My AVR would drop the lowest setting, so those cheap HDMI to A/V only support up to 1080p, so it would cause my my Media Center to drop to 1080p when my Ambilight was connected.
After this device, 4K 60, HDR10+...no problems at all. Tested 4-5 different movies...
Yes, use a decent cable. I noticed fairly good cables that are short will carry 4K 120hz no problems (I have a Xbox Series X) but, go past 10 feet, all bets are off. If you are using a 6 foot or less, unless it's really cheesy you'll be fine.
There is a setting in the menu where I could set dual output, or select another device. I do have a Denon AVR-X6200W, not sure if there is a difference here. I know the VSX-90 is a newer model, id bet there is a setting for this.
Check your on screen menu settings....
Thanks but I explicitly checked in the manual and they state the config I want to do is excluded. I suspect it is yet more copy protection someone required. Very disappointing but the splitter I got works great including CEC.
