Windows 7: Secondary VGA monitor on and recognized but black!

Secondary VGA monitor on and recognized but black!

Greetings all, new here... Generally fend for myself when it come to these sorts of things but after hours of following threads and uninstalling/reinstalling drivers, connecting, disconnecting, I figured I'd try to get some help.

Just bought this machine, Asus K50IN laptop with an Nvidia G102M 512mb graphics card in it. I work as a DJ and VJ and this is my primary machine and means of living, it needs to be reliable in different scenarios and work its a*s off an average of 5 nights a week.

So long story short: bought machine, installed a clean version of Win 7 Ultimate and then all relevant drivers... Things worked great the first week. No issues. Then 2 nights ago I plugged into my normal rig (a toshiba projector with an extension monitor daisy chained to it at one of the clubs I work in) and everything was tinted bright pink. I messed with it for a few minutes but I was late already and there were people to entertain so I played anyway with this weird pink tint over everything.

Last night, back to work again... Came early to try and fix the bugger before I would be pressured to play. Adjusted settings in Nvidia control panel, messed with color, resolution, etc. At some point while doing this the secondary display went black and never came back on.

I have reset all settings, completely uninstalled, updated, etc etc etc... Even on my secondary monitor at home, same deal. Monitor is on and says all is fine and working properly but my desktop won't extend to the second monitor. It stays black. Mouse rolls over there then takes its time coming back. It's on, and the computer thinks everything is hunky dory.

I've tried about everything software wise I can think of and am starting to think the VGA out may be buggered.

Anyone???

Hi nzl! I am a new poster here as well!

I am inclined to agree that your "VGA out may be buggered". If you are plugging two separate known working "monitors" into your laptop vga port and neither is displaying anything, then it is pretty good deductive analysis that the vga port is "buggered".

The reason I agree with your final (if hesitant) analysis is that, after the initial install, you stated that everything worked fine. Then after a bit things went pink. And then nothing. This sounds like a gradual degradation of the hardware and finally failure.

That being said; when you say you have installed the latest drivers, are you saying actual nVidia drivers or MS Windows 7 nVidia drivers?

It sounds like a hardware failure. However, if you want to make sure, do a system restore or a repair install then install the latest drivers from NVIDIA's website. If it still doesn't work, then it's most likely a hw issue.

Thanks to both of you...

I did restore to before the problem initially then did a repair OS install today before I made this post. I have tried literally every driver from the ones included with my hardware to those available on the Asus website for the same model (Win 7 x64 over Vista x64 which is all I was supplied with initially) to those on the nVidia website and finally MS Updates as the final straw.

I'm going with buggered... Seems odd for a machine this new to go south so rapidly but manufacturing standards being what they are I suppose there's a reasonable chance of a bad solder or bunk component finding its way in there. Such is life.

Also realizing I payed little attention to the accessibility of components on this model when making my decision to purchase. Looking at the back, well there's no reason to look at the back except to locate the screw holes. The entire face needs to be disassembled to access any of the internal components. Not an issue to many, but the environments I run this machine in are anything but healthy... Would be nice to at least be able to reach the exhaust for cleaning without a total teardown, those warranties don't last forever.

Thanks again y'all...

nzl,

You mentioned that you bought the machine, did a fresh install of Windows 7 and all relevent drivers. By any chance was the version of the nVidia driver 196.75?

I ask because there is a known issue with that driver version "frying" video cards.

From what I understand, it completely toasts standalone cards. Perhaps, with integrated video, it only affected your VGA port? Assuming, of course, this is the version of driver you used...
