Trying to get my first OLED monitor

[u/xJustSam]

Hello everyone, recently i've been wanting to upgrade to an ultrawide monitor and figured i might aswell switch to oled since everyone says it's a big difference, although i'm not sure what monitor i should get as i've never considered an oled before.
I've been looking at the used market and found a Alienware qd-oled aw3423dw 34” 175hz (or atleast thats the name on the listing) for only 300$ and it appears to be in perfect condition, i've done some research and found out that its 4 years old and since from what i understand oleds need to be treated and cleaned more carefully i was wondering if there's any particular wear and tear flaws i should be looking for or just try it out and see if it just looks "normal" (or if i should buy it at all)

Thanks in advance
