moonlight-android - opensource android application to connect to your NVIDIA gamestream functionality provided by most modern NVIDIA graphic cards
I use it often for streaming my computer from my bed to play tactic/mouse heavy games, but latency wise it's very good if using hardware encoding. Less friction than a parsec and/or steam link setup.
Additionally (though I haven't tried it) there is a server software to emulate the NVIDIA(tm) gamestream functionality for AMD/Intel/etc, giving you an open source and low friction way to setup remote game streaming and/or desktop use
