After upgrading to GeForce Experience 3.0 from 2.xx, I noticed the LED Visualizer is missing
The NVIDIA LED Visualizer is available as a standalone utility from the following URL:

Please note: The NVIDIA LED Visualizer utility does not support the GeForce RTX 20 and GeForce RTX 30 series graphics cards. For GeForce RTX users, we recommend using a software solution from one of our board partners such as EVGA Precision X1.
