Although it is not a well-known brand, it has very good build quality.
It is HDMI 2.0b version (https://greencell.global/en/cable-hdmi/4050-cable-green-cell-gc-streamplay-hdmi-hdmi-20b-5m-with-4k-60-hz-support.html#specification).
It has been tested on screens with 1080p and 1440p resolution and has no issues (disconnections, etc.).
It will be tested later on a 4K monitor and TV and I will update.
Also, because it is Braided, it stays in place without changing its shape.
The price for €10 is very good.

Although it is NOT a certified HDMI cable (https://hdmi.org/spec/premiumcable), after about 1.5 years, it still works flawlessly (no sudden disconnections, pixelation, etc.) in all resolutions (4K, QHD, FHD) at 60 Hz (tested at this frequency), although the cable supports higher frequencies in some resolutions (QHD, FHD).

It was used to connect a computer to a 4K TV. It supports a full 18Gbps connection without interruptions. It seems quite high-quality. I am very satisfied with the €10 price for a 5m cable.

Very good quality! It has not disconnected on me at all! Impeccable image quality! It is worth its money

Expensive, but here you get what you pay for.
Connected the TV with an amplifier and the Nvidia shield. With the cheaper cables (equip, savio, etc.) and even though they claimed to support hdmi 2.0, 4k60Hz, I experienced frequent interruptions of 1-2 seconds, as well as HDCP errors. After ruling out any damage to the devices, I changed the cables and the problem disappeared.

The cables are thick but still quite flexible and "lock" into the shape you give them.

VFM Cable. Transfers image and sound seamlessly without interruptions! It is of type 2.0b, so it can handle high frequencies HZ (120HZ), if your devices support it.
