My Mi Box will frequently swtich from 4k @ 60hz to 420p when it wakes up from sleep. When I go into display settings only 3 resolutions are available (480p, 720p, 1080p) I have to do a reboot of the box to bring back all the other resolutions including 4k. This seems to be happening post oreo.
Anyone else facing similar issues?
Edit: so a working solution I found, not optimal but I enabled developer options and enabled the option to always keep the mi box awake. I also had to disable HDMI CEC on the MI Box otherwise my TV remote would sleep the mi box along with shutting off the speakers. Ideally I would like full HDMI CEC but no biggy, the MI Box just stays on all the time.
Yep, I disabled auto resolution and manually set it. No problems after that.
