GPU is detected in SignalRGB but RGB on GPU cannot be controlled e.g. changing colour, effect, pulsing etc has no effect.
Some things I’ve tried:
- Power cycle
- Updated chipset & BIOS
- Updated GPU driver
SignalRGB version is 2.5.55 on Windows 11. Gigabyte Gaming OC 5080 16GB on a Gigabyte X870E Aorus Elite Wifi 7 Mobo.
