Razer Synapse

at this point i try everything. just one week ago i bought my deathadder on amazon today im trying to turn on the dongle i did everything it just doesnt turn on, i didnt even know there was a led on it at this pint until i watch a video of how it works, updated firmware , try it on other pc, uninstalled synapse 2 times, erased on the device manager the mouse and it doesnt even popped on the pc yet , i swer i tried everything and i dont live in the usa so i cant turn it back easily i gotta pay for the turn back to what should i do 

The latest Synapse update (I had one yesterday I think) disabled the automatic profile switch for some applications. The profiles do not switch automatically for Google Chrome or VSCode, but they do work for others like Visual Studio or some games.I tried everything that was suggested in some support threads regarding the faulty profiles switch (there are lots of them apparently, meaning Synapse is quite buggy).Razer, please debug the latest release or give me a link to an older version of Synapse 4.

I tested.## SummaryI have identified a fully reproducible regression in Synapse 4 affecting both the Tartarus V2 and Tartarus Pro.When the D-Pad is configured as **8-Way**, pressing any D-Pad direction while **HyperShift** is active causes the D-Pad to ignore its configured bindings and instead generate the default Arrow Key inputs.This issue does **not** occur when the D-Pad is configured as **4-Way**.The exact same hardware and workflow worked correctly in Synapse 3.---## Environment* Windows 11* Synapse Version: **4.0. [removed by moderator] *** Guest Mode (not signed in to a Razer account)* Clean installation using the official Razer Driver Clean-up Tool* Default profile only (no imported or cloud-synchronized profiles)Devices tested:* Tartarus V2* Tartarus ProThe issue is reproducible on both devices.---## Steps to Reproduce1. Install Synapse 4.2. Launch Synapse in Guest Mode.3. Configure the D-Pad as **8-Way**.4. Set **every D-Pad direction** on both the Normal layer and the Hype

Please add support for the Razer Orochi v2 on Razer Synapse for Mac. I would love to be able to control my mouse on my Mac. It would really help me with playing GeForce Now and other games that I need to use the high dpi and other settings that are only available in Synapse like Hypershift.

Now can switch ANC on/off or ambient, but cannot adjust ANC level in Synapse 4 version 4.0.86.2601160905 and beta version 4.0.86.2511170410.Synapse 3 and Audio app are correctly. Since 02-Nov-2024, I reported this issue to Razer Support staff.By the way, last month (10-Dec-2025) Razer Support staff replied me that they tried to fixed.What are Razer doing?

As the title says, the Chroma Visualizer keeps turning off automatically when I boot my computer back up, which makes me go to the Chroma App and activate it every time I use my system. I also tried reinstalling both the Chroma app and the Synapse app to no avail. If anybody has a fix to this I would be very glad.Thank you in advance.

Hello Razer team,As the title stated "Razer Chroma Visualizer not loading after Windows 11 starts". Here are the steps that I have taken in particular order.Uninstall Synapse 4 and Chroma software. Use a cleaner. Restarted/logged into Windows 11. Reinstalled Synapse 4 along with Chroma. Restarted/logged into Windows 11. Logged into the Razer app. Enabled Chroma Visualizer. Restarted/logged into Windows 11. Chroma does not start after Windows 11 login. Uninstalled Synapse 4 and Chroma. Use a cleaner. Restarted/logged into Windows 11. Installed Synapse 3 w/Chroma Sidenote/from my point of view. Synapse 3 sees Chroma as part of it's software and is able to launch decently after logging in. But Synapse 4 seems to treat Chroma as a separate software. Restarted/logged into Windows 11. Chroma works perfectly after logging into Windows 11.Only issue found, is that Synapse 3 does not seem to recognize Barracuda X Chroma is powered on.

I’ve been using Synapses since back in 2012 when it was 2 & used it all the way up to the point when it was no longer being supported & you had to use 3 or 4.one the features that 2 had was that if you had multiple programs open & you had a profile for each program, that as you clicked over to the other program, Synapse would recognise that you clicked over to a different program & automatically switch the profile over, it even displayed in green text in the lower right corner of your primary monitor the program it just switched over to. using 4, there doesn’t seem to be any such functionality or any setting to do that (or is there, i’m i’m just missing it?)It is getting old having to manually switch back & forth, every few minutes, if there is this setting, can someone please provide instructions on where this setting is… but if the function is currently not available in 4, can you dev’s please put it back?

I`ve seen a lot of threads here about broken mute button and that synapse is doing it. In my situation i installed only Razer Chroma for my Barracuda X Chroma, and this app is breaking mute button too. After pressing mic sensivity drops to 0 and not returning to normal.And by the way, why all RGB products (well, at least Barracuda X Chroma) dont have its own memory to remeber which lightning profile it is using? Or i dont know something?

1). I can't have mouse profiles on any of those open razer UI's, how to get there ?2) .. when you will support Linux customers as the first class citizens  ? .. or we should be paying for forever for our heresy to choose something better than Microsoft thing ?.

pls help, my installer doesnt even work, like it doesnt even install the app, everytime i click on the installer it just doesnt do anything

When I open chroma and try to customize it doesn’t work, when I select and try to click a color, it has prohibited/ no entry sign.

For a while now Razer Synapse 4 was working great and I had no issues with it but today I opened it and it started to crash over and over a few seconds after opening - at one point it looked like it was going to try to install an update but then it said installation failed and crashed. I tried restarting my laptop and also uninstalling synapse and going to the website to download the latest version of the installer and reinstalling it but this also failed. I am running on a razer blade 18 (2024) with rtx4090 and intel core i9 14900hx on windows 11 latest udate

Hi, i am unable to disable auto-updates. In the old razer snypase, there was a setting for me to disable this, however, in this new razer synapse 4, I am unable to do so. When I open the settings, there is no option for me to disable auto updates. I have attached a screenshot below  

I’ve got Asus Vivobook laptop, Windows 11 and Synapse 4 installed.Almost everything was just fine until one of the Windows updates.Sound became crackling, distorted with unstable loudness levels.I’ve tried everything, have texted to support: they just said that my earphones were faulty so I got to return them on warranty… I did it, got a new pair and..The issue is still there.Whenever I turn off “Turn on audio enhanements” in Windows settings the problem dissapears along with better sound, eq and stuff. So it’s not an option.So I tried the following:removed everything with razer tool installed synapse 3 instead of synapse 4Everything WORKS JUST FINE.Installed Synapse 4Issue came back.Also I’ve reinstalled every sound and chipset driver in System, manually clean registry and still no results.Seems like Razer Software can’t work properly with Windows up to date.!!!Please find the solution!!!Razer 3 now is almost obsolete….I really like Blackshark v2 Pro but geez… Your software in a night

Why can’t I add a mouse sensitivity stage?In Synapse 3, I could add as many sensitivity stages as I liked. There was a button to add another one, and it worked great.I went to add a stage to the profile I use for FPS games (as there was only 2) and all I could do was re-arrange them. That’s pretty pointless. If I add a new profile there’s 5 stages shown but, again, no option to add any.Why is this software consistently annoying me when I want to do something. There’s so many things that should be easy to do (e.g., create a macro to change active profile on multiple devices at the same time) that are just infuriatingly impossible.Synapse 4 is definitely a step backwards in terms of usability. Half the time it doesn’t event register my mouse/keyboard/Tartarus Pro unless I stop and restart all Razer apps. Even then it’s a 50/50 chance of things working properly

The Razer Synapse 4 app just bugs out when attempting to configure the Razer Pro Type Ergo Keyboard’s programmable knob (right knob). You click any of the settings and immediately the software’s interface wipes all elements on the screen but the background color which is gray. See attached. I am in a Windows 11 environment, have tried uninstalling, running the razer driver cleanup tool, reinstalling 4 times with the same issue. Also yes, the Ergo keyboard is running the latest up to date firmware.Are owners of this keyboard able to reproduce? Thanks,  

Before upgrading to Razer Synapse 4, I could hold the volume up button to increase the volume continuously. Now I have to keep pressing it repeatedly. However, when I close the Razer Synapse app, holding the button works normally again.Is there a way to keep the app open and still be able to hold the volume up button to increase the volume, without having to spam the button?

Does anyone elses keys mapped to volume not change the volume more than one step when you hold it down? This only happened recently, which im assuming is from the update and it doesnt occur when using a saved profile when synapse is closed

When I turn on my PC every time and I open razer synapse, the program doesn’t detect my Razer Blackshark V3 unless I unplug and then plug back in the USB dongle. What should I do? 

My issue is very similar to the one in this thread as in that there is no light on the Basilisk V3 but on my keyboard, the blackwidow v4 the rgb works fine. I have attempted to follow the same reinstall instructions but to no avail

The cooling pad does not work after the firmware update. Only the red light blinks, it doesn't check the temperature, and it doesn't work at all. I deleted and reinstalled Synapse 4 and even formatted the PC. What on earth was this update for? Please take quick action.

I can't add any games to Linked Games. The games are visible in the list (under the + button), but nothing happens when I click the "ADD" button. When I find the game (exe file) myself using "Browse", nothing happens either.This feature is essential and if you have multiple profiles, you can't set anything up automatically!Does anyone have the same problem?Can anyone help?Thank youOperating System: Windows 11 Pro 24H2 (build: 26100.3194)Razer Synapse: 4.0.86.2502180127Connected hardware: Huntsman Elite, Naga Pro, Mouse Dock Chroma
