Advice on selling G1 or trying to find a used one to match?

Basically setting up a media room, with two large displays. Ideally would like them to be the same screen (simultaneously watch the same movie, gaming, etc, and want minimal to no variation in quality).

I currently own a LG G1 77 inch, its in fantastic condition, despite it being a 2021 model, it prob has less than 200 hours on it.

Wondering if I should sell it, or try to find (having a hard time though) another 77 inch G1.

PS - if I go the sale route - , Im in the Columbus, OH area if anyone is interested and wants pics, DM me.

Thanks in advance everyone, have a great upcoming weekend.
