How to fix Samsung QN85B and QN90B inaccurate color issues

When watching videos and/or playing games on your Samsung QN85B or QN90B Neo QLED 4K TV, you may notice that the colors may look off.

You can take a look at this troubleshooting article from Seeking Tech to see how you can potentially fix inaccurate display colors with both of these television sets.

Before we begin, it should be noted that this guide is going to be based on the following model numbers:

  • 55” Samsung QN85B Neo QLED (QN55QN85BAFXZA)
  • 65” Samsung QN85B Neo QLED (QN65QN85BAFXZA)
  • 75” Samsung QN85B Neo QLED (QN75QN85BAFXZA)
  • 85” Samsung QN85B Neo QLED (QN85QN85BAFXZA)
  • 55” Samsung QN90B Neo QLED (QN55QN90BAFXZA)
  • 65” Samsung QN90B Neo QLED (QN65QN90BAFXZA)
  • 75” Samsung QN90B Neo QLED (QN75QN90BAFXZA)
  • 85” Samsung QN90B Neo QLED (QN85QN90BAFXZA)

1. The first step you can take is to try resetting the picture settings.

In order to do so, you need to press the home button on the remote controller and then head to Menu > Settings > All Settings > Picture > Expert Settings > Reset Picture.

2. You can also try disabling the Brightness Optimization setting by first pressing the home button on the QN85B or QN90B remote and then selecting Menu > Settings > All Settings > General & Privacy > Power and Energy Saving > Brightness Optimization.

Afterwards, make sure that Brightness Optimization is currently turned off.

3. We also recommend that you disable Brightness Reduction, which you can do by pressing the home button on the remote and then going to Menu > Settings > All Settings > General & Privacy > Power and Energy Saving > Brightness Reduction.

You should then make sure that Brightness Reduction is turned off.

4. If the colors still do not look right, then you may want to change the picture mode of your Samsung QN85B or QN90B.

In order to do so, you need to press the home button and then go to Menu > Settings > All Settings > Picture > Picture Mode.

5. You can also try manually adjusting several expert picture settings.

To do so, you need to press the home button on the remote and then head to Menu > Settings > All Settings > Picture > Expert Settings.

You can then try changing the following from the Expert Settings menu in order to get more accurate colors:

  • Contrast
  • Brightness
  • Sharpness
  • Color
  • Tint (G/R)

6. We also suggest that you perform a picture test by first pressing the home button on the remote control and then going to Menu > Settings > Support > Device Care > Self Diagnosis Picture Test.

If the test shows that there is nothing wrong with your QN85B or QN90B screen, then the inaccurate colors may be caused by the device that is connected to your TV.

In this case, you should refer to the instruction’s manual of the connected device to see what you can do in order to get better colors.
