55” and up. Wall mount it. You won’t regret it. Safety for the tv if nothing else.
The curved screen is a total BS gimmick. Avoid.
Yes, a smart tv: it will be so easy to shoot your videos to it. You can use your lap top to do it, but even your phone.
Best place I’ve found for Wall-mount prices is Monoprice.
www.monoprice.com - You’ll pay $35-$55 for full-range mounts that hold up to 170lbs. You won’t get ripped off by Box stores like Best Buy paying $150 for an equal mount.
