| 593889 | 2007-09-22 03:11:00 | Hi guys, Odd problem just cropped up on Vista. VGA Out now no longer works (it was working last night when I went to bed, not when I wake up). I have tried with two different VGA cables, and two different screens (one generic 17" LCD, and my main one, a Dell 2407 WFP), neither of them work. The 2407WFP works with my older, Dell 630m laptop, so the problem is not with the screen or cable. The laptop is a Dell Vostro 1400 with a GeForce 8400m GS graphics controller. I've uninstalled the driver, rebooted, tried to get VGA Out with no driver, no go (by using the Display Settings within Vista, or pressing Fn+F8 on the keyboard). I also tried uninstalling the driver in safe mode, to ensure everything was removed. Still no go. I've tried several driver versions: 165.01, 162.18 and 162.13. 3D acceleration works, so the driver is functioning correctly. When I power on the screen, the VGA input light is orange (means no input). I see no change when I connect/disconnect the VGA cable or enable/disable VGA out on my laptop. I tried pressing Fn+F8 whilst in the BIOS to see if I could do it then. Laptop screen went black, no output on my external monitor. Though, this may be expected, as I'm not sure if VGA out is supposed to work before Windows has loaded. Can VGA ports be blown? What should I try next? |

And if the video drivers are installed, something should come up on the external monitor (and if TV out is enabled in the settings / once you log into Windows (not as soon as you boot the system up). |

| 593891 | 2007-09-22 03:43:00 | Thats the thing, if I enable VGA out (via the keyboard combination, or the Windows display settings), I don't see anything on my external monitor for about 15 seconds, then it switches back to the laptop screen (presumably this is when the "Do you want to keep these settings? Your new settings will be reversed in 15 seconds" box is displayed). | asubstitute (12850) | ||
| 593892 | 2007-09-22 05:39:00 | I noticed everytime I attempt video out, I get this in the event manager: The Desktop Window Manager was unable to start because the desktop composition setting is disabled Looking into it. Edit: www.google.co.nz t+because+the+desktop+composition+setting+is+disab led%22&btnG=Search&meta= Fantastic.... Not much to see there anyway, just Your search - "The Desktop Window Manager was unable to start because the desktop composition setting is disabled" - did not match any documents. |

| 593894 | 2007-09-22 11:56:00 | This error message is not related. I enabled Aero, and it no longer came up. | asubstitute (12850) | ||
| 593895 | 2007-09-23 09:48:00 | It sounds like your VGA port is dead, I'm afraid. You won't have "blown" it, it will have just developed a fault. If it's under warranty, take it back and have it fixed. The screen switching should work in the BIOS, and the fact that it does not indicates that it is a hardware fault, not software. |
