It would be good if everybody could agree on everything but it would be a very boring world.The truth is a compromise,and no more so than with a TV set .
What is a good TV picture,what ever makes you happy,the calibration of a TV set inst done in a laboratory it is done at the end of a production line.
On a production line its one done where is the next there is no time for opinions and discussion.
In the days of analogue signal quality played a major role in picture not with digital,the picture is either there or not,but some tellies can have a lot of noise int he picture giving the impression of grain or snow of an analogue picture.
We all see colour differently,motion differently.
What do you mostly watch on TV soap operas,gardening,natural history.
If like me you grew up with gardens and gardening then you tend to be very selective about TV pictures,and can quite easily become a bore.My brother loves to wind me up diving in and and attacking my TV picture,of course I will always run his picture down,who is right and who is wrong, we both are.
