Fiber Optic HDMI VS Copper HDMI (DEMO/REVIEW)

In this video, I compare the performance of a Ruipro fiber optic HDMI cable against a generic copper HDMI cable. To capture this comparison, I am using a Sony X800 4K Blu Ray player and the 4K movie Aquaman. The footage is being captured with both HDMI cables on my LG CX television using the 4K GoPro Hero 8 camera.

The settings on the TV, blu ray player and camera are exactly the same for both HDMI cables to ensure a fair video comparison. After the video comparison, I offer my thoughts on the comparison and whether or not you should buy an expensive fiber optic HDMI cable for your source and TV.

They make a difference over long runs of 16 ft plus.

I thought this video was very informative and the host honest in the information he was presenting. I used the information given in this video to make my final decision concerning which HDMI cable to purchase for my new 65" LG television. Thank you for your honesty and the visual comparison you demonstrated to illustrate your findings and opinion. Thank you again and God Bless. Paul M.

Interestingly, I did an A/B test on my non HDR projector in my cinema room. There is a difference in contrast and the motion blur improved, but its was ever so subtle. I would say the upgrade is worth it, but don't go crazy and overpay for cables. I would say your cable is pretty spot on and the video is great! You helped me chose my fibre optic cable :)

This may have already been said but my understanding regarding Fiber Optic HDMI is that it differentiates itself from traditional copper HDMI after 10 -12 feet? Anything less than that will look/sound identical?

Digital signals are as much subject to outside influence as is analogue signals. EMI and other outside factors can cause bit flipping, attenuation, cross talk, jitter, noise, impulse noise, echo or signal reflections, phase shift etc.. In digital there is error correction crc/tmds etc., these can detect corrupted data/bit flips etc. and ask for the signal to be resent, while data buffers can minimize jitter. But jitter is the main concern in digital data transfer. Optical cables are not subject to emi interference, and have no jitter but can have modal dispersion in multimode fibers, not single mode fibers used in hdmi and usb. A good quality cable matters, and optical is likely best even with the laser diode conversion of the signal, which is 1 to 1, there is no loss or errors.

This is a very well done comparison, the factor that convinced me to use fiber is immunity to electromagnetic interference. Thanks

Hi. Will 7 meters optical HDMI cable work with sound between my TV and PC using Mini DisplayPort to HDMI adapter? My Graphic Card outputs sound BTW. Thank you.

[peaceseeker]

Does audio signal travels both ways through fibre hdmi??I want to connect my tv box to the hdmi in of the dolby atmos soundbar and the hdmi out(earc) to the arc port of the projector...but i want to know that if i connect ps5 or pc to projector, will i get the dolby atmos sound from my soundbar if i connect my soundbar and projector with fibre hdmi???does the source and target thing works with only video signals or with audio signals too??

I’d like to see the same test over a long cable run like 30 feet or more. Rumor is that’s where cooper develops degradation and fiber is claimed to be unaffected.

[blake_]

Distance between my Xbox and tv roughly 2metres should I use fibre optic hdmi, is it better image quality?

[ernieschatz]

You WILL experience attenuation and image degradation over longer runs of copper HDMI cable. That's really how the comparison should be done. It's pretty much a foregone conclusion that picture quality will not be noticeably different between copper HDMI and fiber at reasonable lengths within the copper HDMI cable specifications.

[JR-rpvr]

Speed is what I'm interested in with shorter cables.
I'm sure there isn't a noticeable difference but the fact remains that light/fiber is superior to copper.
I'd like to see a ping test through copper vs fiber hdmi.
I'm trying to figure out what device can do such a test.

great video...loved the video comparison!!!

[stevelawson]

As long as you adjust you tv to go high res the picture is fantastic

[teguhkembaren]

Why my 50M hdmi fiber not working again after 3weeks using it ??

[narutofanz]

Very informative video thank you very much

ME: watches this demo in 240p on a VGA display...

Years ago, I converted a coat closet to media closet and ran a CL3 rated (in wall rated) 50 foot copper HDMI in the wall, up in the attic, and down the wall from TV to closet, 1080p worked just fine, but once I switch to 4k on my oled tv and at the time new xbox one x, picture cut out immediately, that is the advantage to fiber optic!!

[laahah]

would using the fiber cable cut back latency ?compared to the other one

[gigabit]

There is NO Difference until you run longer runs. 15ft or more, go HDMI Fiber.
