Honest question. What's the real difference between an Oled TV and Oled monitor with the same specs? And why are monitors more expensive?

I am looking to upgrade from my G5 32" VA monitor to a oled/qled one and I was comparing prices and specs. The cheapest 1440p/32" is at 800 euros. If there are other cheaper, but quality alternatives, please let me know. At the same time, you can but a 4K/43" tcl tv with all the goodies you'd want from a monitor (hdr, vrr, 1ms rt, free sync etc) at around 400-500 euros. Am I missing something here?

Ty in advance

Edit: I am at work and just saw all your comments. Thank you for the replies. I have a clearer idea now. Im probably going for a tv since I play at 120 fps/hz
