Out of curiosity, do you see much color shifting as you alter your head position?
Looking at it 90°, everything seems fairly balanced from top to bottom (looking at solid colours) though there is a very slight gradient in the last top 4/5cm of the screen where the colour gets a little darker.
Looking at the screen from below it becomes visibly darker quite quickly, whereas looking from above the angle is a lot greater before it becomes visibly lighter. I don’t often use a trampoline when working at it though, so no real bother there.
When these monitors first came out they got amazing reviews from top industry reviewists and were hence in high demand. To fill that demand Samsung apparently sub-contracted the manufacture of the LCD display components out, and unfortunately that means that not all 226BW’s are the same. There is a way to tell who manufactured the display by some secret OSD menu button tapping. Mine definitely wasn’t made by Samsung, so perhaps the very slight nuances I have with it are because of that.
