Hello,
I recently bought a dual 4K screen with a 5k usb docking allowing broadcasting on my two screens.
Everything works fine except when I put a video on youtube for example, my mouse lags. I tried to change the resolution in the settings with OPTION like many tutorials on the internet but it doesn't work. Also, I use Shadow cloudgaming. When I start the stream to connect to my pc in the cloud, both my screens start to lag (but not the screen of my mac laptop). It's really weird and I have no idea how to fix it.
Thanks for your help.
 
In fact, the more I put the application on the big screen, the more it starts to slow down on the 2 screens but not on the portable screen of my mac.
