Hey,
So just a quick question I wanted to run by everyone here.

I’ve been lead to believe for years that an expensive cable (we shall say HDMI in this case for the sake of it) performs to exactly the same ability of that of a cheap HDMI at only a couple of dollars.

However I’ve also heard that if your cable becomes longer, say you wanted a 3m HDMI cable then in this instance a slightly more expensive better quality cable performs better.

So is there truth behind all this, I’m still fairly convinced that on short distances the quality of the cable makes no difference though I’d always opt for something made half decent and not the cheapest thing on the market.
But if I wanted to run a longer cable should I be investing a bit more cash in a better quality cable to not sacrifice on performance?

It’s not necessarily the price you should judge HDMI cables by. There are HDMI standards that a cable certified for that standard must meet.

If your video and audio source can produce all new bells and whistles, and your screen can utilize all those new top end features as well...you will need to make sure your HDMI cable can also deliver those features. You do that by determining what HDMI standard the cable meets.

The latest standard is HDMI 2.1 out just a year now, but just beginning to have new electronics in marketplace that can utilize or will need the enhanced bandwidth and features it can transfer. HDMI cables certified 2.1 should support much higher video bandwidths and refresh rates up to 48 gbps and from 4K up to future10k video, enhanced HDR, new eARC audio features, and new Varriable Refresh Rate (VRR) computer graphics. Evidently the brand new nVidia driver v417.71 launches nVidia support for VRR on some GTX 1000 series cards and RTX 2000 series cards using a single G-Sync capable monitor...( v417.71 driver loaded up on my old rig just today...lol..but I don’t have cards nor monitors yet supporting G-Synch or VRR )

The previous 2015-2016 HDMI 2.0a or b cable standards don’t include compatibility with many of those new 2018-2019 new features, and those cables were only certified up to 18 gbps bandwidth...enough for basic 4K HDR....but some newer features may not be compatible...may not work right for you on newer 2018-2019 gear.

Like he. HockeyBuck, said.
Be careful with the branding of HDMI cables and only buy from reputable companies. Big%20Smile

Most of this debate that I’ve seen involves Monster cable vs everyone else.    Monster is obscenely expensive, it’s marketing catering to the people that want bragging rights, bling effect, etc.    

That said, Monster has been shown to be a bit better in very long runs, which most don’t use.   Or if you’re a musician or pc competitor that is constantly moving your equipment around, the added durability will help with wear on the connections.   

A Walmart or Cables to Go pick , assuming you use a certified cable for your bandwidth, are just as good, any difference being unnoticeable.    Of course there will always be exceptions.

Thanks for the feedback. The two cables I need to robsly be a bit longer are the HDMI and the dp cables, both reach my pc fine at the minute, though with how I now have my cable management set up they are not gonna reach my new pc when I get it, so I’m gonna need some longer ones, as for usb inputs such as keyboard, wheel pedals, track ir etc I’m thinking of just running a four port usb hub from my pc under the desk until it reaches the usb cables, should work shouldn’t it? Or does connecting usb items like a wheel and keyboard or even track ir to your pc via an additional hub cause connection issues or lag?

For the cables I’m only talking like maybe 2 meters here but I haven’t measured it yet to be exact
