It would help if you gave a brand and model, and if it's new or used.
From what you said, it seems you got ripped off, but it might also be something as stupid as using an old cable which is drastically limiting you and a cheap and easy fix.
It is a new Acer CB272K. Using the HDMI I got with it.
Not sure what you mean, but look at what you have, and look at pictures of what it should look like from places that aren't selling it
If it is the same, then it sounds like the issue is you need to adjust settings on your computer, make sure all the settings are right in windows and any software for your gpu. You may also need to download some drivers from Acer.
But you can't just plug the monitor in and everything maxes out, make sure you've enabled everything, then circle back and test and see what's still working.
Framerate is a common thing that needs enabled too. Lots of people get it flipped for various reasons and just don't notice the only thing limiting them is a setting.
