Windows 10: monitor will not display the color yellow

At some point, my computer stopped displaying the color yellow. Instead, I get green for any and all applications, work, whatever. Putting in the rgb values for pure yellow and green brings up almost identical colors the yellow has a slightly yellowish tinge to intense green. All drivers are up-to-date and any system check or diagnostic test of the computer shows everything is working fine and/or "healthy". I use 2 monitors and both have the same problem so it is not a monitor issue. In fact, I have no other problems with the computer but this strange aggravation. For one day after a Windows update I use 10 Pro, 64-bit, yellow was displayed until the computer got rebooted. Everyone I talk to about this just scratches their head. Any suggestions will be very much appreciated.

Color Calibration of two Dell U2415 monitors - both too yellow?

I just received two Dell UltraSharp 24 U2415 monitors, which proudly boast "Award winning monitor with unbeatable color".

I am hooking these two up to a single laptop, an ASUS GL551K running Windows 10. One of them is via the provided Mini DisplayPort cable, the other through an HDMI cable to HDMI input on the monitor.

The problem is they both look bad. The whites are yellow, and as someone who stares at a sea of code all day, none of the colors look familiar.

They look fine on the laptop, nice bright whites, but both of the Dells are no good. I hooked it up to a Mac and it looks a lot better on that side.

To make a long story short, I have tried all of the following, and am unable to get a pure "white" color on either of these two monitors:

• Use in-monitor menu system to reset every option back to "factory defaults"
  
• Went into Color Calibration in Windows 10 and remove any pre-set profiles there, whether my own or Dell's
  
  • Ran monitor calibration, and it looks fine for gamma, contrast, and gray
    
  • Manually adjusted the RGB sliders to attempt to get a whiter white, but as close as I can get, it is not white. It looks like faded paper.
    

I highly doubt that I could get delivered two top-selling 24" monitors and both of them have a problem, so I'd just like to know how to adjust this. I went through other tutorials step-by-step, and so far, no luck.

I understand there are a whole host of "taking a photo of screens" when it comes to color calibration, but this is what I see ... close enough, anyway:





Thanks!

 

Windows Color Management Issue

Hi billin30,

With the issue you're having with your display color, I suggest that you calibrate. There may have been settings that is causing the issue and resetting them may solve this. Follow these steps:

1. Press Windows key on your keyboard, type Calibrate display color.
2. Follow the on screen instructions.

If the issue will not somehow improve, try to check with your monitor's color settings just to be sure.

Also, I'd like to clarify what monitor is having the issue with its display going to the 'other monitor'? I'd also like to ask for help in isolating the issue. Try to use the monitors one-by-one or have them pair up with one another. Like have BenQ paired
with Asus then have Alienware paired with Asus etc.

Update me if there were improvements.

 

lost red color on my computer monitor

Hi Yanjun,

Color calibration is something the operating system can't accurately do automatically. To make sure that your monitor is set to display the most accurate colors, you may use the built-in Display Color Calibration utility. Here's how:

• Go to Settings > System > Display.
  
• Scroll down to the very bottom, then click Display adapter properties.
• Select the Color Management tab, then click Color Management (...).
• Select the Advanced tab then click Calibrate display.
• This will start the Display Color Calibration wizard. If you are new to calibrating your monitor’s color, click the
  How do I calibrate my display? link for more information.
• Click Next to begin adjustment.
• The wizard will now walk you through the steps to access the on-screen display menu on your monitor to set specific color settings.
  

Remember that changes made through the display menu will be kept even if you click
Cancel. However, if you're not happy with the new settings, you can revert the changes manually, or reset your display to the default settings.

Let us know how it goes.
