The problem with using your eyes is that we tend to prefer brighter more colourful images which are very artificial which is why shop display TV have the brightness way up and the colour turned up to max.
I've tried proper calibration etc before but it just does not work for me - think I must just like bright and shiny!
The disappointment was in calibrating colour .I did as per the instructions and my plasma ended up with a colour setting of 46 resulting in bright red faces of people on screen , wimbledon grass was too green etc.Contrast and brightness seemd to calibrate fine , i accepted the settings but turned colour down to 30.
So, did you have the gel? What disc did you use?
Even with a gel the most you can do is set the master level for the tint and colour controls. It is not possible to do anything with the grey scale tracking with any degree of accuracy without a colour sensor and PC software. This is because our eyes constantly adjust for changes in colour temperature in the real world. They do the same when watching TV.
The next question normally asked is "Why bother with colour adjustments if our eyes compensate".
The answer is that when we adapt to make white look white in nature, the rest of the colour palette is viewed under the same lighting conditions. TVs don't work that way. The colour balance can (and does) often change across the grey scale. There will often be a predominance of blue in the upper half of the grey scale to make whites look brighter. Then there's a hump of red corresponding to Caucasian skin tones attempt to correct for the over-blue. The result is that faces end up looking magenta (too much red/blue mix) rather than natural. At the darker end of the grey scale there could be a predominance of red, green or blue or any combination depending on whether the TV was set to cool, natural or warm colour preset as a start point.
Setting the master colour level doesn't normally result in the sort of issues you seem to have unless something else has been altered incorrectly first. The most likely candidates are colour preset, gamma and greyscale or CMS settings. However, this doesn't rule out the effects of manufacturer's picture "enhancements" which often just screw up the picture.
So, what did you adjust and how?
ps just to clarify I have switched off all the manufacturers picture enhancements.
I really wonder why they bother with all these picture enhancements when you tend to switch them off to improve the picture. Saying that I know plenty of people who stretch a 4:3 picture to fill the 16:9 screen and think it looks much better like that. :eek:
Most of the "enhancements" are to make the TV's look good in the harsh / bad lighting in the stores.
Not at all, they have a special 'shop demo mode' for that, nothing to do with customer picture 'enhancements'.
