What is the optimal viewing distance to notice the difference between 1080p, 2K, and 4K resolutions

The optimal viewing distance to notice the difference between 1080p, 2K, and 4K resolutions depends on the size of the TV and the viewer's seating position. Generally, the closer you sit to the TV, the more noticeable the difference between the resolutions will be.

For a 65-inch TV, the viewing distance at which the eye can process the details of 4K content is about 4 feet. However, any distance between 4 and 85 feet will be enough to appreciate the difference between 4K and 1080p. If you sit too far away, the image will look identical to 1080p HD.

Assuming a one-hour video, a 4K video would require around 20-22 GB of storage, while a 1080p video would need around 12-14 GB of space. In terms of storage efficiency, 1080p wins this round.

The human eye can only pick up a depth and contrast difference if sitting around 5 feet away from a 80-inch screen. However, for most people, sitting 65 feet away from a 50-inch plasma TV is more practical. At this distance, the benefits of 1080p vs 720p become apparent.

For a 4K monitor, once you get above a 20-inch screen, you should start to see a difference. The recommended viewing distances for 1080p and 4K TVs vary depending on the screen size. The bigger your TV is and the closer you sit to it, the more likely you'll be able to tell the difference between standard definition, 720p, 1080p, and 4K.

In summary, to notice the difference between 1080p, 2K, and 4K resolutions, it's important to sit close enough to the TV, with the optimal viewing distance being around 4 feet for a 65-inch TV. However, the exact viewing distance will depend on the size of the TV and personal preference.
