Lucky for us, we don't have to do any of the hard math on our own.
You can see how it scales here at each common resolution. The screen size, at a 4K resolution, calculates out to a certain number of ppi, in essence the pixel density of the screen. Whether you can make out the difference in resolution on a 4K panel versus, say, a 1440p one (that's 2,560 by 1,440 pixels) depends on your eyesight, that viewing distance, and the screen size. The tricky bit is that viewing distance isn't fixed it depends on the size and layout of your desk, your chair position, and so on. The same issues apply to monitors, just across a larger viewing distance than inches from your eyes. When something's that close to your eyes, you can more clearly see the difference. In the case of VR headsets, it makes the image look as though it's being seen through mesh, and it's why VR headsets have seen resolution upticks in successive models. In essence, the lower the maximum resolution that a screen is capable of displaying, and the closer you sit to the screen, the easier it is to see its individual pixels. If you get really serious about that question in the monitor world, it comes down to algebra, and it raises issues like pixel pitch, pixels per inch (ppi), and "angular resolutions." Let's keep it simple, though.Ī good example of the pixel-pitch problem arises in VR headsets, with an issue known as the "screen door" effect. It's not quite as simple with 4K monitors. With TVs, the answer to whether or not you should opt for a 4K model today is almost always "yes," because we sit much closer to our monitors than we do our TVs. If one of those scenarios fits your needs, though, the next step is to figure out whether or not a 4K monitor is right for you for different reasons: your desk configuration, and your eyesight. (See our picks for the best TVs, now uniformly 4K models.) That's because many 4K TVs aren't beholden to the same standards that 4K monitors are, such as the need for boosted refresh rates (for gaming models), high-level or specialized color accuracy (for content-creative ones), or low levels of input lag.

Similarly, if you want a 4K monitor solely for entertainment purposes that don't center on PC gaming, a 4K TV would likely be a cheaper option. (Of course, you may need the 4K resolution for things other than gaming, and you can always turn down the resolution when you switch to gaming.) If you don't have one, gaming at 4K is going to demand compromises-and it may not be worth the splurge. These elite cards are Nvidia's GeForce RTX 3080, GeForce RTX 3090, GeForce RTX 2080, as well as the AMD's Radeon RX 68 series-all of them expensive video cards with prices greatly inflated here in 2021. (If you're turning down the detail settings in a game to make it run better in 4K, that defeats much of the point of 4K in the first place.) And you'd want to crank everything up to make the 4K investment worthwhile. Right now, only a handful of graphics cards can reliably power a 4K screen with leading-edge, AAA game titles at top settings.
While gorgeous to look at, gaming in 4K with modern games requires loads of graphics horsepower to get above 60 frames per second (fps), today's generally acknowledged minimum for serious gamers.
All these panels remain a premium choice, but they are becoming increasingly common on desks at work, at home, or in gamers' frag dens.īut before we get too deep into the topic, we should first help you answer a key question: Is a 4K monitor right for you in the first place? Depending on what you do most with your monitor, and where you'll place it, the extra money you'd pay versus a lower-resolution display may not be necessary.įor starters, let's take gaming. Some other resolutions with approximately 4,000 horizontal pixels-most commonly 4,096 by 2,160-are also considered 4K. That's four times as many as a 1,920-by-1,080-pixel monitor-and that's a lot of pixels.
The vast majority of 4K monitors are displays with a native resolution of 3,840 pixels across by 2,160 pixels on the vertical. First Off: Do You Even Need a 4K Monitor?
