Blackwidow pro v4 colors won't change

Same here my friend.  This is clearly not a one-off situation.  I suspect the latest Synapse drivers broke it, because it WAS working just prior to a recent update.  Hopefully Razer fixes it soon; it’s super annoying.

Maybe if we keep replying it will get some attention :)

I think you are right as I installed a 2 week backup of my system and it works again!

Hear that Razer?  You probably want to do an EMERGENCY UPDATE for this problem.  Anyone that buys a Blackwidow V4 Pro will probably think it’s broken and return it, or worse give bad reviews.

I’m having this problem and Synapse 3 20230712 doesn’t fix it.  My RGB’s only ever worked without Synapse running since I’ve had it only a few days.

same here too. Close out of Synapse and the colors will change but obviously never sync with other gear. Also, the volume rocker doesn’t work when Synapse is working. Come on Razer, please fix!!!!

I have a tech support ticket out to Razer, after several back and forth things I believe they’ve now said it’s some kind of conflict with a Windows update or something.  They are no longer asking questions it’s now in “we are working on it” phase.  

3 weeks and no fix yet. I have a ridiculously expensive RGB keyboard that only does B

I’d try with external app like OpenRGB. But if it fails changing color on this app too - then only keyboard RMA.

Does OpenRGB allow color synchronization with the other devices?

Yes, it should sync RGB with other devices.

I normally use SignalRGB but they removed the plugin for this keyboard due to issues of its own. The keyboard itself is fine it’s supposedly a software issue.

Tried OpenRGB and it doesn’t have any support for the v4 Pro at all, currently only goes to v3.

Without Synapse running the keyboard cycles through it’s colours as normal so I know it’s capable of it.

The Blackwidow v4 RGB works just fine when Synapse is not running and fn+ctrl+(1-9) will change the lights.  This doesn’t help at all if you want multiple RGB devices synchronized using Synapse.  It really seems to be software and not hardware as the point of failure.  Some folks said their RGB worked fine until a Synapse update a few weeks ago.  I haven’t had mine that long, so the RGB has always been white unless I stop Synapse and fn+ctrl+(1-9) to something other than just white.

Mine is exactly the same, only brought the keyboard yesterday so have never seen it work properly yet.

I traced my problem down to Windows insider versions. Any update after 22H2, OS Build 23481.1000, Feature Pack 1000.23481.1000.0 does not let Synapse change the keyboard colors, dated 6/15. Not sure if they changed a driver or not

I was wondering about that because my desktop has an insider build but my laptop does not. And it’s working fine on my laptop. 

@Razer.Zionzedd - could you look at the issue? Thank you ;)

I think 

I’m pretty sure that is my problem.  My Windows is Version 22H2 23506.1000.  Synapse changes the colors just fine on my non-preview version of Windows. For some reason I clicked to install the Dev previews but when I did the option to set it back to normal was immediately disabled.  A few weeks ago, I queued it for unenrollment, but I have no idea how long until that happens.  I did this to myself.  I miss Save and Cancel buttons. 😒

In case it comes up, Windows Version 22H2 23511 does not solve the problem.  I didn’t try a clean reinstall of Synapse after the Windows update today.

You should be able to use go back to a previous version in system recovery without resetting the whole pc, never should have picked the dev insider builds

Don’t waste your time reinstalling synapse it won’t work, it also takes forever to reinstall

Interesting.  I’m also running the Windows Preview build.  Is that the true source of this problem?

If it is, I hope rolling back will fix the issue… however, I am concerned that once this “preview build” gets promoted to a public build, it’s going to break all the normal Windows users as well.

Razer has given up on my case.  They said “We can’t reproduce it”. They probably aren’t using Windows Preview builds.  I’ll try to get rid of the preview build tonight and see if that fixes it.  Preview build has been annoying me anyway, takes forever to update when there is an update.

I’ll report back if that fixes it.

The latest version of synapse dated July 31 has fixed the problem finally

I just did a “clean” install of Synapse 3 but I still can’t change the light color and pattern.  Good news is, at least the lights are on so I can read the keys.  As of earlier this week, I started running Windows 22H2 Build 23516.1000 due to a Windows Update.  I may have to wait for MS to get me on the general release.

I just installed 23516.1000 and it no longer works again :(
