My music scores are saved as PDF files to a usb stick and I open the music using Foxit PDF reader which once you have the hang of it displays music scores very clearly at what ever level your eyesight wishes although I do restrict the size to fit so that muzic sheet fits the screen myself. Foxit will display all the pages of a tune but two page scores are really the norm, more means dragging scores to view which is not so convenient.
My monitor is separate from my main PC and mounted so viewed from Tyros playing position, (I might in future run two screens from my main computer, I do have a Nvida 1060 display card on the new pc).
