Pixel Streaming locked to 4k (max) resolution?

Hello,

I have a pixel streaming app that I’m wanting to show on a remote large screen. This is working fine until we get past 4k resolution 3840x - in which the web browsers (firefox/chrome) will just freeze on the stream and it will not update until we resize it back down to under 4k. Is this a limitation of the browser, unreal, signaling server, other?

Thanks
