Here is my situation: I've connected two samsung monitors to my laptop, both monitors function perfectly when connected alone, but when I connect both, bottom half of 24" monitor goes black, also mouse pointer is displayed on it but windows\desktop are not.

Any ideas what could cause it?

When you say it goes blacvk. Does it shrink the picture down into just the top half or do you lose half the picture? – Joe Taylor Aug 21 '12 at 12:12
Just lose bottom half of picture, and as I told, mouse is displayed on dead half. Sometimes bottom half blinked showing me desktop background image. – Viller Aug 21 '12 at 12:21
What operating system is this? – millimoose Aug 21 '12 at 12:25
Windows 7 home basic (shame on me) – Viller Aug 21 '12 at 12:31
Have you tried upgrading your Graphics Card Drivers? From the manufacturers website? – Joe Taylor Aug 21 '12 at 12:52

When two monitors(with diffrent resolution) are connected the display resolution will be smaller amoung them;so monitor having bigger resolution have some blank space.

But it's not true. I could configure resolution for each monitor in settings. And I successfully had connected monitor to laptop so I had two screens (1600x900 and 1980x1020) – Viller Aug 21 '12 at 12:23
do you extend the display or display same screen on both? – JITHIN JOSE Aug 22 '12 at 3:20

Thanks, but it's just an instruction how to use dual screen settings, luckily I know it. The question was about another issue, after I did all configurations. – Viller Aug 22 '12 at 6:23
