As a result of the fact that an HDMI splitter is like a new link in the visual signal chain, it will introduce some additional delay; however, with a powered device, this delay is not any more than a few milliseconds (ms). A delay of 2 milliseconds is hardly a cause for concern.
Does HDMI switch affect input lag?
The Input Lag usually comes from the need to convert signals – a HDMI Switch itself does not introduce Input Lag, since it has no need to convert any signal, it simply channels it through a different port. a difference in latency over the latency a normal cable would add is basically non existant.
Is there input lag with HDMI Splitter?
there will be no input lag and it cannot reduce the quality.
How do I reduce input lag?
First, try limiting the frame rate to just under your display’s refresh rate. Attempt a higher frame rate. Second, try pushing the game to a much higher frame rate—double the monitor’s refresh rate or more. This should lead to a small but noticeable improvement in input lag.
