Sell me on Denon

[Warm Gun]

I have a working Onkyo 575. But it can't pass through 4K 120 Hz 10-bit. Signal gets reduced to 8-bit or from RGB to Yuv -- can't remember which. The graphics card only has one HDMI output, so I have to use a DisplayPort to send picture to the TV and then send a second phantom display to the AV receiver for sound. My windows and icons sometimes disappear there. I would like to remove that phantom display and simply send the video signal through the receiver to the TV. But that's not worth 400 dollars.

Discovered another problem today. I can kind of get VRR to work in the AMD settings, but only if I remove the DisplayPort adapter. Another incentive to send the signal through the receiver and drop the phantom display.

The receiver I'm thinking about is the Denon 760H. Are there any other excuses you can think of? My Onkyo has no problem passing Dolby Vision through from my player and I don't use any 120 Hz devices except for the PC. Is the user experience any better on Denon?

Actually, since the TV and Denon have eARC, I could send the signal to the TV and then onward to the receiver. Wonder if the audio lag would be noticeable or if passthrough is crummy. Heard passing video through the receiver to the TV can be too slow for PC gaming.

If your TV/monitor is 120hz, it's best to connect the game console direct to the TV, not through the receiver for that reason.

Can't do that because my receiver doesn't have eARC. One guy told me eARC is a mess. Thinking about it again, not confident VRR and dropping the phantom display is worth it at 400 dollars and tax. Especially if VRR only works at 48-120 Hz because of AMD's incompetence, presumably tearing if the game drops below 48. I had to do this to be able to turn AMD FreeSync on:

Wahey! I decided to try again with EDID spoofing, and had more success this time.

Download Custom Resolution Utility by ToastyX and run it.


Select your TV from the list.
Click the CTA-861 extension block.
Click the HDMI 2.1 support data block.
Click edit.
Take note of the listed VRR range.
Click cancel.
Add a new "Freesync range" data block.
Set the correct VRR range from the previous step.
Click ok.
Unplug and plug in the HDMI cable to the TV.

For me, this did enable VRR. Unfortunately on the A90J it's 48Hz, which is a pretty high threshold, so in the most demanding test I ran (RE8 with raytracing) there was still some tearing in very specific spots (like, you are looking at this room from such and such an angle and I guess that causes the framerate to dip just below the threshold). It might be possible to force a lower threshold and not totally break, I haven't tried that yet. I know it doesn't go down to 20-25 for my TV, because that was what I had tried originally.

And to be clear, I really really shouldn't need to do this whole dance to make it work -_-

Would have been nice to also use it in movies (so below 48 frames), but changing framerates (23, 24, 25, 29) through the Windows Display settings is much less buggy than doing it through the Nvidia Control Panel like I used to. Will just keep using V-sync for now. I didn't use VRR long enough yesterday to find if it's the shit, before connecting my DisplayPort adapter again.
