hey guys, I need some help here, I get a Samsung P2070 LCD monitor and when I plug it on the DVI of my GeFroce4 MX420 (running jackalope), it shrink, it's continiously blinking.... On WinXP I had to set a "custom timing" to CVT-RB to make it work... now on the linux nvidia control panel that option is not there, so I check a lot of forums and I beleive to understand that I have to manually set this on the xorg.conf file, anyone can help me?

Dot Acceptable
TFT-LCD panels manufactured by using advanced semiconductor technology with precision of 1ppm (one millionth) above are used for this product. But the pixels of RED, GREEN, BLUE and WHITE color appear to be bright sometimes or some black pixels may be seen. This is not from bad quality and you can use it without any problems.
For example, the number of TFT-LCD sub pixels contained in this product are 4,320,000.
