Btw, the reason you’re not seeing games in 4K is that you don’t have the right equipment. There are only 2 specific boxes from Comcast that broadcast 4K and they are only available to x1 subscribers and not available in all areas.
The other reason is that a lot of tv shows aren’t broadcast in 4K because believe it or not the world isn’t ready for it. You still have homes that are barely set up for digital let alone high def and 4K (meaning not current TVs that can even display it), so there isn’t as much of a demand as you think. the average home has less than 4K tv and a dated set top box that can’t even display 4K so for that reason you aren’t getting games and shows in 4k. Most tv shows aren’t recorded in 4K as well so the source isn’t even up to date. Most 4K content you will find through Netflix, prime, YouTube tv, etc.
if you have a 4K tv, you will notice the difference if the source is 4K and the equipment can display it in true 4K (without upscaling). If you have a smart tv, go watch a 4K Netflix show via the tv app, and then go watch that same show via the Comcast box Netflix app. You’ll see the difference immediately.
And refresh rate has nothing to do with resolution. Refresh rate is how smooth it will look and lag time which is more important in heavy gaming and fast action sports like hockey or Bball. In fact a fast refresh rate watching those sports can make you sick, it’s really hard to digest. It creates the soap opera effect.
On a side note if you have 4K and a ps4, get the game called horizon zero dawn and tell me you don’t believe in the power of 4k.
I think our comp sci major needs to spend more time in the books. 😆
