To change the size of the Spectrum screen border
On the View menu, highlight Border.
Click one of:
Small, for a tiny border - suitable for lower resolution displays or slower computers.
Medium, for about two thirds of the size of the real border.
Large, for the entire border.
Note
Larger borders require more computing resources. On slower computers you should choose Medium or Small.
If your Windows desktop is not big enough to accommodate the Large border, the option will be greyed out.
The border is always visible in full screen mode.
