Yeah, that's much better.
I'm watching on a 27 inch monitor. At that size, 480p just looks like a bunch of small colored squares swirling around.
If someone watched on a 5" phone, it would probably look OK.
The bigger the monitor, the more each pixel must be magnified to fill the screen, so you need more pixels to keep the quality up.
In my opinion, 720p still looks good up to about 50", but 1080p or up looks even better.
On a 60" TV, 720p would be hard to watch.
Like putting a size 9 sock on my size 13 foot. It might fit, but I'd just stretch it all outta shape!
