Resolution is a measurement of the count of pixels in a display or screen of any device, it determines the clarity of the screen. High-resolution displays give a vivid experience, no matter which device you use, such as Android, iOS, PC, TV, or Tablet. But having only a high-resolution display does not assure high-quality projection, it is also determined by the quality of your content. So if you have a high-resolution content source, you must be looking for a display that is on par with it. This article will help you by explaining what is difference between 4K, QHD, and UHD resolution.
The primary difference in these three formats is that 4k has a horizontal pixel count of approximately 4000, QHD which is Quad HD has 2560 x 1440 pixels which allows it to be of 16:9 ratio, and UHD also known as Ultra HD has a pixel count of 3840 x 2160.
It has approximately 4000 pixels horizontally and 2000 pixels vertically which make it roughly 8 million pixels. To explain it simply, around four Full HD displays make one 4K.
This resolution has been used for more than a decade, but it got popular nowadays cause TVs and other electronic devices have started selling products that are claimed to be 4K at a cheaper price than in the past.
And since the majority of contents are still not on par with this resolution, many 4K TVs provide UHD upscaling that doubles the pixel horizontally and vertically of the full HD content to match the resolution.
Quad High Definition has 2560 pixels horizontally and 1440 pixels vertically which make it roughly 3.69 Megapixels. Four HD screens will make one QHD, quad itself means four. It is mostly found on smartphones and is called 2K as it is roughly half of 4K.
UHD or Ultra High Definition has 3840 pixels horizontally and 2160 pixels vertically which make it roughly 8.3 million pixels. It mostly gets confused with 4K and in today’s time, it has been mixed up by Television companies too. As you might have seen 4K UHD TV in a showroom. 4K was previously used in production and UHD was used for devices like TV. To simply put it 4K TVs are mostly just UHD but because of their near pixel counts, they are treated as one in a commercial market.
This is all you need to know about 4K, QHD, and UHD resolutions and how they are different from each other. In the meanwhile, you can also check out our other article: Best Portable And Handheld TVs, and LED vs. OLED: Which is the Best TV.
