Pick the cheapest with most stars on Amazon. They are for a digital signal. Either they work or they don't. There isn't much quality to look out for. Maybe if you move it around a lot you'd want something robust.
But it won't deliver a worse image if you buy cheap.
Just because it's a digital signal doesn't mean "it works or it doesn't". If the cable you chose can't handle the bandwidth necessary for the audio and video signals you're trying to push through your equipment will automatically start degrading the signal slightly to maintain sync and connection. This will start with white clipping and black crush and will get worse from there.
Truly shitty cables will often have DHCP and AV sync problems.
DHCP problems, huh?
Oops. HDCP
If you don't get signal in however long the TTL is, your lease expires.
I generally agree except I try not to shop Amazon. For stuff like this, monoprice is my jam.
If you are in the US. I see they do shipping outside of the US but that will supposedly make you pay extra taxes for the import.
Good point.
Well, if you ARE in the US, here's a sample 2.1 cable for $5
I mean, not in OPβs particular application, but in industrial applications you donβt want to pick the cheapest:
-How does the cable fare against EMI? -What is the maximum possible length? There is even an optical HDMI cable to help with this -Will the cable need to be resistant to rubbing?
Etc, etc
Yep. In industrial settings, including distribution and sortation facilities for all the packages that reach your door, a broken wire can mean downtime and a bunch of lost money every minute.
The engineers not only specify the exact quality of wire/cable that must be used, but often put that inside rigid steel conduit and limit where it can be run, all to protect the wire. And thatβs before you get into redundant routes for the really important stuff, which could even use a different type of cable like fiber.
