LCD display question

[Jeff Mings]

    Most of the cheaper LCD displays take analog input via a  mini D-sub 
15 pin connector and look unfocused and inferior to most laptop 
displays.  I'm assuming that the only way to get a really crisp display 
is to use a video card with a DVI connector that can drive the LCD 
directly, without any loss of clarity from a conversion from 
digital-analog and back.  Have any of you personally compared powering 
LCD displays directly via DVI versus analog signals from an ordinary vga 
card?

Thanks,
