Will a flat screen monitor require a special interface on the video card?

Hi Everyone;

         I am thinking about replacing my current CRT monitor with a flatscreen monitor which brings me to the point of this question.   If I do this, will I also need to replace my AGP video card?  Or, will the flatscreen monitor have the same connector configuration as the CRT monitor?

          Any shared ideas or thoughts to this question will be appreciated.

          Thank you

Most LCDs have the same VGA connection as the CRT monitors.  The more expensive ones will have VGA and DVI which is a digital connection.  If you want to use DVI and your card does not support it, you will have to upgrade your card.

Hi

      Thanks so much for the reply.  Just out of curiousity, what would be the advantages and disadvantages of having a flat screen or LCD monitor?

LCDs to me seem to strain my eyes less than a CRT would.  There is also the advantage of them being lighter, and smaller.  They take up considerably less space than a CRT would.  The company I worked for stopped ordering CRTs because the price difference wasn't that great anymore.

Hi There;

         Thank you so much for the followup.  Just one more followup question which should help provide proper closure to this post.  What exactly does the digital connection for the card do in this situation?  Apparently, the video card installed on this pc has this connection.

On small displays, it is hard to tell the difference between VGA and DVI, but for larger screens, especially 42" and above, DVI keeps the signal in the digital domain and thus looks sharper and clearer.

i have had a question here about a guy complaining he could not use an LCD, because the screen gave him headache.
in general, LCD's have a higher contrast than CRT; but they also need to operate on their native resolution for best display, and sharpness. lower or higher resolutions give poor image quality
Many users that work with graphic applications prefer still CRT.
It is not a clear cut definition, but more of a preference
I hope this helps a bit  George

The digital connection will provide a clearer, truer picture than the standard analog connection.  Definitely use the digital if you can.  If the signal is analog, it can be interpreted differently by each monitor (colors may be off), and is more prone to signal degredation/intereferance.

I was curious how much better of a picture was provided by DVI, so I installed two of the exact same model LCDs on a system, and ran one through the card's VGA output, and one through the DVI output.  The DVI-signaled monitor was much brighter, clearer, and all around gave a noticeably better picture than the standard VGA analog picture.

Hope this helps.  :)

Hi Everyone;

         Thanks so much for the shared input regarding the comparisons made between LCD and CRT monitors.  Each one of the points presented certainly made sense.  From what I gather from some of what has been said here, whether someone prefers to use a LCD or CRT monitor would depend upon the application.  For instance, as nobus mentioned, many users of graphic applications still prefer to use CRT monitors.  While this is certainly a good point, I think the majority of people who responded to this question certainly are in favor of LCD monitors because of the crisp picture given with clearly defined colors and depth.  In fact, I am using a LCD monitor now which belongs to a friend.  It is much better picture quality and less strain on the eyes as compared to my regular CRT monitor.  Of the two, I certainly prefer the LCD or flatscreen monitor.

            In closing, thanks once again everyone for the thought provoking replies given to this thread.  I certainly learned a great deal here.
