XGA vs WXGA vs WUXGA: Resolution Differences Explained

This article breaks down the differences between XGA, WXGA, and WUXGA display resolutions. These acronyms, along with others like “High Definition” and “Quad Extended Graphics Array,” can be confusing. Let’s clarify what each one means.

Introduction:

Display resolution refers to the width and height of a visual display (like a monitor) measured in pixels. A higher display resolution on the same-sized screen results in sharper images and finer details. XGA, WXGA, and WUXGA all fall under the “Extended Graphics Array” umbrella but differ in their specific resolutions and aspect ratios.

XGA

• Full Form: Extended Graphics Array
• XGA is an IBM display standard that supports a resolution of 1024 x 768 pixels.
• It maintains an aspect ratio of 4:3 with square pixels.
• A later version, XGA-2, improved color output by adding a 24-bit DAC, supporting 256 grayscale levels instead of the original 64.

WXGA

• Full Form: Wide Extended Graphics Array
• WXGA is a non-standard resolution derived from the XGA standard.
• The key feature of WXGA is its wide aspect ratio.
• WXGA is commonly found in LCD TVs and widescreen LCD monitors.
• Common WXGA resolutions include: 1366 x 768, 1360 x 768, 1280 x 800, and 1280 x 720.

WUXGA

• Full Form: Widescreen Ultra Extended Graphics Array
• WUXGA is a widescreen version of UXGA.
• It boasts a high display resolution of 1920 x 1200 pixels.
• It has an aspect ratio of 16:10.
• WUXGA is often used in HDTVs (High Definition Televisions), LCD TVs, and high-resolution monitors.
