'Don't Buy an 8K TV'

Anyone paying attention to the news coming out of CES this week has probably noticed that 8K TVs seem to be the next big thing. The science says your mortal eyes can barely tell the difference between 4K, however. From a report: Samsung announced one that's almost bezel-less. LG boasted a total of eight new 8K TVs. Meanwhile, there are two dueling standards bodies debating exactly how to define 8K. Given all this, you'd be forgiven if you thought 8K is the new high water mark for premium home entertainment and that your perfectly fine 4K panel is now no longer perfectly fine. Don't worry, it is. The coverage of 8K has really irked me. Nearly every article I've read that covers these newly announced 8K TVs seem to center around one criticism of the 8K trend: that no native content exists. This, while true, misses the point. Even if we had a surplus of available 8K content -- as we do 4K content from services like Disney+ and Netflix -- it wouldn't make that much of a difference. Why? Because whatever benefits might come from 8K probably aren't worth the added costs of getting it in the first place. Without getting too bogged down in the science, let's touch on how the human eye sees detail. We have cells in our eyes called cones that are less sensitive to light but more sensitive to detail and color. Each of your eyes has about six to seven million cones that mostly provide data on the center of your vision, or focal point. Guessing the "resolution" of the human eye is complicated, but Roger N. Clark, an expert in digital imaging, has calculated the approximate resolution of the human field of view to be around 576 megapixels, or nearly 72 times the resolution of 4K. However, that's not the whole story. In Clark's view, the biggest factor that helps TVs make a more accurate image isn't necessarily their resolution, but their dynamic range capability, or the ability of current 4K HDR TVs to display greater contrast in the dark and bright parts of an image.
