I am delighted with the TV, it is large without being imposing, for £421 (over 5 months 0%) I really can’t complain.
I find it hard to believe there are levels of picture quality above this, i’m not sure my eyesight would be up to it. I have not moved beyond the standard setup and it seems to fair well in all conditions. Thank you again @Kezo, I would not be £421 poorer if it was not for your expertise.
