Title: Problem with connection of LCD projector
Post by: shrikanty on July 02, 2013, 10:37:13 AM: 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.

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.

Post by: shrikanty on July 05, 2013, 03:05:52 AM: 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

If you right click on the desktop, and go to screen resolution, is the second display shown there, or not?

See here (https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3231&DwnldID=22521&ProductFamily=Graphics&ProductLine=Laptop+graphics+drivers&ProductProduct=Intel%c2%ae+Core%e2%84%a2+Processors+with+Intel%c2%ae+HD+Graphics&lang=eng) for the driver download page, install that and it should help :)
