Given the very high-resolution screen, and the huge range of dashboard options (Apex have its own, I’ve opted for my favourite TWF dash for this review) there are so, so many options available for Vocore-powered DDUs. In terms of appeal, I would aim this particular product at the intermediate to advanced user who wants easily read race or qualifying data, without spending too much time looking at a wheel display.

In this review, we’re going to delve into the GT3R DDU’s technical specifications, the installation process, and share our final thoughts on the GT3R DDU Sim Racing Display.

Technical Specifications

The GT3R DDU Sim Racing Display is equipped with an impressive set of technical specifications that set it apart nicely from the competition and most definitely the vast majority of sim racing wheels that have built-in displays.

With its 5-inch high-resolution display, featuring a resolution of 480 x 800 pixels, small text and crucial in-game data are rendered with great clarity and precision. I found during use that, despite lots of screen pages being available – everything I need is clearly and easily visible on one page.

The tempered scratch-resistant glass overlay ensures long-lasting durability, while the 34 RGB programmable LEDs (that’s a lot of LEDs!) are controlled via SimHub (always have the latest version here). LED setup does take a while, despite profiles being available there are so many effects and rules available that you could spend days working on the perfect LED configuration. I like it simple: RPM, shift warning, spotter and flags.

The display’s custom PCB and single USB connection provide simple connectivity to your PC, further enhancing convenience and ease of use. Encased in a full 6061 black anodized aluminium enclosure and featuring a genuine 3mm carbon fibre mounting bracket, the GT3R DDU exudes a sleek and professional Motorsport aesthetic.

Installation

Setting up the GT3R DDU Sim Racing Display is a breeze, thanks to the thoughtful design, product page options and comprehensive instruction manual provided by Apex Sim Racing.

The package includes two carbon fiber brackets, mounting bolts, and a USB cable for easy installation. The brackets are designed to occupy the top mounts of your Direct Drive wheelbase (if like me you own a Simucube 2 pro – there are other mounting options available). The carbon fiber brackets not only provide sturdy support but also add to the display’s sleek visual appeal. Thankfully, they’re drilled in a way that makes the height of the display adjustable – so fitting it in with your existing setup should be a breeze.

SimHub

To get started, users need to install the Vocore Screen driver and configure SimHub. Most of us already have this done but to be sure, there’s never anything wrong with downloading the latest version of SimHub and simply following the install procedure. The latest version of SimHub offers to install a few drivers including the Vicore driver you’ll need for this display so, in my opinion, starting from scratch is not a bad idea.

Install SimHub, open it and start by heading to Devices > Add Device:

When you click “add a device”, look for the “Generic Vocore Screen” device:

Select the generic Vocore screen option and the full hardware settings available will appear for the DDU:

After the hardware installation is complete, it’s wise to make use of the LED profile created by Apex Sim Racing. You can download the file and the user manual here. Save this LED profile somewhere and follow these instructions:

Head to “Arduino” and select “RGB LEDS” from the top tabs. Click “Profiles Manager” (highlighted below)

Click “Profiles Manager” and upload the LED profile from the website:

Use the “import” button (a page with an arrow pointing to it – sorry should have drawn you a little box)

And that’s the hardware / software bit done, except of course for the universe of LED customisation options:

SimHub allows for *a lot* of customisation (including the option to build your own dashboard), including selecting a dashboard layout, and adjusting the RGB LEDs to perform functions from RPM lights (obviously) to spotter and flag effects during the race. The installation process, while involving a few steps, is straightforward and accessible even for those new to SimHub, all you really need is to sure you’re running the latest version of Simhub, and, if not, perform the upgrade process being sure to include the Vocore screen display driver. From there you can download and import the LED profiles which have already been configured for you.

Conclusion

The GT3R DDU Sim Racing Display from Apex Sim Racing delivers an exceptional sim racing experience for advanced users seeking an alternative to the usual built-in screens we’re seeing so much of lately. The unit’s vibrant 5-inch display, high-res graphics, and colourful display ensure clear visibility and readability of vital racing information. The 34 RGB programmable LEDs add a layer of immersion by providing real-time feedback on important data points such as RPMs, delta, and race flags.
