Platform: 9901.77.1 (Official Build) stable-channel guado

Example URL:

Steps to reproduce the problem:
1. When playing video on a 4K display video playback is lagging
2. Writing on the touchscreen becomes too slow on 30Hz. The line is following your hand too slowly.
3. 

What is the expected behavior?
No lagging in video playback and while writing the line must move faster.

What went wrong?
ChromeOS automaticcaly runs on 30 Hz with the 4K setting

Did this work before? No 

Is it a problem with Flash or HTML5? N/A

Does this work in other browsers? N/A
