Screen flickering There are some
noticeable flickering
in the displayed
pictures
• Use the native resolution of your
monitor (2560 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.
