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.
