5. Setup the Monitoring Rectangle.
The NVIDIA Reex 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
locaon on screen where a ash or change in brightness will occur when the
le mouse buon 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 Reex Latency
Analyzer > Rectangle Locaon to adjust the locaon of the Monitoring
Rectangle.
NOTE:
• A preset locaon 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 buon.
