This is not the move to make. I've been down that path. The best thing you can do when you buy an expensive TV like an OLED is take several years off and not pay attention to what new TVs come out.CX was overpriced simply because it had zero competition
The C1 actually has higher peak brightness, so I might sell the CX and cop that this year, and the also have a BUDGET OLED the A1 releasing this year, depending on how that performs the CX might already be obsolete
It's likely gonna be difficult to re-sell a TV like the CX anyway and get fair value. TVs depreciate very fast. The real issue is the CX isn't a value purchase. The kinds of people that want to buy a CX likely have the money to buy them brand new or buy the C1.Unless you trying to sell that for $700 or less people not really trying to take a hit on the warranty and face potential burn in on a used OLED like that. Put in on FB Marketplace and watch the offers be lower than that.
