#190299 - Modulation frequency
Responding to: Dave Allan's previous message
Most IR links that I know of are modulated at 38kHz to reject ambient light. 38kHz was chosen for historical reasons, and at the time it was optically quiet. Unfortunately a number of monitors now run with a line scan frequency in this region. Does it make any difference if you change your monitor resolution or frame rate?
