• NVIDIA Reflex Latency Analyzer (only for PG259QNR)
You need to position the “Monitoring Rectangle” where there is a near
immediate change in luminance. The faster, the better. This is most often the
muzzle ash, but can be a scope change or other instantaneous movement.
This will vary by your game.
Before using this function, follow below steps to nish the monitor setup:
a. Plug in Type-B end of the USB 3.0 cable into the back of the monitor
and plug the other end into your computer.
b. Plug in the Reflex Latency Analyzer supported mouse at the back of the
monitor into the USB port closest to you when facing the display.
c. Ensure the monitor is set to G-SYNCEsportsmode.
d. Select On in the G-SYNC

the center of your screen along with the PC+DisplayLatency metric
located at the top left corner of the screen.
* PC+DisplayLatency: Enables or disables the latency analyzer

a gun muzzle flash) to change on screen during gameplay.
* MonitoringSensitivity: Adjusts the monitoring sensitivity.
* ShowMonitoringRectangle: Displays or hides the monitoring
rectangle. This rectangle specifies which pixels the G-SYNC processor
will sense during a mouse click.
* MonitoringRectanglePreset: Adjusts the default preset location for
the monitoring rectangle.
* MonitoringRectangleLocation: Manually adjusts the location of the
monitoring rectangle using the ( 5-way) button.
