These 3 letters are why you should upgrade your Blu-ray discs to 4K UHD

Plenty of people have been collecting physical media for decades, and if you fall into that group, then you’ve probably upgraded your favorite movies from format to format. Titanic is one of my favorite movies, and I have it on VHS, DVD, Blu-ray, and 4K Blu-ray. If there’s something that comes out after 4K Blu-ray, I’ll probably get the upgrade there as well.
