2405 digital ?

k i wanted to know if anolog or digital makes a difference in quality and i read this

This is a simplified explination but it shows how you can push 2048x1536 down a DVI-I or DVI-A cable

2048x1536x85 = 267386880Hz or 267.4MHz (asuming no blanking space), a single link DVI-D connection has a 165MHz dot clock to play with so that obviously isn't going to work, PCs have a trick up their sleeve which is to strip almost all blanking information out of the signal allowing access to resolutions beyond 1600x1200, (fwiw 1920x1200 is basically the highest standard resolution available beyond 1600x1200 which a single DVI-D link supports as 1920x1440 requires a shade under 166MHz for the displayed pixels)

So how do we get to 2048x1536 @ 85Hz? Well 267.4MHz < 400MHz, add a little in for your blanking porches etc. and you have a near 400MHz dot clock. 400MHz being the typical analogue RAMDAC clock these days, a DVI-I or DVI-A cable can transmit that kind of bandwidth, so simply the graphics card drops into analogue mode when you try to go over a set thresh-hold.

if this is true then there is no way to get a digital signal at 1900x1200 and since this monitor doesnt support dual link its basically impossible to get a digital signal?

also, i dont know if digital or anolog makes any differences i just figure digital would be better

Did you miss this part?

fwiw 1920x1200 is basically the highest standard resolution available beyond 1600x1200 which a single DVI-D link supports
