Issue:
- not getting max refresh rate
- external monitor lags and plays high resolution videos intermittently

First things first:
1. make sure your monitor supports 144hz refresh rate
2. use the right cable, I would recommend DP to DP or USB-C to DP cable that support 4k at 144hz
3. make sure your docking station is also supporting 144hz

Now, if you still don't get max refresh rate, follow the video and you should be good.

My laptop: Dell XPS 17 9700
My external monitor: Gigabyte M32U 4K 144hz
