There can be some jerking - or perhaps more accurately, double imaging - with 50Hz PAL material, but this is only seriously distracting under very specific circumstances, such as when a camera pans over the lines of a football pitch. Plus you can reduce the problem considerably if it’s troubling you via the set’s Intelligent Frame Creation system - though if you do this, make sure the frame interpolation isn’t set any higher than its Mid setting if you don’t want pictures to start looking painfully processed.
Obviously, this isn’t the first time we’ve drawn comparisons between Panasonic TVs and the legendary but sadly now extinct Pioneer KUROs. But with the P42VT30, the comparison is particularly justified, since we’d say the depth of its black levels really does finally tally with that of the last KURO set we tested. Dark scenes contain areas of blackness that really can look as black as the bezel around the screen, or the inky darkness of a blacked-out room.
