Hardly to say, because normally it’s not a hardware problem.
Your screenshots here seems rendering pretty fine, just like my Manjaro.
Maybe you could make a test with another monitor or change the resolution of screen to see if it’s better.
In my case, the infinality-bundle satisfy my requirement, not as good as ubuntu, but it’s clear enough.
That sounds like you’ve set your screen to the wrong resolution, or you have a rare BGR-ordered screen (most screens are RGB-ordered). I have a Philips-based LCD monitor (on another machine) that is BGR and with a default setup fonts do look pretty bad.
Of course, your cable might be loose. That’s the simplest thing to check (assuming you have a desktop PC and not a laptop). You could also have mentioned what hardware you have.
I know you’ve included screenshots, but for display issues a photo really is best.
