I used to have/need a switch, but now not any more since I moved, more rooms, so able to spread out stuff.
Living Room-just the Roku and 4K Blu Ray Player ( that I never seem to use), that is hooked up to the Pre-Pro which has 7 inputs , but only need 2, then hooked to the Sony TV.
Have a Tablo in there, but that is hooked to the router so all the rooms have a OTA DVR.
Game Room- XBox X, Switch and PS5 hooked to the TV direct, eArc to the Receiver.
This room is only used for Games, so no need for anything else.
Outdoor Patio Theater-Roku and Blu-Ray ( that I never seem to use) to the Pre-Pro then to Projector.
All the other Rooms have TCL Roku TVs, they will only get used when I have guests, so no need for any other equipment.
Today’s world, 3 HDMI inputs should be more then enough, unless multiple streaming devices or Game Systems, most TVs have 4, Pre-Pros/Receivers have 6.
The problem is eArc, takes away a input when hooked up to a soundbar/Receiver/Pre-Pro.
