I had been looking around for specs of the Dell Inspiron to get a clue
and I noticed a video acronym in the specs: UXGA. Being familiar with
video acronyms like VGA (Video Graphics Array), SVGA (Super Video
Graphics Array), and others, UXGA (Ultra Extended Graphics Special)
sounded new to me. I researched and found that these different video
protocols have limits to their resolution. It is explained in the
Howstuffworks link below:
Howstuffworks "How Computer Monitors Work" - Diplay Technology
- This is page 2 of an article about computer monitors, you can go
throught the other pages using the links below the "How Computer
Monitors Work" title.
UXGA - Webopedia.com
- Definition of UXGA.
Another reference to Video resolutions:
The PC Technology Guide - Multimedia Graphics Cards
The Dell Inspiron you have has UXGA display. Inspiron series notebooks
were among the first to carry the technology, mentioned in one article
UXGA LCD Panels - History of articles by PC Mag
Dell Inspiron 5150 (MPN-5150RH) PC Notebook Specs - DealTime
I think this is what separates desktop LCD monitors from laptop LCDs;
laptops that can support the 1600 x 1200 resolution have UXGA video
support. Those that have up to 1280 x 1024 do not have UXGA, they have
only XGA (Extended Graphics Array). I've seen some 17" desktop CRTs
that have UXGA, like the Viewsonic PF775B (which costs an arm and a
leg I'm sure), but it doesn't seem to have been applied to desktop
LCDs 19" and below. I could find only 20"-above that have UXGA.
I'm sure you want to know the reason for not applying UXGA to 19" and lower.
I think these are the reasons UXGA is not applied to small monitors
(some reasons are my opinion):
- The demand is not that great for 1600 x 1200 small monitors.
- If you set the small monitor at 1600 x 1200, objects will become too
small to see clearly. Fonts will become too small to read comfortably.
- Graphic artists tend to say CRT is still superior to LCDs in
sharpness, so it seems better to apply high-resolutions to CRT
monitors, as they are more used and prefered. UXGA tends to be used in
19"-above (though I've seen a 17" Samsung with 1600x1200) on CRT and
- LCDs and UXGA are expensive. Customers tend to go for less expensive
XGA/SXGA CRT monitors, since many are satisfied with 1280 x 1024 after
- For the Dell Inspiron, I believe it's designed to be used by
graphics users who need a laptop. 1600 x 1200 certainly gives a lot of
graphice detail on a small screen. But then, there wouldn't be many
people who need that feature. It might also be a product meant to make
Dell proud with its advanced features.
