The TV mount is different on the 2020 and 2021 North Points, probably on the Pinnacle too.
The 2020 NP has the tabs that RDTC speaks of. On the 2021, the TV is held in by friction and its own weight on a Keystone bracket. Just wiggle it a lot from the sides while applying upward pressure. I was surprised at how much force it took to "wiggle" the tv up.
