Cable Matters 2-Pack 8K HDMI Coupler (113105)
A well specified passive HDMI coupler for short joined runs, not a fix for long ones.
We bought HDMI Female to Female Coupler Adapter, F/F Connector, 3D HDTV 1080P Gold Plated. It's no longer documented anywhere, so this page reviews the closest well-covered match. It is the same kind of passive female to female HDMI coupler from a known cable brand that publishes full specs, at a similar low price.
The short version
- Anyone joining two HDMI cables to reach a TV, monitor or projector a few feet farther away
- Console and PC setups that want a coupler rated for 4K high refresh and HDR
- The total joined run is long, roughly 25 feet or more; get an active coupler or booster
- You can simply buy one cable of the right length, which removes a connection point
What owners like
- Rated well above what a 1080p setup needs, so it does not become the weak link in most home setups
- Simple way to add a few feet without buying a new long cable
Common complaints
- A passive coupler cannot boost the signal, so long joined runs can drop out
- Every extra joint is another point where the picture can fail, and some setups hit HDCP handshake errors

What it does
A passive female to female HDMI 2.1 adapter that joins two HDMI cables into one longer run, sold in a 2 pack; reviewed here in place of the unbranded 1080p coupler it resembles.
- Joins two HDMI cables so two short cables can stand in for one long one
- Rated for HDMI 2.1 bandwidth, so it also handles 1080p and 4K sources
- Passes HDR, VRR and ALLM for consoles and gaming PCs
- Passes surround formats including Dolby Atmos and Dolby TrueHD
- Needs no power
A sensible pick for anyone who needs to join two HDMI cables for a short extra reach, from a cable brand that publishes full specs and rates the part for 8K and high refresh 4K. The trade-off is that it is passive, so it adds nothing to signal strength, and long joined runs still need an active booster.

Questions
Does an HDMI coupler reduce picture quality?
On short runs a passive coupler generally does not. BGR says problems tend to start around 25 feet, and SlashGear advises keeping the joined length within the usual HDMI maximum and using as few joints as possible.
Will an 8K coupler work with a 1080p TV?
Yes. HDMI 2.1 is backward compatible, so it works with 1080p and 4K devices.
Is this coupler powered?
No. Cable Matters lists it as passive, and suggests an active booster for long runs.
Does it support 4K at 120Hz for a PS5 or Xbox Series X?
Cable Matters rates it for 4K at up to 240Hz with VRR and ALLM, provided the cables on both sides are certified high speed.
