Please I want an answer to this question.

1920x1200 @ 60Hz x 24 bits per pixel = 3.317 Gb/sec
I'll show my work:
1920x1200 = 2,304,000 pixels
2,304,000 x 60 = 138,240,000 pixels per second
138,240,000 x 24 = 3,317,760,000 bits per second, or 3.317 Gb/sec
Single-link DVI maximum speed: 3.96 Gbit/s
As you can see, 1920x1200 at 60Hz is near the limit of single-link DVI, which is why you need to go dual-link DVI to do 2560x1600.
1680x1050 @ 120Hz x 24 bits per pixel = 5.08 Gb/sec
This is why the Samsung 2232rz and Viewsonic 2265wm require dual-link DVI.
1920x1200 @ 120Hz x 24 bits per pixel = 6.63 Gb/sec
Dual-link DVI maximum speed = 7.92 Gbit/s
So, 120Hz 1920x1200 could be done on dual-link DVI.
2560x1600 @ 60Hz x 24 bits per pixel = 5.90 Gb/sec
Falls about midway between 120Hz 1680x1050 and 120Hz 1920x1200.
