For some reason, Microsoft still hasn't got this feature called DPI Scaling correct. I think the Y520 defaults to 125%, which looks like garbage in my opinion.
To resolve, right-click on the Desktop and go to the Display Settings. Change your Scaling to 100% and reboot. All of the icons and text shown will be sharper, but also a bit smaller. 100% is native scaling to the 1080p display.
