Hi Alenk,
as a converter, many peripherals and devices are connected it,
and at least 2 cables are involved to make sure it can work properly,
sometimes the game console(e.g. PS4) will have some issue of its own,
so we do have to check things one by one,
not all issues are caused by our converters.
we will definitely look into this that you reported,
but for now, please follow the above tips.
