Been adjusting again today. Using
http://www.lagom.nl/lcd-test/ I've never been able to achieve a few things with my settings to date.
1. Contrast test - I could not quite get squares 1-2 for the colour bands to show.
2. Black level - I did not see the top row of black squares.
So I've managed to now correct these. This is what I'm testing with now:
Game Mode = Gamer 1
Games Adjust > Black Stabiliser = 60
Picture Adjust > Brightness = 35
Picture Adjust > Contrast = 55
Picture Adjust > Gamma = Mode 3
Picture Adjust > Colour Temp = Warm
Picture Adjust > Six Colour = (All default - apart from Red_Saturation = 48)
I'm now seeing blocks 1-2 on the Contrast test with nice seperation on the colours up to 32 (especially on red). Although on blue blocks 31 and 32 don't seem to have a difference but I can't get them any better - adjusting the Blue_Saturation didn't help. Gamma looks right in the 2.2 range. Black level test I can now see from 3 onwards. White saturation test I'm seeing 252 and just a small part of 253. Pretty pleased but see how it goes as with Black Stabiliser up from 50 to 60 there is obviously a noticeable difference but going off the test patterns, it was too dark on 50. I was missing the entire top row.
Thanks.
