Hi All

In a perfect world, one of the inputs on my UHD722 would support 120Hz passthrough. The PS5 Pro and Xbox Series X can both output 120Hz, and my TV can display it, but the UHD722 is the bottleneck. For a long time, I assumed there was no workaround, but it appears there may be one in the form of the HDfury 8K VROOM.

The VROOM has four HDMI inputs and two HDMI outputs and can be configured so that one output carries audio only and the other carries video only. That would allow me to route the VROOM’s audio output into an input on the UHD722 (so the UHD722 can continue feeding my Meridian G68J exactly as it does for my other sources), while routing the VROOM’s video output directly to the TV via a simple 2-in/1-out HDMI switch. The UHD722’s HDMI output would connect to the second input on that same switch. Only the games consoles would have their audio and video split, so the 120Hz video doesn’t pass through the UHD722.

All of this seems straightforward, although I appreciate the VROOM configuration will be fiddly. I’ll make sure the retailer can provide technical support for configuration. Before I go down this route, is there anything I’m overlooking that could cause unexpected issues in practice?

My main concern is how nicely the UHD722 will play with the VROOM, and whether the UHD722 will behave if one of its inputs is receiving an audio-only HDMI signal. Has anyone tested a similar setup, and if so, did it work?

I decided to go for the VROOM and have been really impressed with it. It does exactly what it’s supposed to by splitting the audio and video over HDMI without any issues.

For my setup, the four inputs go into the VROOM and then:

Audio: VROOM → UHD722 → G68

Video: VROOM → FeinTech SW212 HDMI 2.1 switch → LG OLED TV

All the other inputs on the UHD722 still work as normal. Audio continues to the G68, and the video output goes into the second input on the FeinTech switch, then to the TV.

Setup-wise, I thought the VROOM might be tricky, but in reality only two settings needed changing and it was easy enough to do from a computer. The interface is actually quite clear, and the unit shows its IP address on the front which helps.

That said, I’d never have figured out what to change without help. ChatGPT made it simple. I sent a screenshot and it immediately spotted the issue. The VROOM was limiting things to 4K 60Hz, and I wanted 4K 120Hz (which was the whole point of buying it!). Once that was fixed, everything worked perfectly.

Also, thanks for all your advice. It definitely helped me go ahead with it.

Have an Xbox Series X, HD621 and I bought Greg Wright's VRROOM!!!

I have VRROOM connected to EARC HDMI port of OLED and audio/blank video HDMI output of VRROOM connected to HD621.

I had Xbox Series X outputting uncompressed 5.1. 120hz HDR connected to OLED. The VRROOM pulls the sound from TV and sends it to HD621 as do other devices connected to OLED and VRROOM.

This works very well.

The UHD722 should process the output from VRROOM the same as HD621.
