Do I Need New HDMI Cables for a 4K UHD TV?

    Hello everyone,

    I'll be replacing my Sony 52" LED TV with a new OLED 4K UHD TV within the next few months. I have good HDMI cables on it right now, but I want to know if the newer OLED 4K UHD televisions require a higher grade of HDMI cables (if there is such a thing). Current TV is wall mounted and our seating area is 9'-10' away.

    Any thoughts?

    Thanks,

    Michael

    Depends on how old the cables are and the quality / grade / rating on the ones you have are.
    You need to replace it if they were not high speed cables capable of a minimum of 18 Gbps or said 4k capable. The programs with HDR profile need these higher speed cables.

    Today those types of cables are not necessarily expensive. I bought 1 for $14.99 that is 6 ft long and it works fine.

    Thanks for the response. I bought my current HDMI cables from Best Buy about 5+ years ago. At the time, they were the best ones that Best Buy had. I don't know if they were rated Certified Premium High Speed. Since they are over 5 years old, I'm guessing that they are not of the Premium High Speed variety since 4K was not on the horizon yet. Would I have to replace all the HDMI cables (i.e., Hopper 3 to Receiver, DVD player to Receiver etc.?)

    current requirement is 18 Gbps,
    don't read into that misleading marketing words - stick with real physical parameters: speed and attenuation/max length

    Only the cable (s ) that will be sending the 4k content.
    If you send your signal from the Hopper to an AVR ( surround sound receiver ) the receiver must be capable of letting the 4k content thru. If your receiver is old like mine you will need to send the Hopper signal direct to the 4k TV and use an Optical / Digital coax from the Hopper to the AVR.

    ...and please don't spend a lot of money at Best Buy if you decide to replace your HDMI cables. Monoprice.com is a great place to get inexpensive reliable cables for anything. As stated, look at the specs. A $96 Monster cable doesn't pass digital data any better than a $6 Monoprice cable. Amazon always has some good prices too.

    Yup, don't get sucked into the Monster mess. Way overpriced, but I bet it's a nice HDMI cable.
