What is input lag and how does it affect projector performance?
Input lag refers to the delay between the time a signal is sent to a projector and the time it is displayed on the screen. This delay can be caused by a variety of factors, including the projector’s processing time, the type of input signal, and the quality of the connection. Input lag can have a significant impact on the overall performance of a projector, particularly in applications where real-time video or gaming is involved.
In general, input lag is measured in milliseconds (ms), with lower numbers indicating less delay. For example, a projector with an input lag of 10ms will display the image 10ms after it is received, while a projector with an input lag of 50ms will display the image 50ms after it is received. This delay can be noticeable, especially in fast-paced video or gaming applications, and can affect the overall viewing experience.
What are the main causes of input lag on projectors?
There are several main causes of input lag on projectors, including the projector’s processing time, the type of input signal, and the quality of the connection.
