5. Setup the Monitoring Rectangle.
The NVIDIA Reex Latency Analyzer measures ashes 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
locaon on screen where a ash or change in brightness will occur when the
le mouse buon is pressed (e.g, placed over the muzzle of a rearm 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 Reex Latency
Analyzer > Rectangle Locaon to adjust the locaon of the Monitoring
Rectangle.
NOTE:
• A preset locaon can be chosen under Rectangle Preset.
• The Monitoring Rectangle’s size can be adjusted under Rectangle Size.
6. Now the PC + Display Latency will be able to be measured by pressing the le
mouse buon.
