Are we in a quantum entanglement?
I was in a very similar dilemma.
I recently moved to a new apartment which doesnt have enough space for a 4K TV and an HFR Ultrawide 1440p monitor on a separate desk.
I had to choose one to keep.
I eventually decided to go with the 4K panel.
Yes Im not maxing out the refresh rate (i5-12400) but im still doing alright.......is the 4K panel better than the 1440pUW there is a noticeable bump more so for productivity than in gaming, but that might just be because I was used to gaming at 1440pUW and when I switched to the 4K panel it just became normal after a while.
And If I want that Ultrawide feel again, I just set a custom resolution.
My home setup is an embarrassment because when i need to do "serious" PC'ing I have to bring out my angle/stand seat.
I didnt even know these were a thing until I had this problem.
^ Not this exact one, mine is some offbrand shit I found at an office supply warehouse, but its pretty much exactly the same.
