Gamma calibration Windows vs browser

[DSD27]

I have gamma perfectly calibrated through Windows Calibration tool. But every gamma calibrating website, with test images, say that I have around 1.9 to 2.1 gamma.

Does this mean that my monitor a gamma different from 2.2, Windows automatically detects that and sets the calibration tool to match it? Or there is a problem with the browsers?

The monitor is Asus VG27WQ.

For a much better explanation than what I can supply, read this article:

where they explain, with excellent photos, the differences between the varying levels.

It doesn't explain why Windows calibration tool says mine is perfect at default, while the websites say it's too low.

It's the median figure derived from testing over a wide range of monitors. It just that they had to account for every monitor produced, to come up with a figure that would work across the board, and their chart uses that figure.

It does not necessarily, reflect the true gamma of any screen, its just a chart that will work with every screen produced.

 

For a good way of seeing what I'm trying to explain, look at the television screens on the wall at your local Walmart. All of those screens are set to their default settings. Note the differences?

So the conclusion is that it doesn't work with mine?

2.2 is default for LCD monitors.

This should also work with Windows 11. or you can do it through the monitors menu, if possible or the software that came with the monitor itself, you may be able to get this from your monitors manufacturers website, again, if they have one.

Exactly how I did it. Perfect on Windows, but on that website, the square that blends with the background is 2.0.

To get 2.2,, I need to lower the slider a little bit, the white dots start showing up slightly, in the middle of the circles.

When you're   n the site go into your monitor settings and adjust the contrast as needed. This sometimes needs adjusting because there are slight differences even between the same make and model.
