Settings to improve the quality of the desktop display while showing it

Good day,
I installed the jitsi-meet in the local network but there is a need to improve the quality of the desktop display.
Tell me where to make changes to the settings.
Thank you.

What do you mean exactly?

Hi, @saghul Thanks so much for responding.
Most often, when “Show Desktop” is turned on, the quality of the video rises to HD, and is equal at the current desktop resolution. But sometimes, for some unknown reason, when you enable “Show Desktop” the quality becomes SD. In this case, the text on the screen is blurry and difficult to read.
Is it possible to prevent Jitsi from changing the Desktop resolution and varying the quality at the expense of frames per seconds?
