When you want to buy a new display, then you may wonder what resolution should you buy. Now, there are 720p, 1080p, 1440p, 4K and 8K resolutions, and this post from MiniTool Solution will give you a full introduction to 1440p resolution.

What Is 1440p Resolution?

First of all, what resolution is 1440p? In fact, 1440p is the abbreviation of 2560 x 1440 resolution at a 16:9 aspect ratio. Sometimes, it is called Quad High Definition (QHD) because it provides four times the resolution of a 1280 x 720 HD display. WQHD is another descriptor for the 1440p resolution.

Note: Do not confuse WQHD with UWQHD! Ultra-Wide Quad HD actually possesses a resolution of 3440 × 1440, which is different from 1440p.

The letter p after the number indicates how the resolution is drawn on the display, indicating whether the resolution is progressive (1440p) or interlaced (1440i). The interlaced resolution is drawn on the screen in alternating frames, even number frames only show even-numbered lines and vice versa.

Switching back and forth between these can make the entire screen visible to the human eye, but it can also cause the unique “flicker” phenomenon associated with older CRT monitors. In contrast, progressive resolution draws all lines continuously, providing a higher-quality image.

Where Do You See 1440p?

In the fall of 2006, Chi Mei Optoelectronics (CMO) proclaimed that it would release a 47-inch 1440p LCD panel in the second quarter of 2007; the panel was scheduled to debut at FPD International 2008 in the form of an autostereoscopic 3D display.

You can find that the most common locations with 1440p resolution are on laptops. It is one of the most common computer gaming resolutions, and the QHD laptop is reasonably priced. Recently, gaming consoles have also entered the 1440p, with PS4 Pro and Xbox One S both adding compatibility with QHD and 4K.

1440p is also ubiquitous in mobile phones because it greatly increases the pixel density on small screens and improves the definition of small images. The Vivo Xplay 3S, released in December 2013, was the first smartphone to use a 1440p display. By 2015, 1440p had been widely adopted by large companies’ high-end flagship smartphones.

Of course, you can also easily find 1440p resolution in video sources such as cameras. Any 4K camera can also support 1440p, and you can even find a small portable 1440p source from GoPro.

1080p VS 1440p VS 4K

When you want to buy a new monitor for gaming, then you may wonder what resolution is suitable for you. There are some common gaming monitor resolutions:

  • 1920 x 1080 — FHD (Full HD) / 1080p
  • 2560 x 1440 — QHD (Quad HD) / 2K 1440p
  • 3840 x 2160 — UHD (Ultra HD) / 4K 2160p
  • 7680 × 4320 — FUHD (Full Ultra HD) / 8K 4320p

And this part will give you some information about 1080p vs 1440p vs 4K.

1080p VS 1440p

Obviously, in some cases, you can only use QHD. But what are the advantages of resolution when you choose?

First, if you convert from 1080p to 1440p, there will be a huge difference in video image quality. But whether you can notice this change or not depends on the size of your screen and the distance from the screen.

For a computer screen a few feet away from your face, you'll notice a difference if the screen is larger than 27 inches. But for TV screens viewed from a distance, unless the screen is larger than 65 inches, it is difficult to notice that moving to 1440p will be very different. But within this range, 1440p is ideal.

It is not the only important difference to make videos look good. 1440p is also useful on screens where the screen is too small to notice image quality, as it gives small images a higher degree of definition.

On cell screens, the icons become clearer, and on computer monitors, the higher-resolution give you a larger workspace. Compared to a Full HD display, it can display more on the screen and still have a clearer definition, making it ideal for video and photo editing.

Since the letters are well defined but much smaller on the screen, they can sometimes cause readability issues, but the fact is that even on smaller screens 1440p can be beneficial.

1440p/2K

4K has all the advantages of 1080p that comes with 1440p but to a greater degree. So why don’t you just simply use 2160p? The most important questions to ask are whether your computer will meet your expectations at that resolution and whether the increased price is worth it.

4K places high demands on your GPU. If you are doing something complicated, such as gaming or capturing video, you should research whether your setup is adequate. When playing games, you need to pay special attention to the impact of increasing the resolution on the frame rate.

In most cases, if your fps cannot be upgraded to 4K at all, it is best to choose QHD. If you want to capture video, 4K requires the latest Pentium i7 processor and a powerful GPU, but it takes much less time to capture 1440p.

Then, of course, you have to consider costs. It's no amazing to learn that newer and higher resolution displays are much more expensive, sometimes even twice as expensive as their 1440p counterparts. So you have to check again if the added definition is worth it.

The general consensus is that for computer monitors a few feet away from your face if the size of QHD and 4K is greater than 32 inches, you will notice the difference between them. Of course, as your GPU works hard to render 4K video, there is usually a drop in frames per second.

Bottom Line

To sum up, this post has given you a full introduction to 1440p resolution. In addition, you can know the differences 1080p, 1440p and 4K.
