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

I have a GMKTEK K6 that is plugged into my TCL QM851 TV. My CEC wasn't working. I unplugged everything and started to build it out... TV+Soundbar = CEC worked; TV+Soundbar+Shield = CEC worked. TV+Soundbar+Shield+Mini PC = CEC didn't work.It turns out the MiniPC was putting a load on the HDMI pin 13 -- interfering with CEC devices. This solution blocks pin 13... so I plugged the adapter into the HDMI cable going to the mini PC. Now the whole TV, soundbar, Shield and MiniPC work great.Important to note: The MiniPC is at 4K 120Hz...this adapter passes the 4k 120Hz perfectly... for higher refresh rate gaming.

Simple and just works. I upgraded my classic Roku Streaming Stick+ to a new Streaming Stick 4k as the new sticks have much better WiFi performance. Problem is, Roku added some unnecessary smarts to the new stick. With the old stick, I turned on my TV, and the Roku and my Bose soundbar all came on together. The new 4k stick broke that, and my soundbar wouldn't power on automatically anymore. I added this to block the CEC signals from the new Roku stick, and all is good again.

Perfect for my use case. My vizio sound bar would randomly increase volume because of my tv. If you are having odd problems even when you disable arc i would try this.

I'm not sure who the geniuses are who decided my devices need to turn each other on and off without my prompting, but the functionality cannot be disabled on either my Samsung TV or my 4K player. This device acts a supervising adult between the two, keeping them from exhibiting this very unwanted behavior.

I found a 4K Blu Ray player (LG UP875) at a thrift store for $8 and decided to take a chance on it. The player worked perfectly except for the fact that it was turning on whenever I turned on the TV or receiver. I figured it was a CEC issue. I searched the manual and online but the answer seemed to be that there was no way to fix this issue in the settings. This adapter was the fix. I figured I would lose the ability to use the volume and input commands, but those continue to function without the player getting turned on by the other equipment. I hate that I had to drop over double the cost of the player on this adapter, but I'm still way ahead of what it would cost to buy something new. Recommended.

Worker as intended. It blocks a CEC. Ended up returning it since it did not resolve my Samsung Soundbar dropping arc. I ended up settling and turned bitstream off and going back to pcm. With this product just be mindful of your HDMI port location as its basically the size of the bulky end of your typical HDMI cable. You might not have enough room to run your HDMI cord or need something with a right angle.

Was having issues with soundbar. Turns out CEC from the devices on my HDMI switch were causing the issue. Put this on the output of my HDMI switch. No issues since.
