4K vs. How are QHD different? Terms like HD, FHD, QHD, 4K and 8K are used a lot nowadays. And if you're not an expert, knowing what they mean and whether or not there are unique benefits is sometimes difficult.
Two of the higher level resolutions are QHD and 4K. Many smartphones, TVs, and computer monitors use them. But how are these two resolutions different? Let's take a look and help you solve the QHD vs. 4K.
- 6 solutions for when the TV won't turn on
Also known as "Quad High Definition", a QHD screen is 2560x1440 pixels. This is four times higher than a standard High Definition (HD) TV or monitor, which is 1280 × 760 pixels.
When it comes to QHD resolution, a screen will have 3.686.400 pixels on it. This is a density of approximately 489,5 pixels per square inch on a six-inch screen. QHD is the standard resolution for flagship smartphone screens released nowadays.
A Full HD (1920 × 1080 pixels) display would have a pixel density of around 367 pixels per square inch. Meanwhile, the density of a standard HD screen is around 244 pixels per square inch.
Larger displays, such as monitors and TVs, have a lower pixel density. A 24-inch QHD computer monitor will have a pixel density of approximately 122,3 pixels per square inch.
For this reason, it's not the most popular choice among gamers who sit very close to their monitors. The added screen size can lead the viewer to see pixels in the content.
4K is called 2160p. It is also often referred to as ultra high definition (UHD), but there is actually a difference between 4K and UHD. A 4K display will be 3.840 × 2.160 pixels, for a total of over 8,2 million pixels. On a six-inch display, this would be 734 inches per square inch.
On monitors, a standard 4-inch 24K gaming monitor will have around 183,6 pixels per square inch.
Technically, the name “4K” is inaccurate. The "K" in 4K stands for how many thousands of pixels there are in length. QHD is called 2K because it is more than 2.000 pixels in length. However, 4K is 3.840 pixels when it comes to this.
4K is much more popular in the TV market than on smartphones. The first smartphone with a 4K display was the 5 Sony Z2015 Premium. But the resolution added at the end added little to the overall user experience.
While 4K packs more pixels into every square inch of screen, it's not as dry as most people might think. There are other things that need to be taken into consideration, they are described below.
When you zoom in on the content on the screen, 4K appears in the foreground. The added resolution is useful if you are looking to review content such as videos or photos.
When it comes to what these resolutions look like from afar, there is no real discernible difference between them. Viewing a QHD display in a busy living room or bar eliminates the need to add pixels. Because of this, the QHD can earn some points over 4K.
It's also worth mentioning that 4K consumes more power than QHD. The extra pixels consume more power than most people think. If, from a distance, there is no way to tell the difference between resolutions, it is more energy efficient to purchase a QHD display.
When it comes to spotting the differences between 4K and QHD, it's hard to stay on one side. In the grand scheme of things, you can't go wrong with either. If you want to closely examine the content you are consuming, 4K is the way to go.
If you want to save money, while still seeing a nice display, then QHD is for you. Either way, you'll still have a great viewing experience.
