I was watching shows on Netflix when all of a sudden my screen gets a weird green tint. I didn't touch the computer. It just happened all of a sudden. I tried updating my graphics card driver and Windows to fix the problem but it didn't work. I also tried restarting, system restoring, and starting in safe mode and the green tint doesn't go away. On top of that, the screen will leave a light after-image of previous windows on black parts of the screen. I'm assuming it's a hardware issue, but I wanted to check and see if there was anything else I could do to make sure it isn't a software issue that I can fix on my own. Just sending the machine in for repairs costs $200+ USD and I really don't want to do that. Especially considering I had just sent this machine in for an RMA like 3 months ago for a different problem.

 

 

I've attached 2 photos so you can see what I'm talking about. I took them with my phone instead of a screenshot because I figured the color distortion wouldn't show with a screenshot.

 

I also don't know if this means anything, but under Device Manager > Monitor > Properties > Events, this was there:

Device DISPLAY\LGD046C\5&3a12d022&2&UID4353 was not migrated due to partial or ambiguous match.

If there's any other information I need to provide please let me know. Thanks.

If reinstalling the graphics driver does not help I would have to hazard a guess your graphics card/chipset has failed. I have the same issue on an old XP computer with a Geforce card. Changed monitors and still had the green tint. This indicates you have lost the red and or blue. There is not much you can do other than use the computer as is, get it fixed, or purchase a new computer. 

 

This computer has two chipsets for graphics, Intel and Nvidia?

I think I've definitely lost the red because a lot of red things on my screen are greyed out. Yeah I did do a clean installation of the Nvidia driver when I updated :(

 

I'm not sure about Intel. When I open device manager only Nvidia shows up under Display Adapters. Or would the Intel one show up somewhere else?

I was looking at the Sager support site but only found NP8172 and saw device drivers for both intel and nvidia. I could not find the support page for NP8172-S. If you can find the support site for this version look at the specs to determine if the computer came with two chipsets. Your BIOS may show both chipsets if you have two.

Yeah I can't find the support page for S either. I checked my BIOS and I didn't find an Intel chipset.

The Clevo number you posted only shows the nvidia chipset.

Damn. So it turns out to be a hardware issue after all?

I would say yes, it is a hardware problem. When you boot to your BIOS screen you still have the green tint, correct? If you want to confirm it you can boot a live linux disk and if you get this tinted screen through the boot process then your graphics chipset is bad.

Yeah I still have the green tint in BIOS screen. Welp, that sucks. Would the GPU also be the culprit for the ghosting? It happened soon after the green thing happened.

Yes, I believe that the ghosting is also GPU related, sorry. You may be able to get the screen somewhat readable but still with the tint by changing the color settings like Gamma for each color in the dropdown box in the Nvidia Control Panel settings.

Thanks. I did this and it looks a little better than before. It's a shame about the card though. I guess I learned to stay away from Sager and XoticPC the hard way.

no said anything about cables, did you unplug video cables and plug back in making sure they are snug?   usually a loose cable will do what your pictures are doings

Being a laptop I think the chances of a loose display cable are slim but possible. I could not find a teardown guide for the above Sager model. The closest I could find was a video of the NP8561. The cable connection to the display is about 3:30 into the video. The connection to the MB would require almost a complete teardown.

 

Edit: The one thing I forgot was to try an external monitor and see if the tint was present.
