Hello, as we have been rolling out more 4k, high dpi monitors across the company we have been hearing complaints about the crispness of the browser experience. I can confirm this issue exists in your tabbed browser example you package with the install, so I suspect it is not our implementation. I have screen shots I can send along if that is helpful. The effect is subtle in my opinion, but some users seem more sensitive to it than others. To really see difference load same page in chrome and put next to the wpf tabbed browser example. The monitor I am testing on is 3840 x 2160 with 150% scaling on windows 10.

Hi,

High DPI is already automatically enabled through WPF. Do you see the same issue on other text elements in the same application?

And yes, you can send screenshot files to us through our contact us page and we will see what we can find.

Thanks!
Chris

Will do, thanks. Hard to say.... I don't think so but you stare at this long enough the eyes play tricks on you.

I've figured out how to "fix" the blurryness, and reproduce, at leas ton two machines I've tried. Its if you have two monitors, with different scaling. In my particular example I have a laptop with 100% on the sreen, and a 4k monitor with 150%. Very blurry. If I change both to 125% and restart PC, sharp as a tack.

Ah! Thanks for sharing. That makes sense. We use the scale factor on the "nearest" monitor. We will see if we can support multiple monitor with different scaling factors.

For the WPF distribution it may be relevant to look at the updates introduced in .NET 4.8 which improves High DPI support for applications with hosted HWNDs
