Possible solutions
• Adjust the environment lighting condition.
• Ensure the monitor is setup at a well-lighted
environment, preferably under ceiling lights. The
user should avoid a dim / dark background. The
user should avoid direct facing a window with
bright sunlight.
• Alternatively, you may use Dell Peripheral
Manager to adjust the webcam setting of color.
• Adjust the environment lighting condition.
Ensure the monitor is setup at a well lighted
environment, preferably under ceiling lights. The
user should avoid a dim environment.
• Use a clean and slightly damp cloth to wipe the
surface of the front webcam.
• Adjust the distance between the user and the
camera. The user should avoid sitting too far
away from the camera. The most optimum
distance between the user and the camera is
70 cm.
• This is normal behavior as the volume
specifications are different between Teams and
Zoom.
• This is normal behavior. The resolution of the
small images are compressed when the main
image is in high resolution (4K). If a lower
resolution (720P & 1080P) is selected, there will
not be any difference between the images.
Always poor:
• Check that your computer is USB 3.0-capable.
• Some computers have USB 3.0, USB 2.0, and
USB 1.1 ports. Ensure that the correct USB port
is used.
Sometime poor:
• Network will affect the image quality, ensure
your network is fine.
