Part 1: Can VLC Play 4K Movies

VLC is an open and free source platform that incorporates the capability to support playback of DVDs, CDs, audio CDs, VCDs, and various kinds of media protocols. It is a widely used media player and video converter. To be honest, VLC has added the support of 4K playback since the early years but the performance is not that satisfactory indeed.

It is very common to come across the issue that when you stream 4K movies on VLC, errors such as stuttering or lagging will happen and interrupt your movie experience.

First of all, make sure your VLC is the latest version, which means VLC developer has already resolved some issues and ensure users will be able to play 4K movies without disturbance.
Secondly, if your VLC still fails to play 4K movies, you may need to take some actions to enable GPU acceleration or increase your cache value, both of which are practical actions to allow you play 4K movies within VLC.
