• Use the native resolution of your
monitor (1920 x 1080 at 60 Hz) or
higher refresh rate.

your computer is turned on, turn off
variable refresh rate (VRR) through
the computer graphics setting.
•If the NVIDIA ULMB of your device
is turned on, turn off NVIDIA ULMB
by performing Factory Reset.
• If you are using an NVIDIA graphics
card and G-SYNC is turned on, turn
off G-SYNC.
• If you are using an AMD graphics
card and FreeSync is turned on, turn
off FreeSync.
• Update the graphics card driver and
firmware to the latest version.
• Change the cable connecting the
monitor to the system. A defective

Electromagnetic fields can cause
screen flickering. If there is another
device plugged into the same power
strip as the monitor, try to remove it.
