This post also shares how Stellar Repair for Video can repair 4K videos if they turn corrupt and don’t play in any media player including VLC.
Recording high-definition 4K videos is the new norm. You have all the latest cameras — DSLRs, action cameras, drone cameras or even mobile phones — supporting 4K resolution.
The 4K UHD video content is gradually making inroads into TV channels and streaming services such as Netflix, Amazon Prime Video, Sling TV, and Hulu etc.
In such a scenario, you would want your highly compatible and thus favorite VLC Player to play all your 4K movies and videos. However, several VLC users complain that they cannot play 4K ultra HD videos in the media player, with lagging and stuttering reported as common issues.
So here, we bring the various methods you can use to fix VLC 4K lag and play high definition videos in the media player.
The VLC Media Player, in its latest version 3.0, comes with better support and capabilities for playing 4K UHD videos. Therefore, the first step to fix VLC 4K media playability issues is to download the latest version of VLC 3.0 Media Player and try it out to watch high-definition videos without any disturbance.
This method works when your 4K UHD videos stutter or lag in VLC Media Player. Try increasing the Cache Values in the software settings.
Note: If you do not find Cache option in your VLC Player, update it.

|Tip: you can also change Network caching (ms) and Disc caching (ms) to higher values and check which one setting works best to fix 4K videos issues.|
For many users, switching the video output to DirectX DirectDraw or OpenGL makes the 4K HD videos playable in VLC Media Player.
Steps to change Video Output settings in VLC Player:
With hardware accelerated decoding, the task of playing certain videos (usually H.264 MP4 videos) is taken off from CPU and handed over to GPU of your computer. VLC Media Player can use computer’s GPU to accelerate decoding of some type of video codec streams. If you are facing video problem in playing any 4k video file in VLC, try once by disabling the hardware-accelerated decoding.

One way to fix video lagging while playing high-definition video files in VLC is by changing ‘skip h.264 in-loop deblocking filter’ setting to ‘All’. Although this will lower the video quality but make the playback smooth.
Steps to change ‘skip h.264 in-loop deblocking filter’:
You can update graphics card drivers by using Windows Update feature. Simply go to Start menu. Click on Settings > Update and Security and click Check for Updates button. This will automatically perform regular Windows Updates and also check for new drivers.

You can directly update drivers by visiting the manufacturer’s website and follow the graphic card driver update guide. For instance, Nvidia users can refer Nvidia Update from here.
Even when your computer meets the intensive graphics and processor requirement, large-sized 4K videos may not play in VLC. You can compress your videos to a smaller size with the help of online video compressor tools.
These tools can convert and compress 4K UHD videos like H.264 MP4, MOV, AVI, etc. to HD format for smooth playback on VLC Player.
None of the above methods worked?
Then your videos might have gone corrupted. To rule out the video damage or corruption issue, try to play them in another supporting media player like 5KPlayer or DivX Player. If they still do not play, then you need to repair your 4K UHD videos with a secure video repair tool such as Stellar Repair for Video.
