Are you gonna use DTH on it or OTT or Custom Source on your TV.
Are you going to use it or say parents/family. How is the distance from the TV to your seating area? Is there a window or Door opposite your TV.
All these decide whether you need a LED/QLED/MiniLED/OLED. Also the speaker output & Input.
Personally I felt TV above 65in is useless for viewing DTH & OTT. I prefer high-res souce for it like 4KBlu-Ray Player, Android Box, GameStations, etc., The bitrate of the AV content on OTT fluctuates a lot. Forget watching Live Sports channel especially Cricket matches. I don’t have 65in TV, but stayed in Company Guest house for 3 months using Sony Bravia 65in in the Living room. Promptly connected a decent HDMI Cable from my laptop and watched Netflix 4k contents. Had a 1gbps connection too. Had a problem with the TV’s inbuilt Netflix app.
