Is there is simple way in Linux to start application, in Virtual screen with different resolution

This will be similar to virtualization, except it target is changing screen resolution only.

I want to start my application, e.g. web browser in different native resolution I don't mind connecting it via VNC or other remote service ,
I don't want to consume a lot of my laptop limited resources (~ 4GB of RAM).

    Just set up SSH X11 forwarding or use the $DISPLAY number of an existing VNC (for example) session in the xvfb-run command.

    You can find many examples I tried it many years ago and forgot the exact syntax. Should be easy though..
