I tried AMD link streaming with R290 and Xiaomi Mi Box 3, frame drops were too much and latency was too high to play.
I placed an Android phone right next to Mi box and the phone streamed the desktop just fine, there were no drops and latency was low and that was at the highest quality settings.
So obviously this is a problem with the Xiaomi Mi box 3. Which Android TV box did have the best experience with?
Probably the shield due to its power.
Probably the Shield. But if you wait a few weeks, Nvidia will release a version with a revised SoC.
Go for the Shield TV, It's like the Nintendo Switch
It is possible there will be a new shield with a updated SOC soon.
I find that it's a lot more reliable to stream at 720p with cheaper boxes. Basically lower bitrate, maybe 5-10mbps. It's not shite, playable, but you'll see lots of artifacting
There was a new version released a week ago; have you tried that?
Most likely the Nvidia Shield TV
