How to turn a Windows 10 tablet into a dashboard for Forza Horizon 4

There's a lot of information hitting your eyeballs when you're playing a racing game like Forza Horizon 4, Forza Motorsport 7, or Project Cars 2. The on-screen HUD is useful, but it can be hard to properly absorb when you're focusing on driving hard, especially if you're using a racing wheel.

That's where you can improvise and build an external dashboard display. And no, it isn't some kind of expensive or highly technical exercise. In fact, you can do it with any Windows tablet or laptop. A tablet is probably easier to use, though, in this situation!

All you need is your Windows 10 device and a free app from the Microsoft Store called RealDash.

RealDash also works on real cars with the right hardware to connect to, but in this case, we're only interested in the virtual ones. It's free to download and use, though there are premium in-app purchases for different dashboard designs. Or you can stick with the included ones.

Once you've installed it on your machine, you just need to connect it to Forza Horizon 4.

How to connect RealDash to Forza Horizon 4

  1. In RealDash, click on garage.
  2. Click on the door handle of the car you see.

You'll now see Forza Horizon 4 listed under connections when you select the car's dashboard. Whenever you have RealDash open, it will try and connect to the port you enabled in the game to receive its telemetry. One limitation I've found is that with more than one game in your connections list, it will try to connect to the others while you're playing with an annoying on-screen message. But it's not a big deal to re-enter games and match up the ports.

There are limitations, mostly game dependent. For example, Forza Horizon 4 will output data for tire temperatures, but not brake temperatures, and also in this game, it'll tell you what lap you're on but not how many total laps there are.

The good thing is that you can customize your dash, so if there are gauges that don't work in your chosen game, you can just remove them. Likewise, if you just don't want some of the data you're being shown.

The setup process is very similar for Forza Motorsport 7, and RealDash also supports several other games, including Assetto Corsa, Euro Truck Simulator 2, and F1 2019.

This works well on any Windows 10 device, but the real beauty is when you have a small tablet — something like an old Dell Venue 8 Pro (opens in new tab) — and a way of mounting it by your wheel. Or if you have multiple monitors, maybe running RealDash on one of those while you race on another. There's also a version of the app for Android (opens in new tab) too, if you're interested but don't have a Windows tablet to spare.
