DVI Graphics Card better image quality?

I asked a question earlier regarding whether DVI output on a graphics card produces better image quality on a Flat Panel LCD monitor.
I was told:
the video signal is not converted to the SVGA signal, and then to the DVI signal required by the LCD.The fewer conversions, the less chance for signal degradation; thus, better image quality.

Well, we have a Dell 15" Flat Panel Display and are using the DVI out on the graphics card. The image quality is not as good as a CRT. I can see separations between the lines in individual letters - so I guess it's pixelated. The display on a laptop looks the best and a CRT looks better and the DVI/Flat Panel looks bad. Please tell me if you think it could be a setting I am missing, or perhaps the quality of the flat panel.
Thanks

Flat panel technology is getting better all the time but CRT still rules when it comes to image quality. Also, whether you're using DVI or analog is not what's most important for image quality because refresh rates don't apply to LCDs. Their pixels are either on or off. When there is no screen motion the pixels are static. When screen motion is present the pixels switch to different color combinations. If this doesn't happen fast enough you'll get streaking.
What needs to be known is the optimal screen resolution for your flat panel. Even when set at optimal resolution it still won't look as good as a CRT.

Well the main benifit of LCD is that it's easier on your eyes & takes less space, not a better picture necessarily, although there shouldn't be a noticable difference in picture quality unless your playing games. CRT are better for games so far.

Have you checked both Dell & your video card manufacturer for driver or firmware updates?

Also note: Their are only 3 company's that make LCD monitors & Dell isn't one of them but they are the only ones who can provide you with any driver updates.

As for settings I would check for drivers first & if that doesn't help then it likely is a setting but you'll need to refer to the video card & monitor manuals to determine whats correct for your PC.

Hi are you saying that if you have say a "l" that you can see the individual dots that go to make up the "l" if this is so then you need to set the resolution higher if the LCD does not allow for higher resolutions then you are stuck. If it is not this problem can you elaborate.
