From Webopedia,

XGA: Short for extended graphics array, a high-resolution graphics standard introduced by IBM in 1990. XGA was designed to replace the older 8514/A video standard. It provides the same resolutions (640 by 480 or 1024 by 768 pixels), but supports more simultaneous colors (65 thousand compared to 8514/A's 256 colors). In addition, XGA allows monitors to be non-interlaced.

SXGA: Short for Super Extended Graphics Array, a display specification that is capable of displaying 1280 x 1024 resolution, or approximately 1.3 million pixels.

UXGA: Short for Ultra Extended Graphics Array, a display specification that is capable of displaying 1600 x 1200 resolution, or approximately 1.9 million pixels.

So, other than resolution, that would make the difference.. nothing??


Incidentally that would explain the +, if SVGA is 1280x1024 then it makes sense that the SXGA+ is slightly more but less than the UXGA...

Precisely the reason for my question.

SXGA+ is what Dell calls their extended SXGA resolution of 1400x1050.

Last time I remember, not sure if IBM is continually setting the standards for the monitors or whether the manufacturers has created their own standards body for UXGA and current.
Minor point for the consumer but may impact direction of technology development. ie. The term RAID as an example.

Actually, now that I thought about it a little more,
It can seriously make an impact on the consumer.
If there are any wars of competing standards,
Consumers can be left holding the bag. ie. VHS versus Beta tape recorders and the original wars over the CDR standards and DVD standards would be another example.

IBM developed the original standards but they defined VGA at 640x480x16 and 320x240x256 and 8514 at 1024x768 interlaced when the original AT first came out. Several clone companies started making cards and monitors that began to fill in the gaps but they were not always compatable.

Shortly thereafter the VESA organization was formed and a set of standard resolutions were defined. They also defined a special ISA bus extension for video cards and a set of INT10 calls for graphics display functions. Both of these see very little use today. VESA still exists today but with significantly less clout than they once had. I believe that they also defined the standard for plug-and-play monitors but I am not certain.

Apparently you misunderstood the original question. He asked, "Is there any difference other than resolution??"

I believe that the correct answer is NO.

If VESA did set the standards then my original statement does apply,

Different organization setting the standards.
I expected different organization taking over the setting of standards, just not sure as when it occurred.

Never mind.

The original poster already received an answer and acknowledged it.

Yup!

Just remembering what happened the last time the definition of RAID was brought up. Something that was minor spilled over to the CompTIA exams.

I'm not sure if I completely understand the question either... If you're looking at monitors and one claims XGA and another claims SXGA, there may still be other difference. Between manufacturers and models, brightness, contrast, switching speed, pixel size, viewing angle, power consumption, etc, may vary considerably. A high-quality XGA display may very well be better than a cheap SXGA. It's best to take a look in person and see which ones you think are best.
