I have purchased a usb c to hdmi connector and shows 2k very well, no stuttering. But if i go 4k, after a few seconds the buffering icon shows on the tv and then it carries on for 20 seconds and repeats the same process. My smart tv has youtube and it displays the 4k with no problems and i have changed the hdmi cable to a larger, better quality cable.

Any ideas to improve the situation ?
Many thanks.
