Solved! I am trying to display my laptop screen using Network Display

[ZorinNoobie]

The answer lay in me turning off my Screensaver on the HiSense Roku TV. I hope this helps anyone out there.

*vI just solved another thing about Network Display lag. I assured that I have my laptop off battery power and I disable Mouse Acceleration.
-----------------------------------------------------------------------I have Zorin OS 16 Pro. I am a noob as is my name. I attempted first and I got an error and was told I needed a Direct Display device so I bought the MiraScreen Wireless Display Dongle and set it up. I attempted several times to connect through Direct Display as it shows available but consistently gets errors. I attempt two ways through first connecting straight to my HiSense Roku TV and the next way is to the Mirascreen. Each time it gets an error.

I have no idea what is running natively as far as X11 or Wayland and I just learned about those today so I am not up in the details by much.

Excellent job on solving your connection issue with your screen, as well as the lagging issue you had.

I have a Chromecast which works good with my tablet, but I have never used a Miracast device, so I wouldn't have been much help anyways. The knowledge I have, is how to setup a Google Chromecast with a monitor/tv, and a tablet, using the APP.

As far as the lagging was concerned, power management is always getting in the way of a computers ability to produce full performance. This is the reason why I always disable it.

When it comes to notebooks, I believe in full performance, they use less power then desktops anyways, so it should never be a problem. Again, great job on doing some self solving, you are positively stellar!

Thank you. I also followed your advice about shutting down Power Management and it solved whatever lag left remaining. Now it keeps up!
