4k videos in Unity

Hi,

I'm trying to look into playing 3 4k videos simultaneously across 3 4k monitors using 1 single Unity build. I have achieved this using the demo version of AvPro.

However, the 4k videos playback is slow and lagging. Has anyone else encountered this using AvPro?

Or is there any other asset/method to achieve playing 3 simultaneous 4k videos?

Thanks
