HDMI cables suck for 4K beyond 25 feet I'm finding out...

The official MS HDMI cable that comes with the One S will do 4K @ 60Hz (6.5ft length) perfectly fine I think. Once you get beyond 20 feet or maybe even 15 feet a lot of cables start to poop out. There are tons of very long (25 feet +), very highly rated,
supposedly high speed (up to 18Gbps) cables on Amazon that claim to do 4K @60Hz. They don't. They're highly rated because so many people (probably 95%) are using them for 1080p, and they work just fine for that. But more and more 4K reviewers are starting
to give these longer cables 1-star reviews. People are even complaining that Redmere "active" cables (that are 1-way directional) are failing for 4K.

A few people on the AVSforum like this one:

Certified Premium High Speed HDMI® Cable, 20ft

...but it's only 20 feet. I'd like a 35 foot cable for a home theater room. For now, I'm forced to have the One S in a game room next to the TV. The monoprice cable has an HDMI.org certification so it probably really does what it says it can do...

XBF Brad A, XBF Crystal P, and Wrightstuff1,

Thank you for your suggestions but it didn’t solve the problem.

I took a guess and replaced the 25 feet HDMI cable from my receiver to the TV. Problem was solved.

I bought a new HDMI 25 ft cable and replaced the 10 year old 25 ft HDMI cable. The new HDMI cable that I bought was a Monoprice Certified Premium High Speed HDMI Cable. Now even my Blu Ray discs play on the Xbox One. 4k and regular DVDs also play using
that new HDMI cable.

The mystery though on my original problem is why the 4K discs played and not the Blu Ray. I would think that the 4K discs would not play and Blu Ray would play.

Anyway, with the new certified 25 ft cable, all is well.

With the amount of (4K) bandwidth that gets transferred over HDMI, you're definitely pushing the limit at 50 feet. There's no established cable limit for HDMI, but there are reports that the maximum reliable signal goes around your 50 feet (~15m), using
the absolutely best quality cables.

Attenuation (or weakening) of the electrical signal over that length of HDMI cable is causing it to not display anything. As HDMI is a digital signal, you will either get a perfect signal, or nothing at all.

You will have to consider getting an active HDMI repeater to extend the signal between those 50 feet, ensuring it supports driving 4K@60Hz.

It's a tall order to support this kind of 4K setup. Have you considered moving the Xbox closer to the TV? lol.

Typically you dont want anything longer then 25 meters realistically 10 feet is optimal before signal degration

Also should be noted not all 4k cables are hdr compliant as I found out

See the way you are desscribe your setup

Xbox to hdmi to hdmi extender to hdmi adapter to vga cable to monitor

Thats alot.of.devices

What it should.be is xbox to hdmi to adapter to.vga to.monitor

So.why arent you moving your xbox closer to yoir monitor

AmazonBasics DVI to HDMI Cable 25 feet (7.6 meters) https://www.amazon.ca/dp/B014I8V0EO/ref=cm_sw_r_cp_apa_i_rmpqDbJBVBVP1

This is aboit 25.feet and only needs one cable.direct.from.your console to your monitor unless you have some odd reason not to have your xbox next to your monitor or nearby
