Common "2x1" Misconception 

Many products listed as "Splitter 2x1" are actually Bi-directional switches. 

• As a Switcher (2x1): 2 sources, 1 screen (switch between them).
• As a Splitter (1x2): 1 source, 2 screens (only one screen can be active at a time in many bi-directional models, though true 1x2 splitters allow both)
