My understanding is that the data rates have gone up to handle current high end 4K and future 8K formats. The bandwidth spec has gone from like 9Gbps to 18 and now 54. And length can make a difference if you're running long cables, say for a projector over a 25-40' cable. For typical 2M length cables it's less important.

But if you are doing 4K at 120Hz frame rates (which only exists in games right now) or at some point 8K, you'll need the cables that can pass a much higher data rate, and the 10 year old cables might not handle it.

The connections from one end to another on an HDMI cable do not change because of a change in HDMI protocols. Those are hardware-based changes on the RX and RV ends. HDmI is a "Licensed Standard" and products, such as BluRay players, TV's, and Media Players pay a licensing fee to the HDMI organization to be able to even say they are HDMI compatible, whichever version they are. The connection interface on each device is what is licensed for the various iterations, not the cable, UNLESS you want to state that in your advertisement, in which case, you send your cable to HDMI, they test it, it passes, your approved and now you pay them a licensing fee to say you're a high speed cable.

Think of it like a road and a high performance car. The road may have been designed to travel at 70 mph, but you can for sure take a high performance car and drive at 120 on it if you want to, but it's not the best way to do it. For that you go to a track. Same with cables. You can use them and generally it's fine, but when you get a lot of cables and electrical and magnetic subs all in a close space, that older cable "should" work, but the high performance cable is the safest way to go.

Depends on the reason for retiring them, if they were still functional save them for a worst-case scenario, if they are acting wonky it's probably a terminal malfunction so chunk em!

Serious HDMI talk here. I dig it.

Trying to run an HDMI from a receiver in the house out to a Patio TV and looking at 100 ft active HDMI cables. I've seen great and terrible reviews about runs that long. But "active" HDMI is supposed to have a chip to boost the signal strength for that length run...

Is that true? And can I buy a $100 HDMI off Amazon (Monoprice for example)? Or go with Crutchfield's $350 version (Metra InstallBay)?

I've had a couple of generations of 50 ft cables from Monoprice for my projection setup. Last one I bought was a "Luxe" series which I see is still offered. MP is where I would look.

I'd look at 18Gbps rated cables as 100 ft is pretty long - but check the specific length spec as some of them are 18Gbps at lower lengths but not at 100'.

Any benefit to running network cable through an extender?

Good info in this thread!

I will be upgrading to LG CX OLED in next few months. I'll need ~35 ft HDMI run (and it will be in wall, so I assume in-wall rated is necessary). I'm looking at these cables from monoprice. I assume these would be sufficient for my needs, but looking for confirmation from more knowledgable people in this thread.

Thanks

CL3 is overkill for this vs CL2. I'd save a few $ and get this cable:

Chunk 'em. They are all cheap enough now to not justify the storage space.
