One TV. Every Console. No Port Drama.
If your TV has only two full-bandwidth HDMI 2.1 ports, the problem is not just the number of sockets. It is deciding which devices deserve the 4K120 path, where eARC audio should live, and how to avoid handshake failures.
Keep the soundbar on the TV eARC port. Put PS5, Xbox Series X, gaming PC, and other high-performance sources on a full-bandwidth HDMI 2.1 switch. Use certified Ultra High Speed HDMI cables for the 4K120 path.
Why Two HDMI 2.1 Ports Get Crowded Fast
Many TVs reserve one premium input for eARC/ARC. Once a Dolby Atmos soundbar uses that port, PS5, Xbox Series X, gaming PC, Switch 2, Apple TV, and capture cards all compete for the remaining full-bandwidth input.
The clean solution is to keep audio return simple and put the devices that actually need 4K120, VRR, HDR, or ALLM on a reliable HDMI 2.1 switch.
Which Devices Need the Best Path?
Put it on the HDMI 2.1 switch path for 4K120, VRR, HDR, and ALLM.
Best on a full-bandwidth input or the same reliable HDMI 2.1 switch.
Usually needs the strongest signal path, especially with OLED or Mini LED gaming TVs.
Often fine at 4K60, but can join the switch for cleaner input management.
Usually fine on a standard 4K HDMI input unless you want one-button switching.
Keep it on the TV eARC port for simpler Dolby Atmos audio return.
Recommended Setup
- Connect the soundbar to the TV eARC/ARC port.
- Connect the MROCIOA S5 Pro or another HDMI 2.1 switch to the other full-bandwidth HDMI 2.1 port.
- Connect PS5, Xbox Series X, gaming PC, and other high-performance sources to the HDMI switch.
- Connect lower-bandwidth devices to standard HDMI ports if your TV has them.
- Use certified Ultra High Speed HDMI cables for every 4K120 path.

FAQ
Do I need an HDMI 2.1 switch for Nintendo Switch 2?
Not always. If your setup is mainly 4K60, Switch 2 may not need the most valuable HDMI 2.1 port. Adding it to the switch can still keep the setup cleaner.
Should my soundbar go before or after the HDMI switch?
For most users, the soundbar should stay on the TV eARC port. Put gaming sources on the HDMI switch.
Can one bad HDMI cable break the setup?
Yes. A 4K120 signal chain is only as strong as the weakest cable or device in the path.
