Colour corruption Win7 Green tinge.

Im getting the below colour corruption on my laptop.
It doesnt start till i open itunes or watch a home video via mediaplayer/Windows live photo gallery.

It goes away if i log off and log back in. Ive tried uninstalling my nvidia drivers and reinstalling. I dont get the same effect if remove the nvidia drivers and boot up Win7 with no drivers.
This is only a new thing and i have not experienced it before, ive had the laptop for a year (clevo)

As you can see below i get a strange green tint which is showing most on the wallpaper in the below photo in the shape of a raimbow, but it effects everything.

 

Just thought id add that it doesnt happen on the external screen when i connect to an external display, but still displays on the laptop screen when both screens are on.

 

It almost looks like it's reducing the number of colors on the screen which is causing some kind of dithering effect.

 

Do you know what hz a laptop monitor @ 1920x1200 should be? Ive just been playing and i dont seem to get the problem when at 59hz, i think the default is 60hz (its the only other setting for that resolution).

Why give the option of such a small difference?

 

Just noticed when i put it in 59hz mode i get some weird blue lines down the screen, shows up a lot on the Steam application.

 

I've wondered about the 59/60hz as well. I think it has to do with limited internal bandwidth between the monitor and the graphics card but I'm not sure. Anyone else here know what this peculiarity is all about?

 

It seems anything past 195.62 nvidia drivers are causing this effect.
Odd since ive ben using 258.96 onwards for since they came out and not seen this problem till yesterday. :/

Graphics card is a 280m

 

I think its a problem with your notebook as well.

My xps m1730 with 8700gt sli has a similar yellow tint issue, its commonly known and fixed by the vbios.
Its probably just something to do with the actual LVDS serialization and output

 

What can you tell me about the vbios? Is that to do with the video card?

I have a M570TU with a 280m graphics card.

 

I know LCDs are magnet-sensitive, and this looks an awful lot like when I accidentally put magnets up to a CRT. Can anyone confirm this is what it looks like when this happens to an LCD?

 

Since when are LCD's magnet sensitive?

 

No its not magnets, they dont effect LCD's like CRT's. This only happens with nvidia drivers above 195. Unfortunatally drivers 195 and below give the nasty sound stutter.

I have noticed that no matter what drivers i have im getting a very faint blue fuzz across the Steam library page, always in the same place even if i move the page around the screen, its like the fuzz stays with a certain colour. It even happens if i copy and print the screen into paint.

BUT, when the blue fuzz is on the steam page the green haze everywhere else disappears and vice versa, its very odd. It take a bit of faffing about with apps and the net before the green haze happens but the blue Steam fuzz is present right from start up and only stops when the green haze starts! Driving me nuts!

 

Just for the hell of it, have you tried updating your Direct X drivers to the latest revision?

 

Ill give it ago, need to find what my version is and where the latest versions are. My dxdiag says 11, but im sure thats not the complete bersion number. Will check it out.

 

Is this the latest dx version?

Download Confirmation


DirectX End-User Runtimes (June 2010)

 

That is correct.

 

I got something like this when my graphic card was overheating a few years ago in fact it leads to a dead memory onto the gpu this dead component was giving me this kind of screen at windows desktop
but as you don't seems to have the problem with an external screen
I would think it is more a problem related to the laptop screen than a driver or software
but you don't get the same effect if you remove the nvidia drivers and boot up Win7 with no drivers
so probably not

you said :
It doesnt start till i open itunes or watch a home video via mediaplayer/Windows live photo gallery.

does it mean till you push the card to the point that it overheat?
does it start if you just wait at windows desktop level?
Have you tried other demanding software?
windows driver are kind of basic drivers which don't push the card which could tend again towards an overheating problem
an overheating problem could be due to a lack of contact with the heatsink due to the dissapearance of the thermal paste with time as well
but you don't get it on the external screen, don't get any blue screen after a while nor any artifact
so probably not

have you tried older versions of nvidia drivers?
have you installed/uninstalled any other software recently which could lead to some conflicts?


so to sum up:
dead component = probably not
overheating problem = probably not
external problem = maybe
software/driver problem = maybe
laptop screen problem = maybe

 

I have completly reinstalled Win7 and even overwritten that with XP to see if i got the same problem... i did get the same problems.

Im sure its not over heating, it doesnt trigger it when playing games, only with 'time' or itunes seems to trigger it.

I have stopped the green fuzz happening with 195 drivers, anything over 195 makes the green fuzz happen. Although the problem with the blue lines going across the Steam application are there with all drivers; although as i said above they blue lines disappear when the green fuzz appears.

Also i notice a strange blue line going up the steam application page when i turn the monitor to 59hz (from 60hz) this like only seems to happen with the Steam application and only in a certain place, i.e. scrolling can move the line out of view. Its like some hardware doesnt like something about the steam colours or something. Ive even done a print screen and pasted into paint, it does excatally the same thing.

Its very very odd. Im leaning towards a problem with the screen, but one that only happens in certain conditions.

 

so then stick with the 195 drivers as it seems to be a driver problem with your graphic card
The nvidia website could say something about some incompatibilities with your graphic card

steam problem:
have you installed any antivirus after reinstalling windows?

if you have the firefox browser add the addon quickjava
it allows you to block separately javascript, java, flash, silverlight, images, css
disable only one each time (red means disabled) under the steam page and notice which feature make the blue lines disappear

another thing to try could be to modify the colour adjustment of your screen from the nvidia utility
by disabling each colour at the time (red, green, blue)
you could modify the hue, the brightness, the contrast etc to see what it is happening

 

Unfortunatally this problem started over night, nothing had been updated and no drivers had changed. Had worked perfectally for months. So that would write off driver problems. I reinstalled win7 and had it totally clean (no other software running), did the same with XP got the same problems.

The two problems green haze and blue fuzz are connected somehow, as one cancels the other out in certain circumstances. And the fact that it doesnt happen on an external monitor suguests a screen fault too.

 

you're right it's probably the screen
it seems to be related to the frequency of the screen as blue lines starts when you change to 59Hz

but you said it stopped happening if you rolled back to 195 drivers, right?

try to modify the colors to see what happen

 

Na, its the green haze stops with 195 and earlier. The blue fuzz only stops when the green haze kicks in! (even then there is an odd 'uneffected by the green haze' line through the green haze right where the blue line used to be) Its totally mad, ive had a heck of a time trying to explain it to the returns people.

Ive got it all boxed up now, so i think ill leave it to them. Ive been playing around with it for 5 days solid now, since i gashed up my knee ive not had a lot else to do!

 

I wish them good luck
