Hi,

I got my MI BOX S several month ago. It's been working fine except it keeps flickering on my Hisense 4K TV when playing video. It's weird because:

• Only flickering when playing SDR video with " Hardware decoding ". Unfortunately most stream service are default to that. HDR video is working fine.
• " Software decoding" works fine.
• UI interfaces works fine.
• Never flickering on my 1080p Asus monitor or RCA TV with any setting.
• At the same time, Roku is working fine on my Hisense TV without flickering.

These solution did not work:

• Change cable.
• Dynamic brightness on/off.
• Dynamic contrast on/off.
• HDMI color range auto/full/limit.
• Output format: Ycbcr 420 444 / RGB / 8 bit 10bit.
• HDMI 2.0 mode: standard/enhanced.

However I do find some workaround I wanna share it here:

• Enable SDR-HDR feature: Since it only flickering on SDR video, force it to HDR mode seems a good solution. However it has a tradeoff, the video color shift a bit with SDR-HDR.
• Reduce resolution to 1080p or lower: It did reduce the frequency of flickering, however it still flickering.
• Tune the " color" setting slide bar on the TV: simply tune the value of " color " up and down stop the flickering completely. But it's not permanent, once reboot the TV or MI BOX the flickering comes back.

Any idea?
