I need to access a remote machine via a high latency, slow connection. It uses x11vnc and I want it to broadcast video in much lower quality than what's actually on the screen. First thing that comes to mind is to use less colours (e.g. 8 bit), but it can be anything, as long as the remote machine is responsive even though it may, for example, show a large rich-colour desktop image (which I don't need to see anyway). Something like this, except for x11vnc.

I will, however, appreciate keeping all the text sharp because, I work with the terminal.

Here's what I tried:

I'm using the built-in Screen Sharing app, which seems to be almost the only option on Mac OS.

I'm out of ideas. Please help.

As for Mac alernatives, try VNC Viewer or UltraVNC.

Both are good, fast and configurable.
