Problem with connection of LCD projector

[shrikanty]

I have dell inspiron N5010 with windows 7. I want to connect Sony LCD projector to my laptop. But when i connect cable of projector to laptop, It does not get any signal from laptop. projector is working properly with other laptops.  I have button on my laptop for selecting the display mode but it is not working. I have connected laptop earlier when i was having Win XP. I think this problem is because some drivers are missing, but i dont know which are those drivers. Please help.

Have you tried a normal monitor on the laptop's output port, to see if you get a display from that?

[shrikanty]

i tried that after your suggestion. Normal monitor is also not getting any signal from laptop.

OK, so at least we know it's something with the laptop, not the projector or cable - unless you used the same cable for both?
Go to the start menu, right click Computer, click Manage, then go to Device Manager.  Do you have any devices with yellow exclamation or question marks next to them?  It's possible that the graphics drivers aren't installed.  If you do, right click on them go to properties, go to the details tab, change the dropdown to Hardware IDs, and post the first line here so we can identify the device and direct you to the appropriate driver.

I have yellow mark next to bluetooth periferal device. Hardware ID for that is

BTHENUM\{00001132-0000-1000-8000-00805f9b34fb}_LOCALMFG&000f

but i think it does not have anything to do with display. So Below are hardware IDs for display adapter and monitor. Hope these might give any idea to you.

1. Display adapter
PCI\VEN_8086&DEV_0046&SUBSYS_04471028&REV_18
PCI\VEN_8086&DEV_0046&SUBSYS_04471028
PCI\VEN_8086&DEV_0046&CC_030000
PCI\VEN_8086&DEV_0046&CC_0300

2. Monitors
Monitor\LGD0266

Alright, that is helpful, because at least it shows your graphics drivers are installed.  It could be worth updating or reinstalling them from the Intel website.
If you right click on the desktop, and go to screen resolution, is the second display shown there, or not?

[shrikanty]

There is only one screen in screen resolution. Dropdown menu shows only Generic PnP monitor on standard VGA graphics adapter.

OK, sounds like your graphics drivers aren't properly installed after all.
See here for the driver download page, install that and it should help

i have installed the drivers suggested by you. But it is still showing only one screen in screen resolution.
