Does TV Resolution Matter?
When we're talking about TV, we're talking about one big thing. Resolution Sharper Images, Crisper Action, immaculate detail in everything from sports to documentaries to video games in just a few years. We've seen the race move from seven twenty to ten eighty P, two four K. and beyond, and this brings us to today's question. Does TV resolution matter spoiler alert? The answer is yes absolutely or maybe a better way to say it is yes, absolutely, but with a footnote before we get to all the weird stuff that footnote represents. Represents! We need to understand resolution itself. Resolution starts with the Pixel. A Pixel is the smallest possible unit of a digital image, a single point of light when you hear manufacturers top about resolution there, describing the number of pixels on a given screen, so an old school cathode Ray, TV would display the equivalent of three hundred thousand pixels on screen while an HDTV could pack more than two million pixels into a screen. The STANDARD WAY FOR TV makers to classify resolution is with numbers followed by a letter. The numbers indicate the. The rows of horizontal pixels so think four eighty, I ten eighty P, and so on the bigger the number, the more pixels on the screen, the letters at the end of the numbers stand for I is interlaced and P for Progressive Scan. The differences are important, but fairly complicated, so let's save that one for another day. Using more pixels to create an image creates a smoother, less blocking or pixelated image, so at first glance it sounds as if more pixels equal a better experience, right not so fast slick. Here's where our footnote. Footnote comes in Pixel. Density itself is not the only factor in the race toward a better sharper image. If we're looking at resolution as the ability to discern fine details, several other factors come into play for instance. What's the source of the image? What role does color play? How close or far are you from the screen? And how big is the screen for example? If you're watching a small screen, say twenty six inches from ten or more feet away. Your I won't be able to tell the difference between anything from four. Four eighty two four K., the farther you are away from the image source, the smoother the picture appears as for the size of the screen. Well sure you could have a twenty six inch TV with ten eighty line resolution, and it would still have the same number of pixels as a fifty five inch, TV with otherwise identical specs, but the pixels would be physically smaller so in this context size definitely matters if you put a twenty six inch HDTV with seven twenty line resolution next to another twenty six inch HDTV with ten. Ten Eighty, you may not be able to tell the difference between the two. These are just a few of the pertinent factors in the overall equation. There's another big question here to does the human I have a resolution limit. How many individual pixels can the human I perceive? And that's a tricky question to our eyes are not cameras, instead their an initial step to an intricate process, involving loads of unconscious estimation and guesswork in our brains. It is true that after a certain point, the human eye is unable to differentiate or Or appreciate the differences between some Pixel densities with the right source material equipment and viewing distance four K. really can make a difference for example if you're sitting a few feet from a sixty inch four K. television with an ultra high definition video feed, you'll be able to tell if it suddenly switches to regular hd or brace yourself standard definition, the limits of HDTV a failure of technology. There are limit of our biology, if we can't tell the difference between a lower resolution, twenty six inch TV in an HD version then. Then! There's not much incentive to buy the latest ultra high definition TV set, but this isn't the end of the story. The race for higher resolution continues cameras that shooting four K. have already become the norm and each year bring new innovations. These ultra high definition technologies may not make for a better picture on a home television, but in a movie theater it makes a big difference in the future. We might not care as much about resolution. It's possible that other technologies like high dynamic range may become the next big thing.
