Oi oi
@Waynej will have a few words as he bought one for the same purpose.
I got the Linx 1010B and have been happy with the streaming. It occasionally misses a few frames if I have the quality on Very High, seems to be running fine on High.
I have not had the issue with borders as pictured above. The only odd things I have noticed are with the W10 Xbox app's DVR capabilities - the game stream is recorded at the tablet's displayed resolution. So 1280x800 then, and this recording then displays black borders as can be seen in my video here - video was recorded at Medium btw (Not an issue if I force the tablet to 1280x720 - recording is fine then but have play with slight borders).
What I have been trying to figure out is how to record the streams at 60fps, I am sure that was mentioned previously.
I had a Micro HDMI cable delivered today and was eager to set the Linx 1010B to output to my TV at 1080p. I tried Halo TMCC collection today playing in 1080p streamed to the Tablet which was output to the TV - and it was great. Smooth as butter.
However, I did have issues with trying to record at 1080p, perhaps the Linx 1010 just doesn't have the grunt to record at 1080p... when recording the gameplay would become laggy, major delay and eventually the stream just ends.
It's perfectly fine for playing in 1080p on a TV in another room, just not recording. So mostly does what I want. Would have been chuffed to bits if recording at 1080p would work. Bro recently updated his old W7 laptop to W10 so may test streaming on that wired and wireless, and see how it compares.
