Does the TX-SR373 support HDR properly? When I try passing an Xbox One X signal through this receiver, it cannot convince the Xbox and TV that HDR is working. I've verified it's not the cables by plugging Xbox directly to TV, and verifying that HDR works. The only way I could get HDR to work through this receiver is by setting the HDMI input to 4:4:4 and setting the receiver to not process the HDMI signal (therefore there's no sound to speaker system). I'm hoping it's just a setting or faulty receiver, because it's clearly advertised as able to support HDR.

Tried another scenario: - Still passing HDMI through the receiver to TV, using the BD/DVD input on Onkyo receiver. - Turned off audio coming through HDMI, use optical to output audio from Xbox to Onkyo receiver. - VIa quick menu on Onkyo receiver, set HDMI sound mode to 'THRU' (meaning no audio amplification).
The above setting allows full 4k with HDR to get to TV, but there is no sound from speakers. Now here's the part that says something is odd with the receiver. For the BD/DVD input, the receiver can choose different inputs for it's audio, so I set it to process the audio from the optical signal. As soon as I do this, the HDR does not work anymore. It's like using the Onkyo receiver to decode audio signals is interfering with the 'video' portion of the HDMI signal.
Hello. We are currently looking in this matter. While the TX-SR373 does support HDR. There appears to be compatibility issues with the way HDR is processed/recognized. This problem did not occur with the "S" version of this console. At this time Onkyo recommends connecting the Xbox directly to the television, and using either ARC or Optical to get the audio back to the receiver.
As an update to this, we have trialed the Xbox One X in our lab and have had no problem passing through HDR using the TX-SR373. All "Green Checks" were displayed next to HDR.
Can you post the configuration the SR373 is using? I've tried 'factory default' reset on the receiver and still couldn't find a configuration to make this work. If it turns out my unit is defective in some way, what recourse do I have? It's 6 months old.
Please make sure you have the 4K settings under HDMI SET are set to 4:4:4. You can attempt to factory reset the receiver as well, (this will clear all settings on the receiver). To reset the receiver please follow these instructions:
Use this procedure to reset all the receiver’s settings to the factory default. Use the front panel controls to do this.
1 Switch the receiver into standby. 2 While holding down STEREO, press and hold ON/STANDBY. 3 When you see RESET? appear in the display, press SURROUND. "OK?" shows in the display. 4 Press "DSP" to confirm. "OK" appears in the display to indicate that the receiver has been reset to the factory default settings.
In addition, make sure you have high speed HDMI cables capable of 18.2gb/s bandwidth.
So I did factory reset. Set all HDMI inputs to 4:4:4 and still no luck. As a I stated earlier, if I put the receiver into 'HDMITHRU' mode, then the HDR signal is good. But that means no sound through speakers. So I ran out and was able to exchange for a new Onkyo sr373 receiver, but still cannot get HDR to work. So now I suspect it might be the cables..? But I verified all the cables I use by connecting the Xbox directly to the TV, and HDR works fine then.
What cables are you using in your lab? Do you have a recommendation for a brand?
Hello, running a cable from the source to the display is not a good judgement of cable quality. It is just the easiest. By adding a receiver in the middle, the voltage is affected and it is even more critical to get a better cable. We used Audioquest and Monster cables in our lab for the trial.
I went and got 2 monster Ultra HD platinum cables. It still doesn't work. This is a new unit (another sr373) and it's not cabling or settings. Just want to re-iterate, it passes the full HDMI signal through when it's NOT doing any sort of audio decoding. Thanks for the help though.
