Examples of screen magnifiers include ZoomText, MAGic, and SuperNova.
Screen magnifiers can support both character-based terminals and X-Window-based VNC.
If you are using the screen reader function of the screen magnifier (ZoomText screen reader), then you should use a character-based terminal as described above.
If you are using a VNC, decide your preference for a window display, for example, TWM or ICE. A display setting for ICE can be done with the following:
vncserver -geometry 1600x950 :2
1600x950specifies the display size, and
:2specifies the VNC display number.
