→Display lag
===Display lag===
This is the lag caused by the television (which is also called "input lag" by the first definition above)digital televisions and monitors. Image processing (such as upscaling, 100 Hz, motion smoothing, edge smoothing) takes time and therefore adds some degree of input lag. It is generally considered that input lag of a television below {{nowrap|30 ms}} 30ms is not noticeable,<ref>http://www.bit-tech.net/hardware/monitors/2009/02/06/the-dark-side-of-overdrive/4</ref> discussions Discussions on gaming forums tend to agree with this value. Once the frame has been processed, the final step is the [[pixel response time]] for the pixel to display the correct colour for the new frame. [[CRT tvs]] and [[monitors]] have no input lag.
