How do I know whether the device im using to render a video, is rendering it in 4K? I’m not familiar with the nomenclature, but by device I’m talking about anything capable of generating video, such as a camera (which records video), or a ps5 (which generates a video or graphics?)
What do I need to have / do to be able to view a 4K video in the “best way” possible (im not sure how to frame this exactly – I want to watch a 4K video in 4K, perhaps?)
If im viewing this video on an external monitor, what changes?
If the monitor is 4K, does that suffice? What cabling will I need, if at all?

The quality of the video as a viewer, depends on several factors. The first, of course, is whether or not the video was recorded in 4K or higher resolution. From there, it depends how the video is encoded, whether it be on a Blu-ray, or as a video file on a computer, or on a streaming service. The next link of the chain is the hardware that is decoding the video. The hardware needs to be capable of both interpreting and rendering the video in the desired resolution. If the video player is not capable of rendering in 4K, most of them can downscale, or transcode the video to a lower resolution. Additionally, 4K video is now frequently accompanied by a feature, called high dynamic range, which encodes a wider range of colours within the video. This allows colours to be rendered more vividly and lifelike. As you mentioned, cables and monitors are critical to displaying video in this way. From your computer to the monitor, you need to have three key things: a video card or processor with embedded graphics that is capable of rendering 4K, a video cable to connect your computer to your display (typically typically HDMI or DisplayPort) that is capable of transmitting in 4K, and a display (monitor, TV, or projector) that is capable of displaying in 4K.
