Customer Ratings & Reviews

First of all: lots of positives with this unit. Good sound quality, a pretty full suite of features for a reasonably priced unit (especially if purchased on sale or open box), etc. It really pains me to have to leave a bad review, but there were a few too many negatives to ignore: 1. This unit WOULD NOT under any circumstances pass 4k @ 120hz. I tried 3-4 different monitors/TVs, 3-4 different HDMI cables, and spent hours poring over the instruction manual and google searches. I've probably tried over 50 unique configurations of the above for testing. I even spent over an hour on the phone with an Onkyo support who admitted that I had done everything right, and could eventually offer more than trying some debug mode you can enter that ultimately did not solve the problem. We ended the conversation with him repeating "well it's not guaranteed to work with all equipment configurations, so Onkyo isn't going to process an exchange or any similar remedy because it's not our problem." That's great, Onkyo support guy, but the problem isn't that 4k @ 120hz doesn't work under A configuration. The problem is 4k @ 120hz doesn't work for me under ANY configuration. I have 8k high speed HDMI cords. I have a brand new PC and monitor. This may not seem like a big deal, but I SPECIFICALLY researched and purchased this model due to its confident marketing of 4k @ 120hz pass through capability. And Onkyo told me, in essence, "sucks to suck." 2. It's super lame and inexplicable why only the front left&right speakers have proper connections on the back. The rest are the tiniest terminals of all time that you're going to have to strip some of the copper off your speaker wires to jam in there. 3. This is neither here nor there as it is very likely a Windows/driver issue, but I've had intermittent trouble getting Windows to recognize this unit as Dolby Atmos capable. YMMV. Want to love this unit, but given the, from my perspective, pretty blatant false advertising and refusal to help me get a key marketed feature, I'm forced to leave a below average review.

Onkyo has long been struggling with HDMI issues, after my TX-NR 809 , i had read that Onkyo had overcome many of those problems, so when the oppertunity came up to by tge TX-NR5100, i thought it may be a better product, boy was i wrong, still having HDMI priblems, and now CEC and eARC as well, I literraly have to power reboot it every morning else the audio from both TV, cable and apple tv, goes into never land and does not come back until the TX-NR5100 is power rebooted (hold the power button for 5 seconds), sorry to say, I would not recommend.

Bought it for future proof, 8k but mainly because it has Bluetooth transmitter so I can connect Bluetooth headphones. Tried to connect it but it doesn’t stay connected, always disconnect after 10-20 seconds. Other than that there are no major differences between this unit and the one I use right now TX-NR555. Also the price suppose to be $499 when onkyo announced it. Because of chip shortage they increased the price to $599. Honestly it’s not worth the price to upgrade so I returned it.

Surprised that I did not like this unit. I had an Onkyo for 20 years and loved it until it expired. Replaced it with this one but could not get it to work with my TV. and the Record player did not work with Line input even with the preamp I have. Not sure why. I returned this unit and purchased the Pioneer and it is exceptional.

Bluetooth disconnects. Not even a year old and it’s giving problems

I can’t get it to turn up to a high volume not easy to set up. Plus I got absolutely no help at all. Customer service sucks there as well as the pryamid location. There car stereo division sucks really bad

This item that I purchased ended up being a defective item and now I have to wait for a new one and wait for another appointment for installation

Open box item , lasted a week. Had to return , store had no problem with my return
