In with the New

Redmere, Redmere, Redmere! It’s the revolutionary technology that has succeeded in finally improving HDMI by adding another dash of elegance and efficiency. But what’s all the hype about and is it really worth it? What kind of sorcery is this? In the simplest terms, an HDMI with Redmere cable like the HDMI-RDMR contains a tiny chip in the head that acts as a booster and an equalizer. This method of signal enhancing doesn’t require an external power source. The chip is small enough to work using the 5v natively carried through HDMI. This heightened strength means the cable can carry signal farther using less copper, making the cables much thinner than ordinary HDMI.

The HDMI-RDMR drastically outperforms in flexibility and portability. They can easily bend up to 180 degrees at less than a ¾ inch radius, making them perfect for use behind a flat TV mount. Even the heads themselves are significantly shorter, reducing the need for TV mount spacers and right angle adapters. You don’t have to sacrifice cable length for this feature, either. In fact, HDMI with Redmere cables can carry signal longer distances than those without the chip. They have been tested in lengths up to 130 feet without any loss in video or audio quality.

Plug Away

You don’t have to wait for a special occasion to upgrade your system with this cable. They can be used in place of a regular HDMI cable anywhere, anytime. All you have to remember is that HDMI Cables with Redmere are directional. That means they will only send the signal in one particular direction, so you must be sure you connect them correctly for them to work. The ends are clearly marked. Just attach the cable with the Redmere logo to the display. Plugging them in the wrong direction will not cause any harm, you just won’t get a signal.


Can RedMere HDMI cables be coupled with regular HDMI cables?

Yes, the two will work together with the use of a coupler or adapter, as long as you heed the directional nature of the RedMere cable and make sure the correct end is plugged into your device.

Your Rating


Is this cable directional?

Yes, this cable is directional. Both the source and display ends are labeled on the cable.

Is this cable 4K rated?

That depends on whether your TV requires HDMI 2.0 for 4k signals. If it does, you will need to purchase a 2.0 HDMI cable for your 4k resolution. If it does not, you can use these cables to transmit 4k.

Is this HDMI 2.0?

These cables are not HDMI 2.0, so they will not transmit HDMI 2.0 signal. Not all televisions require HDMI 2.0 to work properly, though. Refer to your product manual to determine if your television is HDMI 2.0 or not. If it is, we also offer Premium HDMI 2.0 cables!

Will this work with my gaming console?

This cable will work with most modern gaming systems, but make sure your console has an HDMI port.

Why is this directional?

The Redmere booster chip uses the 5V power from your display to work. That means the end designed for the display must be plugged into the display.

Can I use this with a gaming console or streaming media player?

You can use this cable with most gaming consoles and streaming media player, but some devices do not have the initial signal strength to make it 75' and 100'. We do not suggest using this cable with "stick" style streaking media players such as the FireStick or the Roku Streaming Stick.

Can I use this with a phone, computer, or tablet?

You can use this cable with computers and laptops, but most phones and tablets do not have the initial signal strength to make it 75' and 100'. Additionally, you may need an adapter to go from your device to a standard size HDMI cable.

Can I use this with a camera?

Even with a boosted cable, 75' and 100' is typically too far for camera signals to run. Please consider running the camera to a computer first or using another HDMI extender method. Additionally, most cameras require an adapter or converter to go to standard HDMI.

What length cable do I need?

That just depends on how far apart your source and display are. The best way to determine that is by measuring. Use the shortest length possible, but round up if your measurement is in between two sizes.

Can I use this with a splitter or switch?

Yes, you can use this cable with a splitter or a switch. This cable can only be used on the splitter/switch to television/display side of your run, however. They cannot be used from the source to the splitter.

Can I use this with my projector?

That depends. This cable requires 5V power from the display to work. Please contact your equipment manufacturer to determine if your projector can be used with active HDMI cables.

What if I need to go longer than 100'?

To go longer than 100', you can use HDMI over Cat6 extenders, HDBaseT extenders, or HDMI fiber cables.
