Hello,

i try to read 4K video with vlc, but i have many lag, it's not fluid.
Do i need a special configuration for VLC ? I checked the gpu acceleration option.
it work good with Media Player Home Cinema.

Thanks,
(And sorry for my bad english)

my conf:
win 7 x64 pro, core i7-2600, ati radeon 7970, 8Go ram. I tried this with a sony VPL-VW1000ES

Try another video output module:

And/or disable/enable GPU acceleration:

And/or adjust FFmpeg threads:

You can also try to enable or disable some video options such as Overlay and/or Hardware YUV -> RGB conversions.
