No, TV makers, 4K and UHD are not the same thing

TL;DR do not look for fancy names like "4k" and "UHD", just check the tech specs by yourself.

Spotted a mistake: when explaining that "4k" designates a resolution of 4096×2160, they incorrectly label 4096 as the "vertical resolution".

Thanks for sharing. Even i believed they were the same. Now i know where to put my money.
