HDMI runs the world, at least in my house. The only DisplayPort cable that I own is plugged into my PC, and that's largely because I don't have any other choice. For everything else in my house, it's HDMI or nothing. That's not a bad thing, however, as HDMI does everything I want it to. It even has some advantages over DisplayPort — HDMI-CEC being a big one.
The way HDMI-CEC works is that all your devices are interconnected and controlled by a single remote. If you have multiple devices plugged in, like a streaming box, game console, receiver, etc., then you have a lot of remotes lying around. Instead of having to use all of them to do specific things, HDMI-CEC, as long as it's turned on for each of your devices, lets you use one remote for it all. It's great when it works, but the reality is that it doesn't always work the way that it should. Even worse, this technology has been around for a long time now, and it doesn't seem like things are going to get better.
After putting up with these issues for a while, an opportunity fell into my lap. I was given the chance to review the SofaBaton X2 universal remote, and it was excellent timing since I was actually looking into a universal remote. With the Logitech Harmony line being gone, there weren't many high-end options. Fortunately, the SofaBaton solved my problems, and while it's not a cheap fix, it's the best one I can think of if you're looking for something that can truly do it all.
