[LCD Monitor] When turning off the screen or when there is no HDMI/Display signal, a noticeable fan noise can be heard from inside the screen.

Model:PG27UQ/PG35VQ/PG65UQ/PG32UQX/PG27AQN

When you turn off the screen and press the power button, the fan will continue to run. This design is to protect the G-Sync module and ensure that it will not be damaged due to overheating during operation. Even when the screen is turned off, the G-Sync module is still in operation, so the fan is needed to maintain its stability. Although this may cause some noise, it is necessary to ensure the operation and longevity of the G-Sync module.

To turn off the fan, please enter ”Deep sleep” or”Power Saving” mode. The steps to set it up are as follows:
