Hi.
I'm new to this forum (and to the site as well...) & not so good with english, so forgive me for that...

I have 2 questions about LCD screens, and the technolegy behind them.

Starting with the specific one:
a. I've bought a Samsung 226BW (22" Wide LCD) a long time ago, and just lately i've notice I have a HD-out in my graphic-card (RADEON 9000 PRO).
I pluged the screen to the CP on the spot, without turn it off (wrong,I know), and when I tried to switch to Digital mode - nothing happend. The screen was black. I tried to turn it and the comp off and on - not working. I managed some solution by updating the Graphic-card and the screen driver, and the screen actually working in Digital mode.
But not all perfect.
My problem now is that during the start-up of the CP, the whole BIOS proccess - the screen is blank, and its power-light blinks, as its not getting any power. Just when I reach to the Users Login (windows XP) screen - it suddenly turn on. Is this how it should be? I don't think so...

And a bit more general question:
b. In short -what's the difference between the Digital and the Analog mode, anyway? I know that in Digital mode, the screen get the data with no need to convert it, but what is that saying? because, to tell the truth - I havn't notice any difference between the two. I'd happy to reffered to a summerized article that explain the basic of that...

Many thanx!!

Welcome to the AT Forums, cheetah64d.:)

a) I'm afraid I don't have an answer.

b) The advantage of digital mode is that everything is how it should be with subpixel-perfect accuracy. Digital->Analog->Digital conversion involves a certain loss of quality due to the conversion and natural issues (e.g. interference) with transmitting a signal via analog. The result is that a pure digital signal will have perfect colors, perfect pixel placement, and such, while using analog mode will degrade these all slightly. It doesn't mean that analog mode is unusable, but you want to stick with digital when possible.
