From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Looks like there's a lot of latency
Some numbers I can give you: X11 Screen capture: ~1ms VAAPI video encoding + capturing: ~12ms NVENC video encoding + capturing: ~10ms End to end video latency over WiFi to iPad: ~50ms (Measured by taking a photo of both screens with a timer running)
Tested on a Dell XPS 15 with a screen resolution of 1920x1080.
On Android devices you can reduce the latency brought by WiFi by using USB tethering or adb, see the FAQ.
Oh neat, thanks
How's the input latency to the main screen only? It seems like it mainly lags on the tablet screen.
Yes you are right, input lag is definitely lower. I don't have numbers though as it is kinda hard to measure.
