Hello, @meepytinity

The ExecStart command starts VNC and sets the color depth to 24-bit color with a resolution of 1280x800. You can modify these startup options as well to meet your needs.

In the following line;

ExecStart=/usr/bin/vncserver -depth 24 -geometry 1280x800 :%i

Have you checked that in the /etc/systemd/system/vncserver@.service file.

Let me know how it goes.
