It baffles me why some should end up with a micro display and others an oversize. In my case ( 15in laptop ) I have not had any problems with width. Length is variable and scrolling down is sometimes required. I use Lightroom CC and on export I can set the pixels ( say 1000 ) for the longest side. That is fine for width but, if in portrait mode, the pixel count would have to be reduced considerably. I use Windows 10, with Microsoft Edge browser.
Cheers,
Mike.
