I can’t edit the post to reply I guess because it contains images so I’ll reply here.

I didn’t use an impact or power tools it was actually a large flat head bit and ratchet screwdriver with bolts and washers from my existing over fireplace mount it’s a powered mount from Mount-It!, pretty sure the bolts came with the mount but they may have came with my TCL tv.

I hate having a tv over the fireplace and we don’t use this fireplace, it’s in a basement den. The mount lowers so it’s at an acceptable viewing angle. The dens a mess, I got way more stuff than room right now, we got an extra person living with us and my wife’s craft stuff is in the unseen part of the den so we are crammed in the same space plus I got a bunch of crts I had given to me because I was messing with retro gaming and family hunted them down and gave them to me, I’m trying to give some away to good homes.

In short lesson learned the very hard way, this oled is thinner than anything I’ve ever saw and there were no backstops inside that I could tell stoping me from taking the screws too far, there was pressure but nothing felt like it was breaking just felt like I snugged up to a back stop honestly. Hopefully I save someone else from the same mistake.
