Since QVGA is 320 pixels wide and 240 pixels high (aspect ratio of 4:3), the resolution of a WQVGA screen might be 360 × 240 (3:2 aspect ratio), 384 × 240 (16:10 aspect ratio), 400 × 240 (5:3 – such as the Nintendo 3DS screen), 426 × 240, 428 × 240 (≈16:9 ratio) or 432 × 240 (18:10 aspect ratio). As with WVGA, exact ratios of n:9 are difficult because of the way VGA controllers internally deal with pixels. For instance, when using graphical combinatorial operations on pixels, VGA controllers will use 1 bit per pixel. Since bits cannot be accessed individually but by chunks of 16 or an even higher power of 2, this limits the horizontal resolution to a 16-pixel granularity, i.e., the horizontal resolution must be divisible by 16. In the case of the 16:9 ratio, with 240 pixels high, the horizontal resolution should be 240 / 9 × 16 = 426. 6 (426 2⁄ 3), the closest multiple of 16 is 432. Brian, Matt (20 May 2013).

This resolution has an aspect ratio of 256:135 (1.8 962:1), and 8,847,360 total pixels. [68] This is the native resolution for DCI 4K digital projectors and displays. SXGA is the most common native resolution of 17-inch and 19-inch LCD monitors. An LCD monitor with SXGA native resolution will typically have a physical 5:4 aspect ratio, preserving a 1:1 pixel aspect ratio.

WUXGA [28] [31] stands for Widescreen Ultra Extended Graphics Array and is a display resolution of 1920 × 1200 pixels (2,304,000 pixels) with a 16:10 screen aspect ratio. It is a wide version of UXGA. By some producers it is called FHD+ because it is the next bigger resolution in vertical direction after FHD ( 1920 × 1080). [45] WUXGA/FHD+ can be used for viewing high-definition television (HDTV) content, which uses a 16:9 aspect ratio and a 1280 × 720 (720p) or 1920 × 1080 (1080i or 1080p) resolution. The HD resolution of 1280 × 720 pixels stems from high-definition television (HDTV), where it originally used 50 or 60 frames per second. With its 16:9 aspect ratio, it is exactly 2 times the width and 1 1 / 2 times the height of 4:3 VGA ( 640 × 480), which shares its aspect ratio and 480 line count with NTSC. HD, therefore, has exactly 3 times as many pixels as VGA, i.e. almost 1 megapixel. The graphics display resolution is influenced by the aspect ratio, which is the ratio of the width to the height of the display. The aspect ratio determines how the image is scaled and stretched to fit the screen. The most common aspect ratios for graphics displays are 4:3, 16:10 (equal to 8/5), 16:9, and 21:9 (equal to 7/3). The aspect ratio also affects the field of view and the perceived size of objects on the screen. [3] Some graphics displays support multiple resolutions and aspect ratios, which can be changed by the user or by the software.

A flat panel TFT screen, including one designed for 1280 × 1024, will show stretching distortion when set to display any resolution other than its native one, as the image needs to be interpolated to fit in the fixed grid display. Some TFT displays do not allow a user to disable this, and will prevent the upper and lower portions of the screen from being used forcing a " letterbox" format when set to a 4:3 ratio. [ citation needed] Quarter-QVGA ( QQVGA or qqVGA) [ citation needed] denotes a resolution of 160 × 120 (4:3 storage aspect ratio) or 120 × 160 pixels, usually used in displays of handheld devices. The term Quarter-QVGA signifies a resolution of one fourth the number of pixels in a QVGA display (half the number of vertical and half the number of horizontal pixels) which itself has one fourth the number of pixels in a VGA display. There are also devices with QQVGA 160 × 128 (5:4 storage aspect ratio). [131] [ failed verification]

The favored aspect ratio of mass-market display industry products has changed gradually from 4:3, then to 16:10, then to 16:9, and has now changed to 18:9 for smartphones. [65] [ needs update] The 4:3 aspect ratio generally reflects older products, especially the era of the cathode ray tube (CRT). The 16:10 aspect ratio had its largest use in the 1995–2010 period, and the 16:9 aspect ratio tends to reflect post-2010 mass-market computer monitor, laptop, and entertainment products displays. On CRTs, there was often a difference between the aspect ratio of the computer resolution and the aspect ratio of the display causing non-square pixels (e.g. 320 × 200 or 1280 × 1024 on a 4:3 display).
