Even when I adjust brightness from lowest to highest I can only see max 2 bars on each outside
When I try and adjust contrast using the same pattern, I'm not sure I see anything.
I don't quite understand what I should look for using the ramp pattern/
What about colour, tint, red, green and blue bias and gain? Very confusing.
When I look at blue first it appears pretty good without any adjustments, red and green were close as well.
Sharpness. I see no difference no matter where I set it from lowest -something to highest so I left at 0 in the middle which was the default
I'm using HDMI cable connected to PS3
Brightness: Depending on the source, you sometimes won't see the darker outside bar. So you have to use the next darkest bar. Turn down darkness until you don't see the dark bar (but still see the lightest bar). Then, turn brightness back up until you just see the dark bar. You should see the lightest bar clearly, and barely see the darker bar.
Color: Check with the blue filter first. If you're using the DVE color bar test, just make sure all the blue squares are the same shade of blue.
Tint: Using the same blue filter and color bar test make sure the inside boxes at the top are the same shade as the inside boxes at the bottom. If you perform both functions right...all the boxes should look the same shade, for the most part.
Then check with the red filter. If the red filter shows the inside boxes a brighter shade than the background, that means red is saturated too high. It is recommended to lower brightness down to the point where the inside boxes are close to the same shade as the background. This will probably mean re-adjusting tint (by making sure the box at top is same shade as box on bottom).
Sharpness: If you see no difference, you probably don't need to turn sharpness up at all. The DVE does a good job explaining why "sharpness" is not necessary in most TVs.
