While cleaning out my In Box I reread your query and thought although it might not totally work for you that it might be worth reminding folks like myself of a tool literally in your hand.
I often use my IPad to look at and enlarge projects through the camera app. If you then take a clean picture you can enlarge it greatly and cleanly so you can inspect your work. Perhaps Android phones and tablets are equally as good or better..... give it a shot. Just take 2 fingers and spread the image, squeeze to return.
I attached a photo for reference.
