media player classic and VLC are such amazing players compared to WMP. all the built in windows apps for watching videos are crap
In MPC-HC, view > renderer settings > presentation > enable frame time correction
Guaranteed smooth and synchronized playback always.
I guess I'll try to see if I can fix it again try these steps again. I did use different players such as VLC and MPC-HC and MPV and such. Even 4k on youtube is not working for me. I had my 4k TV for a while now but my PC just ain't working right for anything 4k. It's really weird.
