VRR passthrough debuts on the TUF Gaming Capture Box CU4K30

Variable refresh rate (VRR) tech is everywhere these days. If you bought a gaming monitor in the last couple years—and not necessarily even an expensive one—there’s a good chance it features VRR. And since it’s one of the best innovations in modern gaming, we’ve outfitted our entire ROG and TUF families from top to bottom with G-Sync and FreeSync to ensure you can play your games at high refresh rates without tearing or stuttering. Now, we’re excited to offer VRR passthrough for the TUF Gaming Capture Box CU4K30. Existing owners can simply download and apply a firmware update to start enjoying fluid, tear-free gaming as they play and stream with HDMI 2.1 VRR-compatible hardware.

To find out if your display is compatible with VRR passthrough on the TUF Gaming Capture Box CU4K30, check with the manufacturer to confirm that it supports HDMI 2.1 VRR.

An easy choice for streaming

The TUF Gaming Capture Box CU4K30 makes it easy to share your gameplay with the world. Plug it into a compatible PC using a USB 3.2 Gen 1 port, and you’re ready to stream and record its output with your favorite software. The TUF Gaming Capture Box CU4K30 is certified for use with Open Broadcaster Software (OBS) Studio, and you can also use it as a source within Xsplit Gamecaster, Streamlabs OBS, and most any other streaming application that can accept a video source.

What devices can you connect to the CU4K30? Just about anything you can connect to an HDMI port: gaming consoles, PCs, even a mirrorless camera or DSLR. A dedicated 3.5 mm combo input lets you game using your headset and record console party charts to share your squad’s real-time reactions and in-game banter in addition to your gameplay.

VRR passthrough delivers pristine visuals

For many gamers, VRR is a must-have technology. If your display’s refresh rate is out of sync with your GPU, you’ll experience screen tearing—or have to rely on outdated tech like Vsync that introduces input lag. For gamers, that’s a lose-lose situation.

VRR neatly splits the horns of that dilemma by synchronizing your GPU and display. Your VRR-compatible display refreshes whenever a new frame is presented within its supported refresh rate range—and as a result, tearing and stuttering disappear. Frame rates naturally vary over time depending on the complexity of the scene being rendered, but as long as they stay inside the supported refresh range, you’ll enjoy smooth, fluid gaming experiences. Now that the TUF Gaming Capture Box CU4K30 supports VRR passthrough, you’ll have access to this tech as you stream your favorite games.

1080p48Hz - 120Hz

For VRR passthrough to work on the CU4K30, you need compatible tech at either end of the pipeline: both your gaming device and your display need to support the feature. If you’re gaming on a PC, your NVIDIA or AMD graphics card is almost certainly ready to go. The tech has also made its way to current-gen consoles, including the PlayStation 5, Xbox Series X, and Xbox Series S. Owners of an Xbox One X or Xbox One S can get in on the action, too.
