Hi, first problem:

I have a Mi Box S with latest firmware on a Samsung tv 4k of 2019. I noticed some stuttering when i see something on Netflix, particularly 4k hdr videos. It happens every 15 seconds. I already reset tv and mi box, chenge hdmi cable and hdmi port on tv. The second problem with Mi Box S is that after it goes in stand by, the colours on tv turns more faded, then when i change the settings ybrc from 420 to 444 they returns vivid. Why is this happen? The first problem is really annoying in fact i have to ure netflix app directly from tv.

​

With the mi stick tv i have other type of problem, for example in certain point like home page on youtube app, when there are many white writings, they sparkling or flickering i don't known the correct term. If i record it, on video doesn't shown nothing. I don't known if is a problem form tv or mi stick...
