Mick, I see no one has replied so far, so here goes.
Has this only been noticed recently?
“the skin tones always look slightly blurred” – Look at some finer detail in the picture. Is this also blurred?
Is the picture better when viewing quality real time news broadcasts?
Many transmissions via Sky and Virgin Media can leave a lot to be desired, especially older transmitted material.
The scart lead gold plated pins or otherwise will not affect the picture focus.
The 8ms response time should only affect fast moving images. A fairly still picture should not be affected.
Maybe the VM box is faulty.
I use VM for my broadband and phone, but I use a wide band chimney mounted aerial for my TV signal.
Is it possible to test the TV on a good terrestrial aerial?
