Bugs while working with External Monitors

[michaelsh]

When I open Power BI Desktop on external monitors sometimes when I click on a certain menues, buttons it doesn't react.

It is not stuck - when I change the Display setting to "Duplicate" then it is working alright even without re-openning the app.

I have two ThinkVision T24i-2L 1920*1080 monitors (set to 100%) and Thinkpad P1 Gen 4 laptop with 16'' 2560*1600 (set to 150%).

I've found this post with similar issue: 

https://www.reddit.com/r/PowerBI/comments/db8wve/display_issue/

It recommends to "Disable display scaling on high DPI settings".

What does it mean? I don't want to ruin something else, my problem appears occasionally.

Please explain how it works

Hi @michaelsh ,

When you use a high-DPI device such as a Surface Pro 3, Surface Pro 4, or Surface Book together with external monitors, you experience the following issues:

• Elements such as applications, the taskbar, icons, toolbars, text, and dialog boxes appear to be fuzzy.

• Elements are too large or too small compared to the rest of the desktop.

• Blurry text appears in applications or in the Windows interface.

Although these symptoms may be seen on a single monitor, they're more common when you use multiple monitors that vary in display resolution. 

Solution:

Match screen resolutions Consider deploying monitors that have complementary screen resolutions.

When you use multiple monitors (including when you dock or connect to remote screens), a greater difference in the resolution between the native device and external device is more likely to cause the issues to occur. For more information, see the following OneDrive presentation:

If I have misunderstood your meaning, please provide more details with a screenshoot.
