Can only speak as I find. Previously owned a Pio 436XDE, Panny VT50 and Panny ZT, all suffered from DSE to a certain degree, plus line bleed of course. The ZT was probably the best in this regard but not perfect.Appreciate yours and Inferno’s replies.
I’m surprised to read your Panny ZT had DSE. I’ve owned multiple Panasonic plasmas in the past (albeit with a maximum screen size of 50”) and all had perfect screen uniformity.
