Why can't every single video be 4K? I don't know why. But I really want every single YouTube video like I mean every single one. Every video From when YouTube started. To now Like videos that are a decade old. Are 360p or 480p. WHY CANT THEY BE 4K. It really ruins it when you try to watch a 10 year old video on a 4K TV. Because it's a 4K tv. Why wouldn't be 4K.
