Fun Fact: The original Splatoon can be played on a CRT TV with no special adapters required! The Wii U natively supports the Wii's AV Multi-Out cables, allowing for it to connect directly to a CRT TV like the one in the video. The picture is letterboxed because this CRT TV has a 4:3 aspect ratio, though 16:9 aspect ratio CRT TVs do exist.

Playing Splatoon 1 this way is pretty fun, though it is a bit blurry and I would definitely prefer to play on my OLED TV instead. Regardless, I do appreciate that this is the same TV I used to play my N64 on back before I even had an HDTV!
