View Full Version : Colour Corruption

Hi

I have two TFT screens attached to my Windows PC. The main one is a Viewsonic connected via a digital connection and the second an LG connected via an analog (it's all this one has) to my ATI Radeon 9600 graphics card with Windows XP.

Everything has been running fine for some time, years in fact, then a couple of days ago the colours on the Viewsonic went funny with a green cast replacing the grey tones. On running the Viewsonic monitor test the centre graduation bar shows white going to grey fine until it hits 40% then it goes green coloured, but still graduating in colour.

For example the border around the box I am typing in appears dark green, but move it over to my second monitor it displays correctly at a blue grey background.

I changed leads etc. in an attempt to track this down. I noticed that if I moved any program window over onto the second monitor, the LG, it displayed the colours correctly, so I assumed it was the Viewsonic at fault.

However upon changing the configuration via the ATI's Catalyst Software and making the LG my main monitor, windows start menu on this one etc. the fault now jumps to this monitor with the Viewsonic now displaying correctly.

I realise this is some form of corruption but I hav'n't a clue which part to look to repair. I guess its a corruption of the desktop but how would I go about fixing it.

Thanks in advance.

dodgy lead or connection most probably.

Hi

Thanks for your reply, but as I said in my post I did check these, even swapping them around.
Also I can't see how they (leads) wouldn't account for the fact that whichever is designated as the main screen is the one that gets the corruption to be honest.

It's seems to have cured itself anyway. I reinstalled the ATI Catalyst Software and looking at the 3D settings and changing a few, then back again to what it was before kicked it back to the correct colours.

Bl**dy computers. Thanks for your reply anyway.

All the best.

OK, glad you got it sorted.

I had the same problem with a PC at my last job and it was caused by a loose connection between the VGA lead, VGA-DVI converter and the DVI input on the card. Unless the PC was pushed back hard against the wall so that the lead couldn't move I would start the day with a normal picture and end the day with either a pink or green one. I've also known the actual GFX card to become loose in the slot because of the weight of two leads and VGA-DVI adapters so that might be something else to check.
