Total tests:
- 3840x2160 60Hz, the image is not transmitted, black screen.
- 3840x2160 30Hz, the picture jumps, is unstable, it is unusable.
- 2560x1440 60Hz, the image trembles slightly from left to right intermittently, it's tiring after a while.
This is clearly not a suitable cable or for troubleshooting.
Pity.
