The text discusses 4K resolution, which refers to the number of pixels on a screen, with 4K specifically being 3840 x 2160 px, providing more picture detail than lower resolutions like 1080p. However, for video conferencing and screen sharing in an office setting, 4K does not offer noticeable benefits as most content is compressed for streaming over office networks, and people typically don't sit close enough to notice the difference on a TV. Instead, 4K is great if you're using a video source that can send a 4K signal to your TV, such as from video streaming services or cable companies. Additionally, prices of 4K TVs have decreased over time, making them more affordable for those in the market for a new TV.
