Making a custom HDMI cable with these parts is super easy. First, get your hands on the 10 cm HDMI ribbon cable. Then, choose the two HDMI adapters you like from our shop (the adapters aren't included with the cable). Use the flex cable clips to attach the adapters to each end of the cable. You can mix and match different adapters to suit your needs. When using the cable, keep in mind that it's not as tough or well - protected as ready - made cables. So, be gentle when handling it to avoid damage. As for maintenance, just keep it clean and away from sharp objects. If you're using it with a Raspberry Pi or other devices, it should work well at 1080P as we've tested. But if you notice any issues, check the connections first.
