How to Distinguish Screen Resolution

WHAT IS THE SCREEN RESOLUTION?

Screen resolution is the number of pixels in each dimension that can be displayed. It is often quoted as Width x Height in pixels. For example, a screen with HD resolution (1280x720) means that for that screen there are 1280 horizontal rows and 720 vertical columns containing pixels. And then there will be about 1280×720 = 921,600 pixels that exist on the screen.

Usually, people often think simply that the larger the screen resolution, the more detailed the image displayed on it. Actually, this depends on many factors such as screen technology, pixel size or screen size .

STANDARD SCREEN RESOLUTION

1. Low resolution

The early laptops or phones had extremely poor resolutions with resolution standards such as:

- QQVGA: has a resolution of 120 x 160 pixels or 160 x 120 pixels. This resolution is used for phones with push buttons such as BQ-2412 Quattro, Nokia 230 Dual Sim, BQ-3201… With the display screen not as sharp and beautiful as other lines because of this screen resolution. very low.

- QVGA: has a resolution of about 320 x 240 pixels. This resolution is used on low-priced Feature Phones such as: MOBELL M228, Nokia 150,...

- VGA: Has a screen resolution of 640 x 480 pixels with an aspect ratio of 4:3 (width x height). In the past, the screen resolution of 640 x 480 pixels was applied as the standard resolution for devices. However, with the strong development of technology, VGA is no longer popular and widely used.

- WVGA: has a resolution of 768 x 480 pixels. WGA today is used for low-cost smartphones in the market

• 720 x 480 pixels with 3:2 . aspect ratio
• 800 x 480 pixels with 5:3 . aspect ratio

- FWVGA: resolution is 854 x 480 pixels with 16:9 aspect ratio widely applied in low-cost smartphone phones.

- SVGA: has a total of 480,000 pixels (800 x 600 pixels) with an aspect ratio of 4:3.

- DVGA: has a resolution of 960 x 640 pixels with 3:2 aspect ratio, used in the screen of iPhone 4, or iPhone 4s, ... or Samsung Galaxy J2 Prime, J2 Core or Samsung Galaxy phones. J2 Pro was released in 2018, you will encounter the qHD standard with a size of 960x540 pixels equal to ¼ of the HD standard.

2. High resolution

Today, along with the development of technology, the above-mentioned low-standard screen devices are used less and less. Instead, devices with high-quality screen standards such as HD, Full HD, 2K or 4K are increasingly used.

- HD and HD Plus: HD resolution has a width of 1280 pixels and a height of 720 pixels, with a refresh rate of 60 frames per second. The pixel density is 921,600 pixels per frame. 3 times sharper than the old VGA standard. Commonly used as the video and display standard of Samsung Corporation.

HD+ resolution is an upgrade of HD with higher resolution and extremely high pixel density.

• 1440 x 720 pixels 16:9 aspect ratio
• 1480 x 720 pixels aspect ratio 16:9
• 1520 x 720 pixels 16:9 aspect ratio

Borderless support with 18:9 and 18:5:9 aspect ratios is applicable to mid-range screens or smartphones from 2018 to present.

- Full HD and Full HD plus: have a horizontal resolution of 1920 pixels and a height of 1080 pixels and an aspect ratio of 16:9. Commonly used in video standards with a refresh rate of 60 frames per second.

Full HD screen is also used for smartphones, curved screen, overflow screen with 18:9 and 19:9 frame types and gradually replaced by Full HD Plus screen. So what is Full HD Plus?

- Full HD Plus also known as Full HD + or FHD + is an upgraded form of Full HD. The screen has a height of 1080 pixels, but it has more width as follows:

• 2,160 x 1,080 pixels
• 2,280 x 1,080 pixels
• 2,340 x 1,080 pixels

However, Full HD plus resolution is losing its trend in the market today.

- 2K and 2K+: Also known as Quad HD or QHD standard, monitors according to this standard have a resolution of 2560 x 1440 pixels. This technology helps smartphones have a sophisticated, sharp, attractive screen and make photos more realistic. With a resolution many times higher than Full HD . Some argue that the 2K standard is higher than Full HD but is quite redundant when applied to normal screens. However, in high-end smartphones when equipped with these high-tech panels and technology, users will experience an extremely sharp and attractive display screen that is much more attractive than HD resolution.

- 4K: This is the standard Ultra HD or UHD equivalent to 3840 x 2160 pixels or 4096 x 2160 pixels 4 times Full HD. The 4K standard is not yet popular with smartphones, but mainly integrated in high-end TV screens. Not stopping at 4K, nowadays, people continue to develop other standards such as 4K + (UHD +) with a resolution of 5120 x 2880 pixels and 8K standard (FUHD) 7680 x 4320 pixels.

In short: Screen resolution will greatly affect the display quality of devices. With the same screen area, the higher the resolution, the sharper and more realistic the image display will be. In addition, we should not completely deny the effect of resolution, as it is always one of the most noticeable parameters when buying equipment or working with images.
