NVIDIA Reflex Latency Analyzer

NVIDIA Reflex is a technology designed to reduce the input lag between your peripheral devices (e.g., mouse) and your PC/display to reduce latency and help improve your performance and in-game experience.

To use the NVIDIA Reflex Latency Analyzer:

  1. Connect the monitor, via DisplayPort, to your GeForce GPU.

    • Press the [●] key or move the joy key [◄] or [▲] or [▼] to display the On-Screen Display (OSD) Menu.
    • Using the joy key, go to: G-SYNC Processor > NVIDIA Reflex Latency Analyzer > PC + Display Latency > On.
  9. Setup the Monitoring Rectangle.
  10. The NVIDIA Reflex Latency Analyzer measures flashes or bright changes on the screen. The measurements are taken within the Monitoring Rectangle.

    To measure latency, the Monitoring Rectangle will need to be moved over a location on screen where a flash or change in brightness will occur when the left mouse button is pressed (e.g, placed over the muzzle of a firearm in an FPS game).
    In the OSD Menu:
    • Press the [●] key or move the joy key [◄] or [▲] or [▼] to display the On-Screen Display (OSD) Menu.
    • Using the joy key, go to: G-SYNC Processor > NVIDIA Reflex Latency Analyzer > Rectangle Location to adjust the location of the Monitoring Rectangle.
    NOTE:
    • A preset location can be chosen under Rectangle Preset.
    • The Monitoring Rectangle’s size can be adjusted under Rectangle Size.
  11. Now the PC + Display Latency will be able to be measured by pressing the left mouse button.

Blue Light Filter and Eye Health

The Blue Light Filter blocks high-energy blue light for a more comfortable viewing experience.

Quick Access Blue Light Filter Setup

Enabling and disabling the Blue Light Filter can be done on the fly via the Quick Access Key.

Quick Access Key
NOTE: When enabling the Blue Light Filter (BLF) via the Quick Access Key, the BLF value will be 100 which is certified by TÜV. However, the BLF value will be 0 if the user chooses another function via the Quick Access Key.

While using and enjoying your monitor please keep the following in mind:

  • Viewing computer screens for extended periods of time may cause eye irritation and discomfort. To reduce these effects, it is recommended to take periodic breaks from viewing to allow the eyes to relax.
  • Users can customize the Blue Light Filter value through the Game Modes Menu.
Blue Light Filter
  • The monitor also supports Flicker-Free, which reduces or eliminates screen flicker, thus easing potential eye strain.

Calculating Breaks

When viewing the monitor for extended periods, it is recommended to take periodic breaks from viewing. Short breaks of at least five (5) minutes are recommended after one (1) to two (2) hours of continuous viewing. Taking shorter, more frequent breaks are generally more beneficial than longer, less frequent breaks.

Looking at Distant Objects

While taking breaks, users can further reduce eye strain and dryness by focusing on objects that are further away from them.

Eye and Neck Exercises

Eye Exercises

Eye exercises can help minimize eye strain. Slowly roll your eyes to the left, right, up, and down. Repeat as many times as needed.

Neck Exercises

Neck exercises can also help minimize eye strain. Relax your arms and let them hang at your sides, bend forward slightly to stretch the neck, turn your head to the right and to the left. Repeat as many times as needed.

Quick Access

Quickly initiate some functions and modes through the Quick Access key and menu. Users can also define which functions or modes they prefer in the Quick Access Menu via the Setup Menu in OSD. The function/mode will be enabled as soon as the light-bar moves on the item, and will disable after removing the light-bar.

In the Quick Access Menu, “Return” means users can “automatically” go back to the mode they chose before entering the Quick Access Menu.

For example, if users chose “Console Speed” mode before entering the Quick Access Menu and there is an existing FPS option in the Quick Access Menu, according to the Quick Access definition, users will enable FPS mode when the light-bar moves on the item. Then, when moving the light-bar to “Return,” the mode will be changed into “Console Speed” automatically which is same as the mode before user entering the Quick Access Menu.

  1. Press the Quick Access Key to display the Quick Access Menu.
  2. Press the Quick Access Key to select your preference.
