Can't believe no one pointed it out:

> Meanwhile, there’s another output on the splitter (that can either be 4K or 2K (some people quaintly call this “1080p”))

Nope. 1080 is the horizontal resolution as is 4K. So 1080p is not 2K. 1080p is 2 MP, and 4K is 8MP.

4K is 2160p, exactly double 1080p in the vertical. In the horizontal, it’s 1920 for 1080p vs 3840 for 2160p (colloquially known as 4K). The industry naming convention is not consistent.

Your both wrong, conflating standards from the world of cinema and broadcast.

4k (a cinema format): 4096x2160

2k (a cinema format): 2048x1080

UHD (a broadcast format): 3840x2160

HD (a broadcast format): 1920x1080

UHD also includes 7680x4320 *HD also includes 1280x720

You are wrong; look it up.
