Splitter and signal booster. That works great. I had another splitter and two signal boosters and still had range loss. I replaced everything with this splitter and all issues were resolved. I have two TVs on my patio with two 4K Fire TV Sticks. Fire TV for TV B is based on this splitter. The first split is connected to TV B HDMI 1, the second split is connected to TV A HDMI 3. The other Fire TV connects to HDMI 2 on TV A. The JBL 3.1 Soundbar connects to TV A via HDMI 1 ARC. If I want to watch the same thing on both TVs, I just switch TV A to HDMI 3 and I have sound and a perfectly synchronized picture. And to the programming I want to sound on. I installed a Fire TV connected to a splitter for a program I don't want to mute and left TV B with an HDMI 1. Sounds complicated, but it's a great setup.
