Blackwidow v4 pro not appearing in chroma studio even though it's detected as a device in chroma.

I have a blade 16 2025, I’m using a black widow v4 pro with it but the black widow doesn't appear as a device in chroma studio. I have windows dynamic lighting disabled for all devices in windows settings. Keyboard is plugged in via USB directly to laptop (no hub), I have latest firmware for the black widow (v1.05 released in January of this year). and latest razer apps.

I’ve tried uninstalling all apps and re-installing, resetting the keyboard via caps and esc mechanism but no luck.

One thing I’ve noticed is that when when I change synapse lighting settings from “RGB” to “dynamic” then the black widow keyboard appears in the chroma studio, as soon as I switch the settings back to “RGB” in synapse it disappears again. All other razer devices appear in studio (blade 16, basilisk mouse, Goliath mouse pad) without issue. So it seems to be just the black widow v4 pro having trouble being detected when RGB is enabled.

Hi Burgundysitefront365

 

The behavior you are experiencing is due to an active conflict between Windows 11's HID LampArray integration and Razer's Chroma engine within the new Razer Synapse platform. When set to "RGB" mode, Synapse attempts to claim exclusive low-level hardware control over the BlackWidow V4 Pro's LEDs, but a hidden Windows driver state blocks it, causing the device to drop out of Chroma Studio. Flipping it to "Dynamic" hands the control over to the Windows implementation, which makes it visible under that specific API path.

Because you have already performed standard software reinstalls, firmware updates, and keyboard hardware resets, you need to strip away the underlying Windows driver references and override the device configuration cache. To give you a clear roadmap, PM me both of your Razer Blade 16 2025 and BlackWidow V4 Pro  SN: (Follow steps here: https://mysupport.razer.com/app/answers/detail/a_id/548/~/how-to-find-the-serial%2C-product%2C-or-part-number-on-a-razer-device) and link of your receipt in a PDF format: (Save the shareable files via any online drive account listed here: https://mysupport.razer.com/app/answers/detail/a_id/4011?_ga=2.197232171.544708261.1744067200-1885068520.1744067200&_gl=1*vo487o*_ga_3TRK53PM75*MTc0NDA2NzE5OS4xLjEuMTc0NDA2NzM0My4yNC4wLjA).
