What is qhd and hd

But if you're someone who values a crisp screen, resolution is going to be an important consideration. Here's what you should know about QHD resolution and how it compares to other resolution options on the market. Quad high definition QHD is the standard resolution for certain high-end devices like laptops, televisions, and phones. It has a display resolution x pixels — or four times that of p, hence the name — in a aspect ratio. You may also see WQHD when searching for devices that stands for "wide quad high definition.

The "W" is usually meant to signal that it has a aspect ratio , since that can be a selling point for manufacturers, despite that the aspect ratio is already a feature of QHD. QHD is also sometimes labeled as 2K or p for marketing reasons. An ultrawide QHD screen expands the horizontal pixels to and has a aspect ratio. Because of that, it's also generally better suited to larger monitors, allowing you to do things like have more windows open on your screen at once.

However, it will also eat away more of your battery life if you're using something like a mobile device, so you will have to make a judgement call there. Since early , many phone companies have started incorporating qHD into the making of the screens in their devices and gadgets. It seems to be incorrect.

Difference between qHD and HD. However, both these formats differ in their resolutions and coverage of devices. Affiliation qHD is a subtype of HD. HD is the original format. See all comments 2. Shame they got the term wrong. And majority of the market is misinformed that way as usual. HD aka p. Pixel density is often referred to as the pixels per inch or PPI number. A higher display resolution also helps games appear smoother with fewer jagged edges.

However, there is a limit on the level of detail that the human eye can see for a given viewing distance. For a small 5-inch smartphone, an FHD resolution has you covered pretty much regardless of how close you hold your device. The graph below plots roughly the maximum pixels per inch you can see for a given distance in yellow.

I calculated the PPI for these distances using the equations you can find here. The PPI offered by various resolutions for three unique display sizes is shown in the column plots. For devices between 6 and 7-inches in size, the crisper density of QHD is just about noticeable when holding phones closer than 30cm from your eyes. The key takeaway is that higher resolutions are only just noticeably better on the very largest phones held very close up. Hence why this display resolution has become increasingly popular in the past couple of years.
