The short and simple answer to the age old question “does HDMI cable cause lag” is a big no. This is a myth that has been busted time and again. HDMI cables do not cause any lags. The input lags you experience are mostly caused by the TV, monitor or the projector itself.
Does length of HDMI cable affect performance?
Does HDMI length matter for gaming?
Anyone encounter issues with too long of HDMI when gaming? Yes. Standard cables are passive and long lengths degrade signal. While you should not have issues with 25ft (max theoretical limit is at around 50ft) if you want to go long you need an active (powered cable) or a converter box from hdmi to fiber/cat.
How long can HDMI cable be before latency?
Like many audio, video, and data cables, HDMI cords can suffer from signal degradation at longer lengths—50 feet is generally considered the maximum reliable length. And it’s rare to see an HDMI cable longer than 25 feet in a store.
What happens if HDMI is too long?
Since HDMI is a fully digital signal, there is no way to signal to be of lesser quality than any other cable. The only thing that happens is signal drop-off when sending high bandwidth signals over a too-long cable or a cable that isn’t rated for the specific HDMI standard.
