I've upgraded to a new Aspire V17 nitro 4K Ultra HD. I've had trouble with small text in Lr CC (fully updated) on the Aspire. I got around some of the small font size using Windows 10 settings. But still a problem is in the dialog box that opens when emailing photos from Lr directly. The photos appear so tiny they're not discernible. The icons for setting text appearance in the message area of the email are tiny as well and appears partially blocked out by the upper left portion of the box where text is written. Also the pointer actuated tools in Develop mode are tiny and barely discernable. I hope I made that understandable enough. This is not a problem in my old Toshiba Satellite laptop that has Lr CC as well. Enclosed screen shot of the email dialog box.
