Common Projector Resolutions
Let’s discuss the different resolution terms and what they mean for projection.
SVGA which stands for Super Video Graphics Array - one of the first resolution standards at 800 X 600 pixels with a 4:3 aspect ratio.
XGA stands for Extended Graphics Array - the next generation after SVGA which has the same 4:3 aspect ratio but the resolution is better at 1024 X 768.
WXGA which stands for Wide Extended Graphics Array -- the next generation after XGA, and one of the most common resolutions especially on entry level projectors, with a 16:10 aspect ratio and 1280 X 800 pixels. This ratio is used on widescreen images since there are almost twice as many horizontal pixels than vertical pixels.
FHD which stands for short Full High Definition or it is sometimes called 1080p resolution. It offers an aspect ratio of 16:9 and 1920 X 1080 pixels.
WUXGA - stands for Widescreen Ultra Extended Graphics Array -- offers an aspect ratio of 16:10 and 1920 X 1200 pixels.
UHD stands for Ultra High Definition. It is often referred to as 4K in consumer applications but this is different from the 4K production standard. This is two times the width and height of the previous Full HD consumer standard which was defined as 1920 x 1080 pixels. UHD has an aspect ratio of 16:9 and the resolution is 3840 X 2160 pixels.
