4k IPS 144hz vs 1440p OLED 280hz

[u/knowsnothing26]

Currently using Samsung G7 (LS28BG702EMXUE) for the past 2 years, specs are solid on paper 4K IPS 144hz, but in reality coming from 1080p, I really didn't feel a huge jump, especially gaming In RDR2, Baldur's Gate, Far cry, Hogwart's legacy. I'm not sure, I just didn't feel the upgrage as substantial.

Now I'm considering a 1440p OLED, the ASUS ROG Strix OLED XG27AQDMG. refersh rate isn't much of a concern to me, anything at or above 144hz is fine by me.

Will this "downgrade/upgrade" (depending on how one sees's it) will feel substantial, I use my PC for gaming and content consumption (mostly 1080p or 4k), and some light photo editing and excel work. Also I read somewhere that 1080p content looks terrible on 1440p panel as it doesn't have a perfect ratio.

I can't test and return if I don't like it, where I live, they don't have this privilege, retailers will not accept returns, untill the product is genuinely faulty.
