A:AnswerDanny, you would need an RCA to HDMI converter. It is available on Best Buy's website: https://www.bestbuy.com/site/insignia-rca-to-hdmi-converter-black/6134312.p?skuId=6134312 ^Gina
A:AnswerIMO this is one of the best values for a bright TV. I have it near a window in a second bedroom for guests and never a problem seeing during the day. My other Samsungs for movie viewing are the QLED 80 series and I will say I am impressed with this little guy! Took a side and head on so you can see.
A:AnswerSpecs say about 30 lbs. You'll still need 2 people to handle setup as it's still too bulky for 1. Great picture, but sound from speakers a little weak
A:AnswerYes you can add new apps. Comes with a few preloaded but we added Disney+, HBOMax, Discovery+ etc. So if a new app comes out in the future you would be able to add it.
A:AnswerI have mine hooked up to their DVR, so I don't know about the app. Have been told I can put the app on TV, but can't figure out how to do it, so can't speak about that. But supposedly, yes, you can use the spectrum app on this TV.
A:AnswerYes, but you will need to purchase a mount separately that meets your needs - flat, tilt, etc. Any common mount should work as the mounting holes on the back of the tv are standardized.
