I am trying to dial in the "Standard" mode on a UN55D6000 Samsung LED driven LCD set.
I have ensured that Dynamic contrast is OFF, and balanced the color control via the blue mode on the tv. The result was "48".
When looking at the AVS HD 709 calibration disc's grayscale section, cycling to the primary color upper end section (the one just before the grayscale uniformity cycling pattern) I run into the problem of red clipping before it reaches 234.
With color balanced, I must dial the set all the way back to a contrast setting of 80. This is using the "Native" color space. In "Auto" I can squeeze a bit more contrast, maybe to 82 out of it (I am aware auto is the closest to Rec 709).
If I under saturate the colors, say dialing back the color control to 45, I can get more contrast out of the set, say up to 85.
How should I approach this? White contrast test patterns give good colorless results up until the 95 range, almost maxed, and the other primaries: blue and green can also survive a high contrast setting and a balanced color control. Red is the only one that falls short.
I think undersaturated colors and a rather low contrast setting in order to see full red detail is a bit upsetting.
Is there anything else I need to adjust to fix red from clipping?
