Hey guys, just a heads up on a product recommendation: today my Lenovo stick PC arrived, and it works perfectly.
it's about the size of a Milky Way candy bar, plugs directly into the HDMI slot of the monitor, and it runs iScored no problem. Loads fast, and scrolling is quite smooth at 1080p. it's about $100, and that includes Windows 10 pre-installed. Much easier to set up than the Raspberry Pi 3, clearly a heck of a lot more powerful, and not too much more expensive (once you buy a case, power supply, and cables for the RPi3 -- all of which the Lenovo comes with).
this is the one i bought: https://www.amazon.com/gp/product/B01G729CQW/ref=oh_aui_detailpage_o01_s00
