I'm having a similar problem, but with certain third-party apps.

Hi Gipfel,

Depending on type of browser you use, by default on Internet Explorer, you can zoom in using Ctrl & '+' button on keyboard to zoom in and Ctrl & '-' to zoom out. If you're using touchpad you may try using pinch motion. If you're using external mouse you may use Ctrl + Scroll Wheel.

Hi shafwan2204 - Ctrl + or - unfortunately has no effect.  The website displays accurately but with text so small as to be unusable.  I think it is because the website is not optimized to display on a 4k screen.  I wonder if there is any XPS 15 setting that can fix this issue?
