I don't know what UX UI is but my monitor is the same size as yours and I don't have those problems.
I believe your problem might be your monitors screen resolution is set too high. Try to right click on your desktop and go to "display settings" and adjust there. If it shows "recommended settings" try that first.
If that doesn't work check to see if you have zoom settings on your browser set wrong.
It could also possibly be a setting in your graphics card.......................
