Common Resolution Standards and Key Concepts of LCD Panels
SXGA XGA UVGA SVGA VGA WUXGA FHD WXGA HD WVGA UHD WXSGA These abbreviations are terms used by the display industry to standardize and quickly describe screen resolution
Common Display Resolution Standard Quick Reference Table
SXGA/XGA/UVGA/SVGA/VGA/WUXGA/FHD/WXGA/HD/WVGA/UHD/WXSGA These abbreviations are terms used by the display industry to standardize and quickly describe screen resolution. They mostly stem from the development of a series of display standards.
To make it clear to you, I have organized these resolution standards into a table and arranged them in a rough order of development and clarity.
Common Display Resolution Standard Quick Reference Table
Abbreviation | Entire process | Resolution | Screen ratio | Remarks and Introduction |
VGA | Video Graphics Array | 640 × 480 | 4:3 | The beginning of graphic display has been phased out, but the name "VGA interface" is still used. |
WVGA | Wide VGA | 800 × 480 | About 15:9 | Commonly seen in early smartphones, GPS devices, and portable media players. |
SVGA | Super VGA | 800 × 600 | 4:3 | Th enhanced standard after VGA was widely used in early CRT displays. |
XGA | Extended Graphics Array | 1024 × 768 | 4:3 | The classic standards of early LCD screens and projectors are still in use today with projectors. |
WXGA | Wide XGA | 1280 × 800 | 16:10 | Common resolutions for early entry-level laptops and low-end displays. |
HD / 720p | High Definition | 1280 × 720 | 16:9 | The high-definition standard is a symbol of entering the 16:9 widescreen era. |
SXGA | Super XGA | 1280 × 1024 | 5:4 | Mainly used for early 19 inch square screen LCD displays. |
UXGA | Ultra XGA | 1600 × 1200 | 4:3 | The standard for high-end CRT and 20-21 inch LCD displays is commonly used in color workstations. |
FHD / 1080p | Full High Definition | 1920 × 1080 | 16:9 | Full HD, currently the most mainstream display and TV resolution. |
WUXGA | Wide Ultra XGA | 1920 × 1200 | 16:10 | Compared to FHD, it has more vertical space and is highly favored by designers and programmers. |
WXSGA+ | - | 1680 × 1050 | 16:10 | Regarded as a variant of WSXGA, commonly found on 20-22 inch displays. |
UHD / 4K | Ultra High Definition | 3840 × 2160 | 16:9 | Ultra high definition, the next generation mainstream standard, providing extremely delicate images. |
Understand patterns and key concepts
From the above table, you can observe some patterns in these abbreviations:
1. The meaning of the prefix:
VGA: Graphics array, it is the ancestor.
S (Super/SXGA): means "super", higher than the standard version.
X (eXtended/XGA): stands for "extended" and is better than VGA.
U (Ultra/UXGA): stands for "ultimate" and is higher than Super.
W (Wide): stands for "widescreen", usually in a 16:9 or 16:10 ratio, different from traditional 4:3 or 5:4.
2. Evolution from "High Definition" to "Ultra High Definition":
HD (720p): The threshold for high definition.
FHD (1080p): Full HD, currently the absolute mainstream.
UHD (4K): Ultra high definition, with a resolution four times that of FHD.
3. Changes in screen ratio:
Early standards (VGA, SVGA, XGA) were mostly 4:3 or 5:4, closer to a square shape.
The modern standards (HD, FHD, UHD) are mostly 16:9, which is the mainstream of widescreen entertainment.
16: 10 (such as WXGA, WUXGA) has a place in the office and professional fields because it can provide more vertical space.
How to apply it to practical selection?
After understanding these terms, you will be able to quickly comprehend their screen specifications when selecting a device:
Daily office and audio-visual entertainment: FHD (1920 × 1080) is already sufficient and is the most cost-effective choice.
Professional design, programming, high-end gaming: It is recommended to choose WUXGA (1920 × 1200) or higher, such as 2K (2560 × 1440, not included in this table) and UHD (4K), to obtain more workspace and finer graphics.
Choosing a projector: It should be noted that the standard resolution for many old or commercial projectors is still XGA (1024 × 768), while mainstream home and portable projectors have been upgraded to WXGA (1280 × 800) and FHD (1920 × 1080).
I hope this detailed explanation can help you thoroughly understand these common resolution terms!
