Blue tint to Screen

[Amelia Weavers]

I had a gtx 560 in my computer and I needed an upgrade so I bought and installed a gtx 960. My computer was plugged into my tv through the vga port and worked fine. After installing the graphics card, the screen had a purple tint to it. I assumed installing the latest drivers would make the tint go away. I was right I guess, the purple tint went away and instead was replaced by a dark blue tint. I thought it was the cord, so I plugged the computer into my old monitor and it worked fine. I then thought it was the port on my tv so I plugged my girlfriends laptop into my tv using the same cord and it displayed fine. I tried adjusting the color setting on my tv and messed around with the settings on the nvidia control panel, but it had no effect and I guess I didn't see the point when it displayed fine with the other monitors. So any help would be greatly appreciated as going from a 42 in screen to an 18 is slightly painful. Also I should add, while I built this computer I have no idea what I'm doing and have been banging my head against the problem for a couple hours now. Thanks for your time.

Well, if it is the cord, moving it from one machine to another for testing could have corrected the problem momentarily. Have you tried adjusting the signal cable, flexing, or jostling it anywhere that it bends from the gravitational stresses of being attached in a given orientation for a prolonged period of time? It is not unheard of for analog VGA cables to have the Red, Green, Blue, or even a combination of the three to start going bad. This usually results in exactly what you describe, to varying degrees. The best test would be to completely replace the cable with one that is known to be in working condition.

Of course, if you can't determine the cause, adjusting the color of the screen or using a color profile that is adjusted to compensate may at least get you back to what you feel the color representation should be.

So after messing with the cable, I gave up and decided that I would just plug my older monitor in and would use that for the time being. The screen on that was also dark blue so I figured it was in fact the cable that was bad. I ran to best buy and the guy told me it would be easier to get a dvi-d to a hdmi cable and plug the tv in that way. I got the cable and plugged it in and everything looked good. The tint was gone and the starting windows screen displayed. The new problem is that after getting past the starting windows screen my tv displayed no signal and wouldn't display my desktop. It still played the windows chime as if it logged on but didn't give me any picture. I restarted windows and went into safemode and it logged on and displayed the desktop fine. I thought reinstalling the driver that came on the cd with the graphics card might help so I installed it, but that didn't help anything. My next idea was installing the latest drivers might help, but the site wouldn't let me because I was in safe mode. Any ideas on how I might be able to fix this new issue? Thanks again for your time. I figured this process would be a pain but wow.

If your screen is displaying "No Signal" then you have your desktop settings set to something the screen does not support. Make sure you aren't trying to feed the TV with a non-standard refresh rate. Standard would be a multiple of 60 Hz, and most likely unless it's an expensive set, no more than 60. While you may have been able to send more when using your analog cable, that is likely due to the analog circuitry of the TV automatically scaling back the refresh rate. The digital circuitry is far simpler and as a result will often times just give up when faced with a non-conforming signal.

You mention installing drivers from your CD that came with your graphics card. The drivers on the pack-in disc are usually outdated before you even break the seal on the package. While they usually work to get you going, they are not considered the best to use. Using the most up-to-date drivers should yield the highest stability, feature exposure, and performance for your card.

I had this problem -- Windows 7 laptop connected to external monitor with blue tint. Turned out it was just that the VGA cable was loose. I tightened the knobs on the VGA cable and monitor is back to normal.
