Screen flickering There are some
noticeable
flickering in
the displayed
pictures
• Use the native resolution of your
monitor (3840 x 1600 at 60 Hz) or
higher refresh rate.
• If the variable refresh rate (VRR) of
your device is turned on, turn off
variable refresh rate (VRR).
• 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 Free-Sync is turned on, turn off
Free-Sync.
• Update the graphics card driver and
firmware to the latest version.
• Change the cable connecting the
monitor to the system. A defective
cable can cause the signal to break
while being transmitted across the
wire.
• Check the surroundings.
Electromagnetic fields can cause
screen flickering. If there is another
device plugged into the same power
strip as the monitor, try to remove it.
