How do I set the monitor to 75hz?

Following question:

I own a AOC G2460V with 75hz. Unfortunately I can't use this frequency.

Why is that?

The monitor is connected to my notebook with a HDMI Ultra.

CPU: 0I5 7200u

RAM: 8G

GPU: Intel HD 620+ (AMD Radeon R7 m340)

One knows to my knowledge no higher frequency than 60Hz in the Intel driver to select, whether in-game is possible (then the Radeon map should be active).

I can also select only 60hz in games.

Times this in the Radeon setting to change?

And / or sometimes about the Intel graphics setting to change.

Try right-clicking on the desktop Display Settings → Advanced Display Settings → Adapter Properties → List All Modes

There you can be sure that all available modes are listed. If there are no 75Hz available, your notebook may not have HDMI-Ultra output. Also with HDMI connections there are different models or generations.

I checked. You're right. My notebook only supports 1080p with 60hz.

My Radeon card only turns on in games. I have already looked after and have found that my HDMI Beech only 1920: 1080 with 60hz can give again.

Because 1.4?

That's a pity.

Ahh well then my question is superfluous above.
