1. When input 4k 60hz, will it down to 1080p when the TV is 1080p?
XOLORspace answer: Yes.
2. When input1 4k 60hz hdr and output to two ports at the same time. One TV is 4K, and the other TV is 1080p. Will it down to 1080p? And will it display 4k 60hz hdr at the HDCP 2.2 TV, when the 1080p TV is turned off.
XOLORspace answer: Yes. It will down to 1080p to both ports. 43421 will not give change change to the 4k TV when the 1080p TV is simply turned off. It will go black on the HDPC 2.2 TV and come back again with 4K 60HZ HDR when the 1080p TV is unplugged. Here if the other port is connected to sound bar, also equals the same situation.
3. I want to display to TV and sound bar, can this product work?
XOLORspace answer: We suggest XOLORspace 23421 instead.
4. I have a Yamaha YAS 207 / 107 but when I switch one 4k 60hz input to one HDCP 2.2 TV, and the other port to YAS 207 / 107, XOLORspace 43421 can only display 1080p on my TV.
XOLORspace answer: We suggest XOLORspace 23421 when one output is sound bar. 23421 OUT B supports audio only and OUT A can pass through HDCP 2.2 video not identical to the OUTB.
