GeForce GTX LED Visualizer Introduction

Several NVIDIA GeForce GTX GPUs, and the NVIDIA GeForce GTX SLI Bridge, feature illuminated LEDs that can now be controlled with the new GeForce Experience “NVIDIA GeForce GTX LED Visualizer” module. Included with all installs of GeForce Experience, the new module allows GeForce GTX users to customize the brightness and animation of the illuminated “GeForce GTX” text, adding patterns and effects that further enhance the personality of your PC. On the SLI bridge, the illumination and animation of the GeForce GTX Claw logo can be similarly controlled.

The new and very exclusive NVIDIA GeForce GTX SLI Bridge.
The ultra-desirable illuminated GeForce GTX SLI Bridge is available exclusively through the purchase of a GeForce GTX Battlebox.

To get started, all you need is GeForce Experience 1.7, included with all GeForce drivers, beginning with 331.65 WHQL. When installed, you’ll be able to use the following effects to customize your LEDs:

  • Control Animation Effects

Configure the LEDs to be turned on at a brightness level of your choosing, or to flash in a number of different patterns across multiple LEDs.

  • Monitor GPU Activity

Configure the speed of available animation patterns to correspond to a GPU activity level, such as GPU temperature, clock speed, fan speed, or utilization. If you choose a steady brightness and no flashing, then the brightness will change as the GPU activity changes.

  • Respond To Audio

Configure the LEDs to respond to audio, such as when playing games.

  • Set A GPU Activity Alarm

Configure the LEDs to act as an alarm to alert you, for example, when a GPU temperature or fan speed threshold has been reached.

  • SLI Monitor

Configure the LEDs to turn on only when SLI mode is enabled.

LED Visualizer Configuration

After you have installed GeForce Experience 1.7, the LED Visualizer module can be accessed through a dedicated tab in the application itself.

GeForce Experience NVIDIA GeForce GTX LED Visualizer - My Rig
The My Rig section of GeForce Experience gives you instant access to all of the application’s features.

Clicking the "Configure LED Visualizer" button opens the LED Visualizer module, giving you access to its configuration features.

GeForce Experience NVIDIA GeForce GTX LED Visualizer - LED Visualizer Window
The cog on the top right of the window allows you to configure whether LED effects are applied at Windows startup. If they are not, you will need to open the LED Visualizer module to activate them.

The left pane of the new LED Visualizer window gives you the option of applying identical effects to multiple GPUs and the GeForce GTX SLI Bridge simultaneously with the "All LEDs" button, or different effects to each with "Each LED".

GeForce Experience NVIDIA GeForce GTX LED Visualizer - All LEDs Mode

If you do select "Each LED", you must specify the GPU or SLI Bridge to be configured by clicking it on the graphical display below the All LED-Each LED toggle. The selected item will be highlighted and the name on the right pane changed to reflect your choice.

Configuring LED Effects

With the LED Visualizer, the LEDs on your GeForce GTX hardware can be configured in a multitude of ways, which we will now detail. For best results, we recommend the ‘Each LED’ mode, giving you greater flexibility in the range of effects you can apply.

GeForce Experience NVIDIA GeForce GTX LED Visualizer - LED Effects Dropdown

The table below details the general effect each setting has on your LEDs:

LED Effects Setting

Description

Off

LEDs are disabled.

On

LED animation is activated.

On (GPU Property Alarm)

LED animation activates whenever the specified GPU property level is met or exceeded.

On (SLI Is Enabled)

LED animation activates when SLI is enabled (requires GeForce GTX SLI bridge connector).



LED Animation Style Options

The slider to the right of the “Style” dropdown determines the frequency of the effect, or its speed, depending on the effect chosen.

GeForce Experience NVIDIA GeForce GTX LED Visualizer - Style Dropdown

The table below details each effect, and states whether the illuminated SLI Bridge is required, and whether the “All LED” setting has to be used instead of “Each LED” mode.

Animation Style

Description

SLI LED Required

“All LEDs” Required

Breathing

LED brightness changes between minimum and maximum levels with slight delays at the extremes, simulating a breathing pattern.

 

 

Audio Flashing

LED brightness flashes in sync with audio activity from the computer, such as from a media player or game.

 

 

Flashing

LED brightness smoothly changes between minimum and maximum levels.

 

 

Dual Flashing

LEDs flash twice per animation cycle.

 

 

Random

Randomly selects an animation style and alternates the selection with the breathing pattern. The entire pattern becomes: First random selection > Breathing cycle > Second random selection... etc.

 

 

Variable Brightness

Combines with the “Variation” setting to adjust the brightness of the LEDs based on GPU temperature and other options. Please note that the setting is not available if “All LEDs” is selected.

 

 

No Animation

LED brightness is steady. Use the brightness slider to determine LED brightness.

 

 

Electric

LED brightness switches quickly between minimum and maximum levels; the "quick flash" travels in a linear manner between all the LEDs.

X

Flow In

First the SLI Bridge LED brightness goes from minimum to maximum, after which all the GPU LEDs go from minimum to maximum brightness. This gives the impression of light flowing from out (SLI) to in (GPU).
