Razer’s breakthrough 4000 Hz HyperPolling Wireless Dongle tech is now hitting an expanded roster of its killer BlackWidow keyboards, bringing zero lag and lightning-fast input, basically confirming that wireless speed can now go toe-to-toe—and even beat—your old wired setup.
If you play competitively, you know the absolute truth: every single millisecond counts. Your average, run-of-the-mill gaming keyboard reports its status to your PC 1,000 times a second (a 1,000Hz polling rate), which leaves you with a minimum delay of 1ms. That’s not terrible, but it’s not cutting-edge either.

Razer’s 4000 Hz HyperPolling Wireless tech is touted to completely smash that latency ceiling. By boosting the reporting rate to 4,000 times per second, the time between you hitting a key and the PC registering the action is slashed to a ridiculous 0.25ms. In clutch situations, this quadrupled polling rate gives you a tangible edge, making sure your actions are executed virtually instantaneously when you need them most.
This technical wizardry is unlocked by the Razer HyperPolling Wireless Dongle, which plugs into your rig and maintains that stable, hyper-speed connection.
Razer isn’t keeping this blazing-fast tech locked up in its most expensive flagship. The high-speed wireless capability, which made its debut with the heavy-hitting BlackWidow V4 Pro 75%, is now spreading across the popular BlackWidow line, ensuring every gamer can find the right form factor without sacrificing speed.
The following legends are confirmed to be compatible with the 4000 Hz HyperPolling Wireless Dongle:
- Razer BlackWidow V4 Tenkeyless HyperSpeed: This compact warrior cuts off the numpad, instantly freeing up precious desk space for those massive, clutch mouse flicks.
- Razer BlackWidow V4 Low-profile HyperSpeed: Featuring snappy low-profile switches, this board is all about quick, responsive actuation and a sleeker, more ergonomic feel.
- Razer BlackWidow V4 Low-profile Tenkeyless HyperSpeed: This unit combines the minimalist, desk-friendly footprint with the lightning-quick speed and comfort of low-profile switches.
By injecting 4,000Hz wireless performance into these varied layouts—from the compact tenkeyless to the low-profile options—Razer is ensuring that whether your setup is big or small, your performance won’t be held back by lag.
Pricing & Availability
The Razer HyperPolling Wireless Dongle is sold separately and is essential to activate the 4000 Hz polling rate on the newly compatible BlackWidow models. The dongle and the compatible keyboards are expected to be available for purchase through Razer’s official website and authorised Malaysian retailers.
Those who own a compatible keyboard can take advantage of the new tech and gain the edge on their opponents through a simple firmware update. The keyboard will then be able to pair with the Razer HyperPolling Wireless Dongle.
