It's interesting to see how interlaced video works and I've known about this for decades. This Computerphile video explains the problems that come with displaying it deinterlaced on a progressive scan monitor, which is all CRT, LCD and OLED monitors. Also note that most, if not all, LCD and OLED monitors can actually display interlaced video directly and I've played around with it a few times.
Looking at the Windows desktop in interlaced format on my LCD monitor is pretty hard on the eyes with all the line twittering and flickering, and when the mouse or a window is moved, its breakup while it moves due to the jumpiness of the typical mouse pointer motion. It's especially tough due to the absolute sharpness of the picture, which allows interlaced artifacts to be at their most noticeable. Looks fascinating though, a bit of a nerds' paradise lol. To access the interlaced modes, you may have to use the HDMI port on your graphics card and monitor or the driver's control panel won't offer them.
The thing to realise is that since a progressive scan is a full superset of an interlaced scan, an interlaced picture can be fully and accurately displayed on a monitor receiving a progressive signal, complete with all its glorious line twitter artifacts and flickering! The interlaced scan just needs to be formatted for display using black frame insertion for the "missing" fields and mapped to the progressive scan when using the progressive signal, or interlaced on progressive if you like. Would have been nice if they'd explained that in the video.
In fact, I've actually seen it a few times on Sky with their graphics during sports programs, with the line twitter very visible even though the Sky Q box is outputting a 4k60p signal. It's not very often though and tends to happen when they advertise boxing or something. I wonder how many other people seeing that understand what's happening. I'll bet next to none.
Finally, a fun fact: this video was released in August 2016 so note the political references of the time. How things change.
