Display Problem - green/blue tint

Hi, I'm trying to figure out if my monitor is not working or if it is my video card or both. My monitor has a green/blue tint to it and I can't see the color red, but if I bring up the settings I can see red, though changing/resetting the color settings doesn't do anything for the actual display.

Here's a photo to make it easier to understand: http://mikaristar.deviantart.com/art/Monitor-638482316 The candy corn on the wallpaper (left) is supposed to be orange, the right image shows the settings in default after resetting the monitor (the actual monitor, not just the PC). I've also tried rebooting the PC but nothing changes. The fact that I can see red on the settings is what makes me wonder if it really is the monitor, since it's at least capable of displaying the color there... Any ideas?

The card is an Nvidia with 2 ports, the monitor is connected through an adapter (It doesn't fit directly). I've had this set up for a few years now.
 
All you can do is try the monitor on a different pc to see what happens. Since the settings display the color red we can probably assume its something with the cable connection or video card.
 
It's probably your monitor. The colours are made up using just three colours. Red, blue and green. You have lost red. The bit of your monitor that drives the red LEDs has gone phut. As suggested try another monitor.
 
Update: The monitor won't display anything, though the light flashes as if it were disconnected. Here's a photo of the adapter: http://mikaristar.deviantart.com/art/Adapter-638494543 I thought about trying it out with the motherboard output but it also doesn't work, although maybe that's because NVidia is in there.

I'm thinking about getting a new cable, maybe I can find one that doesn't need an adapter... I don't have any spares to test with though.
 
Okay it's been a long time since I did any technical stuff with tellys and monitors and then it was with CRT type things so this answer is not definitive or even neccessarily correct. (Nice nails by the way) Anyway the blue plug is an VGA plug and the pins look okay in that. The grey plug is a DVI plug, presumably your VGA to DVI adaptor and that looks okay. In the days that I was doing this stuff if a monitor/ television had a red/blue/green cast to it's picture then drive input to that particular colour had been lost. That would be from the previous board, in your case your graphics card or the cable. If, as in your case, there was no red/blue/green then that was because the circuitry that supplied the feed to the red/blue/green guns or LEDs had failed. Now that would mean that in your case the fault is in the monitor. Having said that monitors are expensive and monitor leads are cheap so I would go for the lead first. The other thing it could be is your graphics card. I am assuming that this is a desktop rather than a laptop. If so then the card is mounted horizontally on the motherboard. Over a period of time the weight of the board will pull said board down and the connections can fail. I do not know how capable you are with this sort of stuff but I would take the side off the computer and unplug the graphics card and plug it back in. It can effect other cards that hang off the motherboard as well such as the RAM modules etc. If you do decide to go into your computer make sure it is switched off and the mains power plug is removed from the back of the computer.

Wow... You really don't understand how monitors work, do you? There are no colored LEDs. Monitors have a white backlight and the colors are made up by LCD pixels. There is no such thing as an "LED" display. That is a misconception. There are LCD monitors with conventional (fluorescent) and LED (light emitting diode) backlights. That is all.
 
I've poked around in the computer before, Nvidia is tightly in place.

From what I've gathered at various forums, it looks like changing the cable might be the way to go. I bought a new cable before work, but I won't be able to test it until the end of the day. Let's see how that goes. I hope the problem is finally solved, I'll post the results later.

You knew exactly what I was trying to say and there was absolutely no need for you to come on here ranting and raving about me not knowing how things work. I do know how things work and whilst you are correct the pruinciple is the same. If you had taken the time to read my original post I freely admitted that I hadn't done this sort of stuff for a lot of years since CRT days in fact. The principles of what I said are correct. I bet you are going to vote for Trump as well.

Well sorry mikari I'm out of here youi will have get any help from the others like mistersprinkles. Good luck with that.
 
I live in Canada. If I lived in the USA I would not vote for Trump.
I voted for the NDP party here in Canada last year. They lost. Justin Trudeau won. I'm glad he did. Cool guy. He's legalizing pot.
 
Unrelated politics aside, the new cable worked for a little while, one power outage later and this is what's happening now:


I think it's time to give up. :( Thanks to everyone who took the time to reply, any final thoughts?
 
Keep it on topic guys and try to be civil. If you want to argue about politics take it to a PM.

Power outage? That's likely a different issue entirely then.
 
Yeah, the electricity came back for a while, which is when I took the video, but it went out again. Unstable electricity is annoyingly common, which is why I'm considering sticking to laptops only in the future, despite the fact that I really like gaming PCs.
 
Then you need to invest in an apc/battery backup. They provide clean power and also when power does go out then it gives you a certain amount of time frame to do what you need to do and turn your system off before battery runs out juice.
 
I had one... it died... Any recs on a brand of battery/surge protector that can actually take a hit? I'm looking into getting protection devices for everything, including cell phone recharging, PSVita, etc. because it's clear the electrical problems aren't going anywhere (the whole neighborhood has had unstable electricity lately).
