Screen flickering There are some
noticeable flickering
in the displayed
pictures
• Use the native resolution of your
monitor (3440 x 1440 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 computer. 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.
