My girlfriend has an external monitor connected to her laptop (Vista) that has worked fine for over three months. Today, whenever we plug it in, everything has a red background as if viewing through rose tinted spectacles. :0)
The monitor works fine when connected to my PC so obviously it is a problem with her laptop....but what could it be, please?
Well, as stated earlier, the fact that the monitor worked fine on my laptop with the same lead led to me thinking that the lead and monitor were ok.
However, I have just tried a different cable and get exactly the ame thing, Im afraid. So...could it be the VGA port on my girlfriend's laptop which is at fault?
Could be a broken or dry joint on the laptop port. With the monitor connected try wiggling the connector. Not the solution I know but if you get a proper display for a few seconds then you will know the probable fault. Worth a try.
Ok, I tried blowing the laptop VGA port with compressed air, hoping to free something up but no luck Im afraid. It was being unplugged and plugged in about once per week and there is no place to screw the connector 'in' to the laptop so perhaps one of the pin holes is damaged. Is there any 'workaround' that can enable a second screen to be plugged in?
If the display is good on the laptop then there is this as an alternative. For me it's too expensive and I've never tried it and as a laptop's life is usually shorter than a desktop I personally wouldn't go for it. Having Vista as an OS suggests the laptop is a few years old anyway.
