How do I fix minor gamma effect

Hello Pyx - ,

Thank you for posting in Microsoft Community.

We understand that you're experiencing gamma glitches on your Xbox Series X, and Xbox One games. Let us check on this together and sort this out in timely manner.

May we know what is make and model of the TV?

Here are some steps you can try to fix the issue:



1. Check your TV or monitor settings: Make sure that your TV or monitor is set to the correct display mode and that the gamma settings are not too high or too low.



2. Check your Xbox display settings: Go to Settings > General > TV & display options > Video modes and make sure that your display settings are set to the correct resolution and refresh rate.



3. Update your Xbox: Make sure that your Xbox is up to date with the latest software updates. You can check for updates by going to Settings > System > Updates & downloads.



4. Reset your Xbox display settings: Go to Settings > General > TV & display options > Video fidelity & overscan and select "Reset display settings."



If none of these steps work, you may want to try using different TV or monitor to test if this issue is isolated.

We look forward to your response. Kindly let us know, if there is any misunderstanding or clarifications of our description by sending us a reply.

Sincerely,

To add salt to the wound. The gamma curve is still skewed on the Xbox One S. I wonder how MS wants to do HDR with an incorrect gamma curve.

Yes, RGB+Expanded gives full range.

I'm unsure of what the default output gamma curve is on the Xbox 360, but games can differ quite a lot in how they approach gamma. The output gamma ramp is possibly set using a proper lookup table instead of a piece-wise linear approximation as used in the
sRGB to linear conversion in rendering.

What is the "right" display gamma is quite debated, but on CRT broadcast monitors it's been estimated to be around the 2.2 - 2.5 range if I remember correctly (ITU specifies an assumed average display gamma of 2.35). The effective encoded gamma in the BT.709
standard is around 1÷1.97, but in practice it still assumes that the display gamma is higher.

The best gamma curve is very dependent on viewing conditions. 1.9 would likely give too bright midtones, and I'd shoot for 2.2 - 2.5 instead. The 10-point gamma adjustment is only useful for calibration, to ensure that the curve is as smooth as possible.
It requires a calibration tool and software to be useful.

Gamma curve skewed? This is the final straw M.S.! Will now sell my basement full of X Box One consoles and "invest" in something else...
