Need help figuring out what to buy next.

Hey guys im new to OLED in general. I was rocking a dual monitor setup for awhile now and i figured it was finally time to bite the bullet and see what the craze was all about. started off in a budget to get my feet wet and replaced my main monitor with a 27" 240hz aoc oled. its fucking awesome so far and i love it. that being said in thr future maybe come cyber monday i would like to by a new oled monitor to be my new main monitor and move the 27inch one to be my secondary.

soooo what im looking to get would be something in the 32-34 inch range. 1440p or 4k and if i can something higher than 240hz if possible but not entirely necessary. mainly its just a bigger screen without loosing any refresh rate.

budget ideally would be 500-700 dollars and im willing to wait for sales. Just wondering what are my best options! thanks!
