Xbox series X issue. HDMI ARC port is no longer working.

no it wont. it says "this didnt work" and shows the list of stuff with Dolby having the red x.

my 4k tv has an arc hdmi and other hdmi port. that doesnt matter does it?

as my ps4 pro is in the arc port.

Why is my Xbox series x screen so small when I turn it on it just started doing this a few days ago. Please help it’s not the tv because everything else I use it for is normal. Update I just unplugged my hdmi and plugged back in and that fixed it. It’s in the arc hdmi input but why did the issue happen to begin with?

hello 👋 fellow gamer HDMI ARC has a higher 👆 bandwidth for higher bit rate and data transfers as well as some other features that default HDMI port's don't have, I've had similar things happen before especially when using DVI to HDMI adapters on HDMI ARC

I had the same / similar issue with my old 4K 60hz none HDR / HDMI 2.0 monitor when watching movies and some times in games with the Series X,

As soon as i upgraded my monitor to a 4K 144hz monitor that has HDR / HDMI 2.1 ports, i no longer had this problem,

I'm not sure what the problem is, but my guess is that the HDMI 2.1 port on Series X doesn't play well with HDMI 2.0 port of monitors, or it's the Series X trying to force HDR on, even if the monitor does not have / support HDR and the HDR in Series X menu's is turned off.

I also have the same setup. Xbox Series X conneted to Samsung TV via HDMI. Samsung TV connected to a Klipsch sound bar via HDMI ARC. Experiencing the same issue described by many others.

Thanks for your reply. I understand the PS4 does not support 4k, but my Fire TV cube does. I plug my Fire TV into the HDMI in on the soundbar, and it plays in 4k and the soundbar recognizes Atmos. My tv is a Sony Bravia about 3 years old, so it does not have HDMI 2.1. I searched my owners manual, the settings on the tv, and the internet and could not find anywhere what version of HDMI my tv supports. I assume it is 2.0.

I am using the HDMI cable that came with the soundbar, no way to tell which version it is.

What I don't understand is why would my Fire TV pass through the soundbar correctly and provide Atmos sound? And also, why did my Series X work for a short time, and now won't? I was able to watch several UHD Blu-ray discs on the series x and was able to get Atmos. Then a few days ago, the XBox will not pass through the soundbar. I had to plug it back into the tv directly where I cannot get Atmos sound.

Another confusing thing is I plugged the soundbar into a different HDMI input on my tv, not the HDMI arc port (I don't have eARC, just ARC) and the XBox was able to pass through the soundbar correctly. However, this messed up my cable box sound since the soundbar was no longer connected via ARC. I used a digital optical cable for the cable box but had sound sync issues. Could it be some conflict with the HDMI arc input on my tv and the XBox? If that was the case, why did it work for a short time?
