BlueRigger HDMI CEC Less Adapter (4K UHD, ARC, Ethernet, Male to Female HDMI CEC Blocker) - Compatible with HDTV, TV Stick, Chromecast, Nintendo Switch, Xbox, PS5, PC, Soundbar

Solved eARC audio problem with Spectrum box! BlueRigger CEC Adapter installed at Spectrum cable box solved audio drop out issue that prevented eARC from working (at all) & (even) corrected Optical output drop-out through Samsung OLED TV to my Yamaha Home Theatre Receiver

Worked great with my anthem Avm70 4k it always defaulted to PS5 because I’m using eARC From an LGOLEDG5

I recently got a new sound bar that requires enabling CEC to get Dolby Atmos. This all worked great, except that my Mac mini started fighting over input priority and would turn the TV on every five minutes. There is no way to disable CEC without disabling Dolby Atmos. So, I bought this little adapter hoping it would help. It did! Installation was simple and I still had 4k DV-HDR 120Hz and Dolby Atmos. The input is still properly recognized and all the issues I had are now gone.

The Samsung TV "thinks" there is no video from the TiVo. This was recommended, but the TV ignored it, no matter what HDMI input was used. I had to get a HDMI 2 port switch, turn on TV, press input selector and video returns. Both tech support groups blamed each other. It took too long to troubleshoot and return window closed.

I use an HDMI splitter to share a KScape player in two rooms. In one of the rooms, I use a Sonos Arc Ultra with an LG TV. Unfortunately, to use eARC, CEC must be turned on in the TV. CEC was then causing the TV in the room room and an Apple TV in the other room to be linked inappropriately. I spent a lot of time and money looking for a solution. Someone suggested this device on a Reddit forum and I immediately bought it. It worked perfectly to break the unwanted CEC connection. It is such a cheap solution compared to the eARC HDMI switches I was trying!

Purchased to solve recurring issue with Roku HDMI/HDPC error. Seemed to work for several weeks, it still occurs occxasionally.

These worked well for what we used them for which was to remove CEC from one device connected to another as we had one device with a defect that would not operate properly without having the input signal stripped of CEC (firmware issue that the manufacturer would not fix)

A lifesaver for this MiSTer FPGA user! My TV ecosystem works again. No negative effect on audio or video quality. Easy to install, took like 5 seconds. Connects just like an HDMI cable

Good quality. Able to upscale the picture with 3D. Not suitable for all devices. A good choice for anyone who has a reputed device.

This adapter is a life saver. My TV Box now no longer interferes with AV receiver’s audio from the TV over HDMI ARC. Earlier, I accidentally discovered that the Sony Bravia’s audio worked with Yamaha 7.2 AV receiver only with the TV Box disconnected. The TV box’s HDMI CEC feature was supposedly causing the ARC “handshake” between TV, AV receiver and TV Box to malfunction. There was no audio from AV receiver. While searching on google, I came across a blog that pointed to this CEC-less HDMI adapter. Realizing the root cause of the problem, I was certain this adapter would do the job. I ordered this a week ago and it arrived today in Dubai. I tested connections this evening and all works perfectly now. I am so happy. This adapter can connect to the TV-end or the TV box-end of the HDMI cable. It doesn’t matter. Make sure you first determine what device is causing the problem and then use this adapter to block CEC signal on that particular HDMI device and cable.

My Samsung Q870A/XY soundbar has worked with my Samsung TU8000 TV for a long time without issue. Have always used the eARC function so I can control soundbar, TV and NVIDIA Shield Pro using the Shield (or Samsung TV) controller. For some reason that eARC / CEC functionality suddenly stopped working and my Samsung TV no longer recognised by Samsung soundbar. Perhaps it was a firmware update on one of the two devices, HDMI handshake issues or a device introduced a CEC conflict? After much painful power cycling, HDMI cable testing, HDMI cable swapping, general diagnostics and forum trawling I worked out what the issue was. If only the soundbar was connected by HDMI to the TV eARC HDMI port then soundbar and TV worked. As soon as any other device was connected to HDMI 1 or HDMI 3 (the non eARC spare inputs on my TV) the soundbar would drop off and wouldn’t be ‘seen’ by the TV. That’s when I learned about my new nemesis: PIN 13 in HDMI causing issues with unwanted CEC signals. Yes, as described on some websites you could get some pliers and a magnifying glass out to prise out the offending pin on one of your cables, or you could carefully tape over pin 13 with electrical tape. Realistically though, why would you risk messing up thousands of dollars worth of equipment in lieu of testing a $14 delivered solution with free returns? Anyway, I bought 2 of these for the 2 non-eARC HDMI inputs on my TV and everything worked immediately. I now have my Switch and PS4 rigged up with the soundbar fully working on all sources with Atmos. Why Samsung and other AV companies don’t suggest testing CEC-less adapters as part of the troubleshooting process is beyond me. I don’t normally bother leaving reviews, but this problem was ‘doing my head in’ so I’m leaving as much detail as possible to help anyone else in a similar boat. I’d say if most of the above sounds familiar to you (even with different branded equipment) then this device could well be the solution you’re looking for. Good luck!

I had been having problems with a new Free sat box which was switching other HDMI connected devices on and off at random, it was driving me nuts and I was going to scrap the new Free sat box to stop the problems, then I found this and straight away it cured all the HDMI issues I was Getting. Great little adapter to stop HDMI Issues.

I have a Sony xj90 tv. When the tv is turned on the arc device wouldn't work. The tv would never see the device. So to get it to work I had to always setup the arc device again and again. What I learnt was when the tv is powered on it polls for connected HDMI devices in order 1, 2,3 etc. Arc is HDMI 3. Which meant anything plugged into HDMI 1 and 2 would prevent the tv from recognising the real arc device. This little device blocks the tv from seeing those first 2 HDMI ports and now always sees HDMI 3 as the arc channel and my speakers no work perfectly.
