As a software developer I insisted on buying a 4K Monitor which used to work with my previous MBP 2017 quite ok.The Retina MBP Late 2015 has output that lags quite a bit when I use a scaled resolution.
The output is only OK if i try the 4k or 1080p resolutions which are not very optimized for reading things on the screen.
Is there any way to optimize this? The lagging performance can be seen when I do something with Java VM especially Android Studio.
I connected my mac book over mini display to display port since HDMI does not support 60hz. Lag means when you scroll the code editor in Android studio, it is not very fluent.If i type something there is a small time gap till i see the letters appear on the screen.
