I think this may be the first ever sub-$2000 75" 120hz TV? It's from the Sony seconds store though I've ordered from there before and I swear the TV was brand new.
This is supposed to be Sonys flagship 120hz TV for the PS5. Not all features are available as of yet (VRR being the main one I think), though Sony are saying they will release an update.
Great TV for people with a PS5 or Xbox Series X.
