Razer is expanding the availability of its 4000 Hz HyperPolling technology, bringing a feature previously only available on the BlackWidow V4 Pro 75% to other models in the BlackWidow range. This reduces wireless input lag to a theoretical minimum of just 0.25 milliseconds – a decisive advantage for anyone who values lightning-fast response times and maximum control.
- Up to four times faster polling rate than the industry standard
- Supported by the Razer HyperPolling Wireless Dongle
- Compatible with selected BlackWidow V4 keyboards
- Activation possible via firmware update and Synapse 4
What is behind 4000 Hz Wireless HyperPolling?
While most gaming keyboards work with a polling rate of 1000 Hz, Razer goes a decisive step further with 4000 Hz. This means that the keyboard transmits four times as many signals per second to the PC. In practice, this results in a noticeably lower latency of just 0.25 ms.

Especially in competitive gaming, where milliseconds make the difference between winning and losing, this technology offers a clear advantage. Razer combines this with its in-house HyperSpeed wireless technology to ensure a stable and extremely fast wireless connection. The company is once again setting new standards in the field of wireless gaming peripherals.
New models with high-speed support
The following keyboards now also benefit from 4000 Hz wireless technology:
- Razer BlackWidow V4 Tenkeyless HyperSpeed
- Razer BlackWidow V4 Low-profile HyperSpeed
- Razer BlackWidow V4 Low-profile Tenkeyless HyperSpeed (our test)
These models cover different requirements – from more compact tenkeyless designs to particularly flat low-profile variants. Razer is thus expanding the range of gamers who have access to this cutting-edge technology and appeals to both e-sports enthusiasts and users who value slimmer keyboards.
Simple activation via Synapse 4
A firmware update via Razer Synapse 4 is required to take advantage of the full performance. Users simply need to install the latest software version, pair their keyboard and activate the option in the “HyperPolling Wireless Dongle” tab. The process is deliberately streamlined and allows even less tech-savvy gamers to activate the feature quickly.
Synapse also checks compatibility and automatically updates the firmware of both the keyboard and the dongle if necessary. In this way, Razer ensures that all components are optimally coordinated and that the 4000 Hz polling works without any problems.
Conclusion
With the expansion of the 4000 Hz HyperPolling technology, Razer is introducing an innovation that will attract attention, especially in competitive gaming. Shorter response times, higher precision and wireless stability set a new standard for wireless keyboards.
The supported BlackWidow V4 models are available now. The HyperPolling Wireless Dongle is sold separately and can be used with compatible keyboards to realize the full potential of 4000 Hz technology.
