Vanadiel Posted October 13, 2020 Share Posted October 13, 2020 I am not able to change the brightness using iCUE 3.34.161 on a Dark Core RGB Pro under device settings (In iCUE). If I slide the slider it either goes completely off or stays completely on. The slider also goes all the way to the right when it's completely on, or completely to the left when it's completely off. the 50% mark on the slider seems to be the point where it switches from on to off. I was expecting to use the slider and slide it to where I wanted the brightness to be, and leave it like that. Mouse is connected using USB cable, but it also has the same issue when connected wirelessly. Link to comment Share on other sites More sharing options...
Corsair Employee Corsair Blade Posted October 15, 2020 Corsair Employee Share Posted October 15, 2020 Hi Vanadiel, I haven't personally heard of that issue happening yet with 3.34, so this is potentially a newly discovered bug. We recommend you downgrade temporarily to test if this solves the issue. Please perform a clean install using the 2 links below: https://help.corsair.com/hc/en-us/articles/360025166712-Perform-a-clean-reinstallation-of-the-Corsair-Utility-Engine-iCUE- https://downloads.corsair.com/Files/CUE/iCUESetup_3.33.80_release.msi Link to comment Share on other sites More sharing options...

Vanadiel Posted October 17, 2020 Author Share Posted October 17, 2020 (edited) Installed the older version, same problem. Also did a reboot after installation just to double check. Same issue with the slider. I am wondering, could it be a conflict with another piece of software that controls the lighting functions of the keyboard (from another manufacturer)?

LucioBP Posted February 10, 2021 Share Posted February 10, 2021 Installed the older version, same problem. Also did a reboot after installation just to double check. Same issue with the slider. I am wondering, could it be a conflict with another piece of software that controls the lighting functions of the keyboard (from another manufacturer)? I tried with old versions and with the last to 2021: - iCUE 3.37.140 - Dark Core RGB (key 1.2.55 / wireless 1.0.82 / version 1.1.164) Is there not a fix yet to decrease the brightness with the slider? Regards! Link to comment Share on other sites More sharing options...
LeDoyen Posted February 10, 2021 Share Posted February 10, 2021 as a workaround you can add a static color effect on the mouse on top of the list, set it to black and play with the opacity slider to decrease the brightness. That should get you by while waiting for a fix Link to comment Share on other sites More sharing options...
FOR Posted March 22, 2021 Share Posted March 22, 2021 Bought a Dark Core SE in Nov 2020 and also have the same issue. Brightness control behaves digital on/off but iCUE software uses a slider control which makes no sense me. I wrote Corsair support about the problem they told me to make a clean install. Maybe just a bot reply. I'm disappointed. Even a clean install of latest iCUE 4.9.350 doesn't fix it. Link to comment Share on other sites More sharing options...

aradeth Posted June 18, 2021 Share Posted June 18, 2021 Hi, is the brightness slider issue still persist? Only on/off? Link to comment Share on other sites More sharing options...
Corsair Employee Corsair Blade Posted June 19, 2021 Corsair Employee Share Posted June 19, 2021 On review of this situation, it turns out this action/performance is within the design specifications for that mouse. I will forward this feedback from all of you to the mouse specialist for review to add varying brightness slider functionality. Link to comment Share on other sites More sharing options...
aradeth Posted June 19, 2021 Share Posted June 19, 2021 Thank you for your reply and effort. Brightness slider is a must have for a wireless mouse for better battery life. Link to comment Share on other sites More sharing options...

KMBakPL Posted October 20, 2022 Share Posted October 20, 2022 (edited) More then one year and Corsair still didnt solve this stupid problem that kills battery life... I switched from Logitech becasue I thougt that overall quality (soft + hardware) is better on Corsair side. And it's not. Lot of stupid errors, unsolved bugs.. Im getting tired of these...

c-attack Posted October 20, 2022 Share Posted October 20, 2022 One way to work around this is to either: a) turn down the color values on effects to reduce brightness; or b) create a shade. To do this, add a static black (0,0,0) layer on top of the preferred lighting effect. Then use the opacity slide for the static black to let some of the underlying light pass through. This creates a 1-100 brightness slider more precise than a 3 position setting. Link to comment Share on other sites More sharing options...
mellow_jo3 Posted January 28, 2023 Share Posted January 28, 2023 Hello, you all dont know me. But i'm from the future, the year 2023. I just came to tell yall that corsair STILL HASNT fixed this problem. Just bought my mouse recently and started using it wirelessly and wanted to adjust the brightness to preserve battery obvi. Well shocker, the slider only goes from 0% to 100%. This is insane. Link to comment Share on other sites More sharing options...
