Razer Synapse 4

Hi everyone,My device: Razer Blade 18 (2024) – Intel i9-14900HX / RTX 4080 / Windows 11 Home I’m having an issue where Razer Synapse doesn’t start automatically with Windows, or if it does, it launches very late after the system boots. Until Synapse finally loads, my keyboard shows random lighting effects instead of my saved Chroma profile. Here’s what I’ve already tried (without success): Enabled “Start Razer Synapse on system startup” in the settings. Checked Task Manager → Startup tab (Synapse is enabled). Made a custom Task Scheduler entry to start Synapse at login (with and without delay). Set Synapse to run as administrator. Verified that Razer Synapse Service and Razer Central Service are set to “Automatic” and running. Reinstalled Synapse completely (including deleting leftover Razer folders from AppData and Program Files). Despite all this, Sy

im on firmware 1.0.2.0 and my sidetone has a really annoying delay and it sounds badhas anyone found a fix?ive tried things other people tried on different headsets but nothing worked

For many years in synapse 3 I had Excel linked to special profile. After migrating to synapse 4 few months ago I was unable to do so, so had to roll back to S3. Now, few weeks ago I tried S4 again and it worked this time. But today it stopped working. In the linked games tab excel was shown with comment "game not found". I deleted it from the list and tried to re-add it. For some reason when I choose Excel.exe with "brose" menu nothing happens, and it returns to the menu of linked games.That is very frustrating for me, since Excel profile is the most important function in synapse for me.

Blackwidow V4 Pro and Synapse 4 installed.If Synapse is running and I run other certain apps, like a music streaming app, multimedia keys don’t work there and volume control stops working. As soon as I exit the music streaming app, volume control shows up reacting to the roll bar with significant delay. But sometimes it stops working at all. Only if I exit Synapse, it’ll be working.I tried all the steps proposed by support documentation, like rei-installation of the keyboard driver, Windows update and clean re-installation of Synapse, but they didn’t work.

Hello. I bought the Kraken V4 X headset. Now I've set everything up and THX spatial audio is working fine, but when I look in BF6 and in the app, I can only select Stereo or THX spatial audio as my profile.But BF6 has other profiles. How can I activate them?

I am using the Razer Blackwidow V4 low-profile TKL keyboard and the Synapse 4 software. When I try to allocate the hypershift-function to a custom key the hypershift option does not appear (I have seen videos on YouTube with other keyboard, where the hypershift option (arrow) appears when clicking on a custom key). So right now, the only way to activate Hypershift is the FN key, which is too far away for my purposes. I want to use the CapsLock key to trigger hypershift. Can we expect to get this functionality in future Synapse and/or keyboard firmware updates? This is actually an essential function I need to have using this keyboard.

Hypershift still does not work on Synapse 4 for my Deathadder V3 pro. It does work on my Huntsman kayboard. The only way to make it work on my mouse is to close down synapse completely then it starts to work again. I’ve been reporting this for around a year now please get it sorted or I will be forced to switch eco systems where I know the features I need work properly.

Hi.Probably all know that macro on synapse 4 not working the same as in synapse 3.I just created support ticket and report an issue, this will be probably the most curved road but maybe I will handle that.I notice that macro from synapse 3 moved to synapse 4 is played once even if option is set “play while assigned key is pressed”There is an option to set a loop for but if I add this option I give a information in synapse 4 that’s it required razer synapse…I have walkaround but it’s impacting on lighting on all your razer devices which might be dangerous for them.When I have installed both synapses - 3 and 4, Im able to use macro from synapse 3 and lighting from synapse 4 but there is some sort of glitch on the lighting, its turning off for a second randomly. If someone will use this walkaround you are using on your own risk.I will update the thread when I will have some information from

The THX Game Profiles just don’t work at all, first there’s no games or apps recognized automatically, second when I try to add a executable and confirm it literally does nothing a the list continues empty, I just upgraded to windows 11 and the issue also happened in windows 10, so reinstalling synapse don’t work, pls help

Hello all, Since using synapse 4 I've got some troubles with my profiles for minecraft Java. Normaly I add the Java file in my games and it works. But with synapse 4 it delete it from the game list after every boot of minecraft and when it doesn't delete it it put it graued out saying it doesn't find it.  Is there another way or do I have to roll back to synapse 3? Thanks in advance

The mouse is getting shown and I can create macros but as soon as i want to change the aktions of the Buttons the Page turns gray and I cant do anything 

I know it may seem like a small thing however the ability to change the trigger dead zones seems like a much needed feature that has been implemented before in the past. I don’t like using the mouse click triggers but I also need to have fast actuation on the triggers. $30 controllers on Amazon have it so why not this $120 controller? It literally has everything else I want and need except the ability to adjust the LT/RT trigger deadzones, which seems like an easy software update to implement.

Hello!I’m having a problem switching profiles on my mouse (Naga v2 pro) when I’m connected to my dock pro.Everything works fine when I use an USB cable, but when I try switching profiles on wireless (2.4), Synapse is switching profiles alright, but my mouse is still “stuck” on the last profile (or even on default key mapping sometimes)I found this 2 years old post: It looks like it’s a similar issue.Any idea how to fix this? I’ve already tried to uninstall a bunch of times, with and without the chroma app but nothing worked…Thank you, have a lovely day_edit / Solution:I finally got it to work! If anyone needs this, here is what I’ve done:Uninstall Synapse 4 and completely wipe out files and registry entries with revo uninstaller (make a re

My rgb doesn't load at system startup. The Synapse 4 and Chroma software ARE running as per settings to run at system startup, and verified with a quick glance at the processes tab in Windows Task Manager.The rgb only loads..when I open ANY Razer software, be it Synapse or Chroma.I have uninstalled and reinstalled the COMPLETE software suite and endured the resultant fiasco of getting everything set back up rgb and scroll wheel tension wise.  ..what in the name of that warm place where bad people go have they done

there are no notifications about switching profiles in games, but everything is displayed manually. Has anyone encountered this?

I don't get Battlefield 6 thx game mode at all 

I apologize if I write wrong or if the section where I write is wrong but I need to know...I would like to know why the RGB immersive mode does not work in Synapse 4 for supported games such as Apex or Overwatch. In Synapse 3, I just had to start the game to have customization of the effects on all my Razer components. Things that don't happen on Synapse 4, why? I'm not talking about custom profiles but about lighting effects created by Razer for games like Apex or Overwatch like an effect on the keyboard when you die or when you load an ultimate on a character,I would like to know if there is anyone who knows how to activate them or if they are not present on synapse 4 thanks to those who will help me

This is the 10000th time I install a new synapse 4 update. I use the provided migration tool to migrate my color profiles from Synapse 3 which works perfectly on my Razor 18 system. However, as always, the migrated profiles simply cannot be loaded into the chroma app, so I have no way of restoring my Synapse 3 color profiles for my Mouse and Keyboard. I am so disappointed with Razor. right now. None of my previous posts have been acknowledged.  Revertin to Synapse 3 once again where everything works perfectly.  

I recently just purchased the Wolverine v3 Pro 8K and it’s been my go to controller ever since I switched from the Scuf Envision Pro. However, one thing I miss about the Scuf is the fact that I can map scroll wheel up or down to any button. Is there a chance that you can add mouse buttons to Synapse in the future so I can get scroll wheel back?

I think I've tried every blog post and suggestion, but I still can't see my Razer Cobra Pro mouse in Synapse. The problem is that the mouse doesn't show up in Synapse, but it does light up as a third-party device on Chroma, but I can't change the colors. I've deleted the device from Device Manager hundreds of times, deleted and reinstalled apps hundreds of times, but it still doesn't work. Is there a solution?

I just cannot fight version 4 anymore, its absolute trash. Went back to 3 and will deal with any issues after Jan. 20th 2026 or just replace all my gear.

Dear Razer,I have been your customer for at least 15 years, give or take. It started with mice, then keyboards, then headsets. Now I have all of the above-mentioned products and more from you. Until recently, I was also rocking the O11 Dynamic Razer Edition. I have always defended your software, as I NEVER had issues with Synapse 3 and only minor troubles with Synapse 4.To the matter at hand. On my older system, I started to encounter issues with Synapse 4 that I could not resolve. But alas, this system will be sold, and the new owner will have different peripherals. I built a completely new system, installed Windows 11, and proceeded to install all the necessary software. On the freshly built and newly installed system, Synapse 4 failed to recognize my Cobra Pro. The mouse was working, but the software could not detect it. Unplugging the USB-C from the docking station helped, but I do not want to do that every single day. Once the mouse was recognized

Hi,I’m using the Razer BlackShark V2 Pro. When I adjust my microphone settings through Synapse, the sound quality is great and background noise is filtered out. However, these settings are not applying outside of Synapse’s own mic test. In Discord, Windows Sound Control Panel, or any other software, the mic sounds unfiltered and background noise (like keyboard sounds) comes through. It feels like Synapse settings are not being applied at all. I already tried different USB ports, updated drivers, and even reinstalled Synapse, but the issue persists. Things I have already tried: Updating, resetting, and reapplying drivers (currently on the newest available: 2.6.11 Headset / 2.4.1 Dongle) Installing different Synapse versions Uninstalling drivers from Windows and letting them reinstall Testing all kinds of micro
