I know there are some older mentions of plasma. I just bought a LG 60PM6700. it's massive, anyone have setting recommendations?

Never had a Plasma so not sure if the same. In the settings turn off any digital processing such as noise reduction, motion smoothing, adaptive brightness, colour enhancement, anything that says automatic. Reduce sharpness to zero. Might be best to take notes on what you've changed. Especially if it was ok with your eyes before you started playing with the settings. That way you can change it back. Also resting to factory defaults can undo bad settings a previous owner did.

I have an ancient panasonic plasma (its on right now) and the default "Cinema" picture profile works great for me

I am considering purchasing a used Plasma on eBay. According to Wikipedia:

The lifetime of the latest generation of plasma displays is estimated at 100,000 hours (11 years) of actual display time, or 27 years at 10 hours per day. This is the estimated time over which maximum picture brightness degrades to half the original value.

I am guessing there's no way to know if the owner left it on 24 hours a day forever?

And what happens after 27 years, the display simply gets half bright, but still probably usable with extra lighting?

    We have a early 2000s vintage 720p Samsung plasma and its fine. Still going strong and no eye strain. We use it with an Apple TV 4K.

      Most things can be repaired too. With Tv's, capacitors can swell and stop working after a decade or two. Usually in the power supplies. It's not too difficult to replace these if you can use a soldering iron. People in the retro gaming community are keeping their old box style CRT's going by recapping them.

      Also this thread has got me curious. I'm picking up a $45 used Panasonic Plasma from FB Marketplace tomorrow. I'm hoping the smooth motion they are meant to have might make my Nintendo Switch usable again.

          thorpee I believe the aging/dimming issues with plasmas has to do with the panel itself, not the failure of any discreet components.

          That said you could always pick up a broken younger plasma and try to fix it. I am repairing a Tivo box as I speak since XFinity boxes trigger me

            Interesting, I found the AppleTV 4K produced eye strain on my good Plasma TV, so I've stuck with my 4th gen AppleTV.

              thorpee they have a very slow response rate, so they're not great for gaming.

                My LG will show you the total elapsed time. I'm sure the panasonics will too. Make sure to check for burn in. mine has some which im trying to fix with jscreenfix, but it doesnt seem to be triggering symptoms. i'll be on the lookout for another smaller one.
