"Is it beneficial to set YouTube to 4K resolution on a 1080P monitor for PC viewing?"

4K videos on YouTube have a significantly higher bitrate, resulting in far less compression artifacts on a 1080p monitor.

The primary drawback of setting YouTube to 4K on a 1080p monitor is that it consumes more network bandwidth and computational power from your computer.

YouTube's 4K uploads can vary in quality, leading to inconsistencies in picture and detail.

1080p displays can only display 1920x1080 pixels, while 4K displays can display 3840x2160 pixels, which is roughly four times as many pixels.

When watching 4K videos on a 1080p monitor, the 4K video gets resized to fit the 1080p resolution.

YouTube uses a lossy compression algorithm, which means the videos are far from perfect quality at the resolution they are stated at.

The bandwidth a video feed is given does scale with resolution, meaning 4K video streams have higher bandwidth requirements than 1080p video streams.

For TVs going to 4K from 1080p is worth it only if you'll be watching native 4K content while sitting at a close enough distance to notice the extra pixels.

For PC monitors, it depends on whether you'll be using the monitor for content creation, gaming, or general use to determine if setting YouTube to 4K is worth it.

The common names of the resolutions don't all relate to the same thing, as 4K actually has more horizontal pixels than vertical pixels.

1080p monitors can only display up to 1920x1080 pixels, while 4K can display up to 3840x2160 pixels.

You can get 4K resolution on any 1080p monitor provided you have a 700 series or above NVIDIA graphics card.
