OK, I was recently having issues with HDR and HDR gaming through Xbox One S. I did a little digging and found that the info page for the receiver had the wrong picture of the HDMI inputs on the back. This led me to think that the promised HDR with Firmware Update was a mistake.
After a half hour chat where I was first assured that the update had happened and that it should support HDR, I received confirmation that the 5790 is the same as the RX-V579 and was NOT supposed to have HDR.
Long story short, after nightmarish customer service exchanges where I was routinely ignored, both by email and phone, (as well as being provided a shipping label with my OLD address after asking for my mailing address in emails) I now have a brand new RX-V683 in place of the refurbished TSR-5790BL.
At first, they wanted to offer me a refurbished RX-V483 as this was the same price point or "level" of a receiver. I pushed back as the TSR-5790 had legacy connections like component and more HDMI inputs. Basically, I told them I would not accept losing ANYTHING for their error.
A lawsuit for false advertisement and failure to deliver would be much worse for them than making it right.
I have owned 3 previous Yamaha Receivers and I also own a Digital Grand Piano and a guitar amplifier. They treated me like crap, and now I would like to help everyone hold them accountable.
I am attaching a screenshot of the now changed website as well as a link to Amazon that still shows the erroneous info that was provided to them by Yamaha. https://www.amazon.com/Yamaha-TSR...a+tsr+5790
ATTN! UPDATE on how to do this. Also, it shows as expired on mobile, but mods have been alerted to hopefully fix that.
Basically, this is a standard case of false advertisement and failure to deliver on promised features.
1. Contact Yamaha AV support https://usa.yamaha.com/support/contacts/audio_visual/ [https]
2. Explain that you bought the receiver BECAUSE it was advertised as supporting HDR after a firmware update.
3. Show the screenshot to prove that up until just recently the Yamaha site showed this. You can also use Amazon and any other links you may find to show that they were and still are selling the models with that false information.
4. Make sure you have a receipt and tell whoever you speak to that you wish to exchange your receiver for one that DOES support HDR as advertised on the 5790.
You will probably have to go through several phone calls and emails, but you should eventually get a brand new RX-V683, which is a much newer and better receiver.
