A:AnswerThe PS4 Slim does not have 4K, it only does 1080p for all types of content and has HDR for games. The PS4 Pro will give you 4K Upscaling for games, 4K Upscaling for Blu Rays, 4K Streaming and HDR for all content that supports it.
A:AnswerYou can skip through the setup process if you don't want to go online. However, most games need internet to download and begin the update process so without internet it might give you some compatibility issues for some games.
A:AnswerThis is a great stand alone device with numerous functions. It has the ability to use Hulu, Netflix, Amazon, and more. If you want the ability to play games, and stream content, this will get the job done. However, I am NOT sure if you need a PS Plus subscription to steam. The reason is, we bought the service with our console and applied it first before trying Netflix. There is PS Vue which is a TV service of sorts, but I have not done the trial or subscribed. From what I heard, it does provide a fair amount of TV service.
A:AnswerThis uses HDMI only so any contemporary tv will work with that single HDMI for sound and pic. I have an iMac and to my knowledge you can't use the monitor for outside units such as gaming systems.
