Inch, resolution and rig all have relationships.
1080p max size for best visual is 24". Anything more become obvious blurry.
1440p max size for best visual is 32". Anything more become obvious blurry.
4k max size I think is 49". Anything more become obvious blurry. Then again, no one use 4k for serious gaming, is more for productivity activities.
27" with 1440p is a trade off between detailed visual and peripheral vision
To get stable 144hz on 1440p will need high end rig, basically at least like 2080
Of course you can get cheaper GPU if you willing to drop the graphic setting but come on, what's the point of getting 1440p if you gonna drop your graphic settings.
