Why does it give a black screen at 120/144 HZ?

Question

Samsung

Everything is ok at 60 HZ, video card Nvidia Geforce GTX 1060 6GB, driver 472.12 09/20/2021
OS - Windows 10
Monitor - Samsung Odyssey G7 driver 10010.9
HDMI 2.0 cable checked, whole, sits tightly in the sockets.
I know the limits

spoiler

Nowadays, most monitors, TVs and graphics cards feature at least an HDMI 1.4 port which is enough for 144Hz at 1080p, 75Hz at 1440p and 30Hz at 4K.

However, keep in mind that some monitors have limited bandwidth over HDMI 1.4 making it max out at 120Hz or even at 60Hz in some cases (mostly G-SYNC and older monitors).

In fact, most 144Hz monitors are limited to 120Hz over HDMI 1.4, but some monitor manufacturers will utilize custom timing parameters, pixel rates, etc to use the full potential of the HDMI 1.4 bandwidth, thus getting 144Hz at 1080p.

So, make sure the exact monitor you’re looking at supports 144Hz or at least 120Hz over its HDMI 1.4 port — or just look for a 144Hz display with HDMI 2.0.

HDMI 2.0 is also fairly standard and can be used for 240Hz at 1080p, 144Hz at 1440p and 60Hz at 4K. The latest HDMI 2.1 adds native support for 120Hz at 4K UHD and 60Hz at 8K.

So that the specification satisfies the requirements

Model C32G75T
Video Inputs 2x DisplayPort 1.4
1x HDMI 2.0

I think there is a LOC somewhere, be it in nvidia or windows.
Tried to change HZ in Nvidia Control Setting, Display -> Advanced Display Settings -> Monitor -> Screen Refresh rate

HDMI 2.0 supports 144 Hz for 2560 × 1440 (16:9)

Missing G-sync config for 1060 although should be
