Apple TV 4K with the HDfury VRROOM

The two settings that matter most

1. Audio — turn Change Format off. From the official FAQ: “Make sure your Apple TV 4K Audio setting Change Format is turned off. If you had it turned on to get at least Dolby Digital 5.1 out of your TV before you got VRROOM. Turn Change Format off, ATV4K will then detect the VRROOM as Atmos compatible.”
2. Video — no special resolution setting needed. From the official FAQ: “The HDfury VRROOM will be detected as a 2160p120 4:4:4 10b or 8K60 4:2:0 10b capable device by the source and it will always accept and process the highest quality stream from your source devices.”

Dolby Vision (LLDV) to an HDR10 display

From the official FAQ — How should I set ATV4K if I’m trying to display DV content from LLDV source to a HDR10 display?

“Note that when you start up the ATV4K the first time after configuring the LLDV EDID in the HDfury device, the ATV4K should bring up a prompt asking if you want to test for Dolby Vision compatibility. You need to pass this test before any LLDV would be output. Passing the DV test will set video to 4K Dolby VIsion, so you would need to reset it to 4K SDR if that is your preferred option.”

“Also, if you ever change the configured EDID, the ATV4K will notice and ask you to test for Dolby VIsion compatibility again. Once you pass the test with a particular EDID, the ATV4K will remember the next time you configure that EDID and not ask to test Dolby Vision again.”

“There is an additional option: Match Frame Rate that will output the same frame rate as the source is encoded rather than always upscaling to 4K60.”

How to enable the conversion on the VRROOM side is covered in the LLDV>HDR10 chapter of the manual FAQ.

Audio and Netflix

Netflix on ATV4K only show 5.1 titles?

“One tip to save other Apple TV users some confusion, it may not say Atmos in the menu of the app (ex 5.1 in Netflix) you’re using at first, but as long as you see Atmos under audio settings, just begin playing content you know supports Atmos and the app will adjust. Prime Video and Netflix seems similar in this regard.”

Atmos everywhere except Netflix?

“Simply go into your Netflix account setting on a Laptop and check your audio payback setting and make sure it is set to high and not any lower and restart your source.”

Lip-sync

From the audio FAQ: “For folks with an Apple TV, the Wireless Audio Sync feature will automatically and very accurately take care of remaining (audio before video) sync.”

Remote and CEC quirks

Remote no longer controls the sound system volume?

“A: Re-sync the ATV4K remote with your ARC or eARC sound system.” The manual also explains why: “ATV4K source remote is different because it just waits if there is ‘audio system’ device on the network that it can control. […] That will only work if the source sees an audio system in the CEC network.”

TV does not turn off with the ATV4K?

“Some users also reported success by toggling above ATV4K option OFF>ON and some had success by toggling TV CEC OFF>ON.” And the LG OLED trick from the same answer: “When turning off your ATV, keep holding the remote towards the TV and it will turn off the TV. Works every time.”

The full answers — including the sleep-timer caveat — are in the ATV4K chapter of the manual FAQ, and volume problems have their own step-by-step troubleshooting page.
