DVI versus Analog
This debate comes up every few weeks in the forums or an email or some other publication. Many people claim that DVI connections inhibit the use of OSD controls, including contrast and brightness.On the contrary, almost every monitor that has a DVI connection also comes bundled with software. Because DVI connections give you a truer replication of the signal intended by the video card, adjustments should be made on the computer. The bundled software often does this magnificently by adjusting gamma, contrast, brightness, etc. Since a lot of manufacturers were pressured to allow consumers to modify the digital signal anyway, some new LCDs allow you to also modify contrast and brightness while using the DVI connection.
Another misnomer is the rumor that analog inputs produce more accurate colors than DVI inputs. Some people say the analog produces richer tones because analog is more capable of conveying an infinite amount of shades while a digital signal can produce only on or off. For CRTs, this is very true. For LCDs, this is somewhat misleading. Your video card produces an analog signal on the 15-pin cable, but the signal is converted back to digital by the signal processor on the LCD. As a result, the benefits of an analog signal are completely negated, and the only color “enhancements” you will notice constitute inference on the cable.

#5 fixed it - sorry.#7 fixed that one too. Yeah rubbing pixels really doesnt do much good. I think NewEgg is going to be pissed when they find out I messed up their monitor pretty good.
#6 Say it aint so!! We want to be the only ones ;)

Finally! It took long enough for you to get this out :). Great article, finally an article about LCD's which isn't full of opinion and hearsay.dvinnen - Thursday, September 4, 2003 - link
ok, maybie you did mean that. Hard to tell, you say you scuffed the monitor, then go on to tell other people how to do it...I problay just need some sleep...

Rubbing the pixils does more good then harm then?<<<Personally, it seems that rubbing the pixels does more good than harm so continue at your own risk.>>>
Might want to fix that one

good to hear it. Seems like alot of the hardware sites are getting there act together.Anonymous User - Thursday, September 4, 2003 - link
On page 6, where you talk about the cables in the picture (the sentence right below the picture), shouldn't the good cable be the *upper* one or am I missing something?KristopherKubicki - Thursday, September 4, 2003 - link
Yeah, new editors and kind of a revamped AT staff. We went through a lull period after we lost Matthew, but now we have some really good writers and a lot of great content to write about.Just wait till Computex and COMDEX - 3 and 4 reviews per day sounds about right.
