daily adjusments are fairly simple. use the
PLUGE pattern for Brightness & contrast en make all bars the same intensity with blue only switched on. if you use a EBUcolorbar the whitebar will appear brighter
PLUGE stands for picture lineup general equipment.
it's a signal which generate a bar which goes just underneath black and a bar which goes just above black level. another trick is to put your monitor in underscan and look at the bottom of the screen. under the last line's of active video you wil find a little blackbar just in the middle of a line. when you adjust your brightness on your monitor you must find the point that you just don't see this bar. the contrast adjusment is a bit subjective but it should not clip. in the white's
some cards will not display the under black part of the PLUGE signalbut the serration pulses discribed above should be there all the time
