Steps to reproduce the problem:
1. Extend second display. (4k Main, 2K second display)
2. Open Chrome browser
3. Observe scalling issue

What is the expected behavior?
When displays are dublicated, no scalling issue is found.
Therefore, the same scaling is expected when displays are extended.

What went wrong?
Obvious scaling issue on second display, only when display is extended, not duplicated.

Did this work before? N/A
