The Sony has 400 lines of resolution which is above the average of 300 for an LCD or OLED.Chances are if you can't pick any motion issues on your set with 400 you would not pick any on the ones with 300 either.
Ever since I updated my Denon with the DTS X firmware, it has increased the volume of DTS soundtracks substantially. I tried Collateral and The Force Awakens blu-rays and they are playing louder. Although the dynamic range on these two titles is good, they are not mixed particularly loud. I only have one DTS X title and that is Whiskey Tango Foxtrot. It plays rather loudly. Is anyone else experiencing this?
