glad to know that there still are plasma tv users.
how would you rate the pq of your f5500 vis-a-vis the c9?
Let me put it like this ....
The LG is obviously much better if seen side by side with the plasma. Its a different beast.
That said, even without HDR and significantly less processor capability, I still don't mind watching 2k or 4k content on the plasma. In fact, I still occasionally do so, because on a stand alone basis, it's still an excellent TV. The colour balance is very natural, there's no eye strain and it's just a joy to watch, no question. Also, for the past about 4/5 years, it's being used about 70% of the time with PS 4 & 5, with nil image burn in.
In contrast, nowadays I simply dont feel like using a couple of LCDs that I have (a Pana and a Samsung ... both 12+ years old and in perfect condition), because the pic is just too "in your face", if you know what I mean.
In a world with no OLED, I'd still be very happy with the plasma, notwithstanding the heat generated and the power consumed.
Hope this answers your query.
