Question

LCD 32inch 100htz TV can't cope with fast movement, all channels.EG fast hand and face movements esp.close up. The 3rd Tv that does this so assume signal/Yet paid for a test and the signal is apparently ok.So blurring/ juddering still occurs. I am on digital ariel but can cable/sky sort this? Lip sync also a small problem.
