Difference Between HVGA and WQVGA

Display screen resolutions refer to a wide variety of pixels a screen displays in a given area. There are numerous combinations of those resolutions with varying widths and heights. HVGA and WQVGA are such famous combinations that might be usually utilized by computer monitor manufacturers and cell screen manufacturers. Despite serving similar purposes, these two have very distinct points of difference between them.

HVGA vs WQVGA

The main difference between HVGA and WQVGA is that they primarily represent two different Video Graphic Arrays. The former is the Half type, while the latter is the Wide type of VGA. Also, HVGA has more pixels and WVGA. Therefore, in terms of the quality of image due to pixel concentration, HVGA is better than WVGA. 

HVGA and WQVGA

HVGA also refers to a half-size VGA (Video Graphics Array). The display screen in HVGA has many combinations of pixels relying upon element ratios. Varying from 480 crosses 320 for 3is to 2 component ratio, to 480 crosses 360 pixels for 4 is to 3 element ratio, to 480 crosses 272 for 16 is to 9 issue ratio and sooner or later 640 cross 240 pixels for 8 is to 3 ratios. The starting pixel aggregate in HVGA is utilized by masses of PDA gadgets. On the other hand, the last of the ratios are utilized by many handheld PC manufacturers.

WQVGA kind of resolution is also referred to as extensive VGA (Video images Array). This type of display has the same top as VGA, which is a 480-pixel peak, but it is wider. This display is generally visible in liquid crystal display projectors and notebooks that effortlessly display websites that might be designed for a window. This is 800 wide in a complete page width. WQVGA is nowadays favored by many mobile set manufacturers.

What is HVGA?

Screen resolutions refer to a wide variety of pixels a screen displays in a given region. Half video graphics array (HVGA) is a display technology common to some handheld gadgets. They’re commonly small monitors used in hand-held gadgets, which include smartphones and private digital assistants (PDA). Some hand-held projectors also use this technology. The most commonplace decision for this sort of screen is 480 x 320 pixels.

This sort of technology is utilized in small monitors and comes in a narrow variety of sizes. Resolutions not unusual to an HVGA device consist of 480 x 320 pixels, 480 x 360 pixels, and 640 x 240 pixels, with the primary being the most common. It’s called 1/2-VGA because, at its general size, it is half the dimensions of the 640 cross 480-pixel screens preferred on a VGA setup.

It has more pixels and hence better picture quality. Smartphones and high-end feature phones mostly use this resolution type. The width is the key dimension here. It is set at about 480 pixels. The height is varied here in this resolution type. 

The higher resolution provides a premium to the tool with an elevated fee. Some projector manufacturers, including Texas instruments, are also utilizing HVGA resolution. 3D pc photos made use of HVGA at some point in the 1980s.

What is WQVGA?

The screen’s resolution is critical since it determines how much data can be displayed on the screen at once. Resolutions have gradually increased in tandem with screen sizes as technology has progressed.

Wide VGA is another name for this resolution (Video Graphics Array). This monitor has the same height as a VGA display, which is 480 pixels tall, but it is wider. Ranging from 800 x 480 to 848, cross 480 and 854 x 480 are some of the most prevalent examples. This display is most typically seen in LCD projectors and notebooks, allowing users to easily view web pages created for an 800 wide window in full page width. Many mobile device manufacturers now choose WVGA.

It is a wide variety of Visual Graphic Arrays. It has fewer pixels, so picture quality is not as good. Low-end smartphones use this type of resolution. The width is varied here in this resolution type. The height is the key dimension here. It is set at about 240 pixels.

In more cheap devices, the lower-end WQVGA is more prevalent because it suits the price range well. In the future, WQVGA resolution will almost certainly go out of favor in favor of higher resolutions. As manufacturers fight for better features at a specific price level, WQVGA is likely to come first.

Main Differences Between HVGA and WQVGA

  1. HVGA is the high variety of Visual Graphic Arrays, while WQVGA is the wide variety of Visual Graphic Arrays.
  2. HVGA has more pixels, and hence better picture quality, whereas WQVGA has fewer pixels, so picture quality is not as good.
  3. Smartphones and high-end feature phones mostly use HVGA type resolution. On the other hand, low-end smartphones use WQVGA type of resolution. 
  4. The width is the key dimension here in HVGA. It is set at about 480 pixels. On the contrary, the width is varied in the WQVGA resolution type.
  5. The height is varied here in the HVGA resolution type, but height is the key dimension in the WQVGA resolution type. It is set at about 240 pixels.

Conclusion

We use abbreviations like HVGA and WQVGA to make it easier to distinguish between resolutions. The primary distinction between HVGA and WQVGA is the number of pixels, with the former having significantly more than the latter. HVGA means Half-size VGA, which has a resolution of half that of VGA. WQVGA, on the other hand, stands for Wide Quarter VGA, which has one-fourth of the resolution of VGA but a wider width to fit a widescreen resolution.

Smartphones and high-end feature phones mostly use HVGA type resolution. On the other hand, low-end smartphones use WQVGA type of resolution. 

Thus, one must consider all these differences between these two VGAs while shopping for them.
