re: Worth it to try to sell old Plasma TV?

I'm still on my 2013 Panasonic ST60. It doesn't get as black as OLED, but at least it's uniform near black and doesn't have the banding and crush you have to trade between when setting OLED brightness. I do have an OLED tablet, the new Samsung Galaxy Tab S4 10.1" 16x10, and I find myself doing a fair amount of viewing on it. It's nice, but they crush RGB 0-7 and video levels 17-20 or so to get perfect blacks. There's an app called Screen Balance that allows you to ameliorate this, but it's a trade-off between perfect black and uniformity and banding near black just like with the larger panels. I ended up accepting crush of RGB 0-4 or so, and for video, levels 17 and 18. Looks great with almost all material, but it ain't perfect, and I'm not eager to go through panel lottery with a big TV. It's a lot easier to return tablets, which I did twice before concluding they're all about the same.
