I'm trying to use my sansung galaxy tab s9+ as a second monitor for my Linux PC. The PC sees the tablet, but when I try to connect, I get a log entry saying the codec is not supported. If I try to connect the laptop to my Samsung TV, everything works fine. Reading the description of the feature it says it only works with windows computers, so this raises a couple questions:
1. Is Samsung using a proprietary protocol instead of an industry standard? I'm assuming the answer to this is yes.
2. If Samsung clearly possesses the technology to use a standard screen sharing protocol like Miracast (I'm assuming something similar is being used for the TV), why create a proprietary protocol that makes this feature unusable for a majority of potential buyers?
3. If Samsung is using a proprietary protocol for this feature, is it a closed protocol, or is there an API available somewhere so a motivated developer can create a codec that can be used by something other than Windows?
I use Linux mostly for work, and I have recently dropped windows in favour of mac for all the things I can't do in Linux for many reasons I won't detail in thisnpost, but I've been a loyal Samsung customer since the Samsung galaxy S1 phone until today, having owned numerous phones, tablets, watches and TV's. The second screen feature was one of the reasons why I upgraded my tablet, and it's really sad I don't seem to be able tonuse it.
Any advice would be welcome. I have tried some of the apps that offer this capability, but none of them seems as convenient as the built in feature. I have looked into Duet, Weylus, Deskscreen, and still looking into other options, but many of them are also windows only.
