool. Why so long? So it does not run out and jump to something else. It should last a whole night, or a whole shoot, in one go. Are there other colours? There are a good many on the channel and more going up. If the one you want is not there, say so in the comments and I will make it.

Length, tone, picture - all of it can change. If this one worked for you, a like and a subscribe genuinely help - and tell me in the comments which length you need next, because that is where the next one comes from. #greyscreen10hours #backlightbleedtest #cloudingtest #displaytestpattern #fullscreengrey
