The Royal Kludge RK84 is a popular mechanical keyboard known for its sleek design, wireless capabilities, and customizable features. In this review, we explore its wireless connectivity options and latency performance, providing insights for gamers, typists, and tech enthusiasts.

Design and Build Quality

The RK84 features a compact tenkeyless layout with a sturdy aluminum top plate and durable plastic sides. Its minimalist design is complemented by RGB backlighting, which can be customized through dedicated software or onboard controls. The overall build quality feels premium, making it suitable for both office and gaming setups.

Wireless Connectivity Options

The RK84 supports multiple wireless connectivity modes, including Bluetooth 5.1 and a 2.4 GHz wireless connection via a USB dongle. Users can pair the keyboard with up to three devices simultaneously and switch between them effortlessly using dedicated keys. The Bluetooth connection provides a stable link within a typical range of 10 meters, while the 2.4 GHz connection offers a more reliable and lower latency experience.

Bluetooth Connectivity

Bluetooth mode is convenient for connecting to laptops, tablets, and smartphones. The connection process is straightforward, and the keyboard maintains a stable link with minimal lag during regular typing and media control tasks. However, during high-speed gaming, Bluetooth may introduce slight latency, which can affect responsiveness.

2.4 GHz Wireless Connection

The 2.4 GHz mode, enabled via the included USB receiver, is designed for gamers and users demanding lower latency. This mode provides a more direct and faster connection, significantly reducing input lag. The connection remains stable even during intense gaming sessions, making it the preferred choice for competitive play.

Latency Performance

Latency is a critical factor for gamers and fast typists. The RK84's 2.4 GHz mode demonstrates impressive performance, with reported latency of approximately 1-2 milliseconds, comparable to wired keyboards. This low latency ensures quick response times, which is essential for competitive gaming and precise typing.

In Bluetooth mode, latency increases slightly, averaging around 10-20 milliseconds. While still acceptable for casual use and office work, this may not be ideal for fast-paced gaming where every millisecond counts.

Additional Features

  • Hot-swappable switches for easy customization
  • Programmable keys and macro support
