"Banding" on Philips 9664 / Pioneer 320
First post so please be kind!
I've recently purchased a Philips 42" 9664 and Pioneer BDP 320 combo and have been very impressed up until I've noticed a strange anomoly recently.
When watching Blu-Rays output at 21:9 with the black horizontal bars at the top and bottom of the screen there appears to be a small blur, about 5-10 pixels high, only visible on lighter scenes. Is this to be expected (I've noticed a similar but less obvious effect on my dad's Sony W4500) or something that can be lessened with better settings?
