X60s can not work with the 1680x1050 LCD

Hi forks,
I am using the X60s, it's been performing quite well. Problem occurs after i bought an 20.1 WXSGA+ 1680x1050 to use as a second monitor. The external widecreen monitor (connected via the VGA) can not display properly when i choose the 1680x1050 resolution for the external LCD monitor.
Anybody know how to solve this problems? Please help.
Thanks.

 

Does it work for resolutions lower then 1680x1050 ?
If so, try upgrading your driver to the lastest.

This was in the spec sheet.
Also try switching to the main display I hope it works this way.

 

Hi mujtaba,
Thanks for your reply.
I tried the LCD with the 1440x900 and it worked but the displayed image was not clear since 1440x900 is not the native resolution of the LCD monitor. When i switched to 1680x1050, the image was displayed on only half of the LCD screen.
So far, 2 things can be the problem maker:
1 - Graphic card itself: but from the graphic accelerator 950, it seem okay with the 1680x1050
2 - Lenovo X60 configuration (BIOS,etc.) can not support the wide screen. (it's possible cause the image was shrinked and couldn't expand to the wide scale). I tried the LCD with the other widescreen laptop from TOSHIBA and it works well in 1680x1050 resolution.
I just guess and dun know how to solve the problem. I spent days to update my system to the lastest versions but no hope.
If you have any ideas, please advise me.

 

are you using both screens or only the 20inch screen?

 

Hi paqtrick22,
I tried 2 cases, both screens together and 20.1 LCD only. The 20.1 did not work in any cases.
