Devices differ in how they scale display windows, and some devices default to settings that cut off necessary portions of the platform display space. If parts of the display window are cut off from the visible area, or if video panels appear with slider bars, resize the display.

• For Windows computers, press and hold the [CTRL] key while tapping the [-] key. (Pressing [CTRL] with [+] will reverse the change.)
• For Mac computers, press and hold the [COMMAND] key while tapping the [-] key. (Pressing [COMMAND] with [+] will reverse the change.)

Additionally, participants may need to resize components within the platform display window. The slider bar between segments can be dragged with a pointer to change the relative display size.
