Resolving connected computer issues
Use the following table to resolve connected computer issues:
Symptom Cause Solution
The connected computer’s display is
too large, too small or doesn’t
completely fill the screen. The connected computer’s video
resolution settings don’t match the
interactive flat panel’s native resolution. Set the computer’s video resolution to
3840 × 2160 at 30 Hz. (If the connected
computer can’t support this resolution,
consider 1920 × 1080 at 60 Hz as an
alternative.)
The connected computer’s screen
resolution is correct, but the image is
surrounded by black bars. The connected computer’s video card
is underscanning the image. Turn off or adjust the
overscan/underscan feature in the
video card driver software until the
image fits the screen resolution. Refer
to the computer’s video card Help for
more information.
Select the 4K UHD option from the
video card driver’s advanced menu (if
available).
The video cable is of poor quality. Replace the video cable with a better
quality video cable.
You’re using two connected video
cables. Replace the two cables with one longer
cable.
OR
Move the computer so that it’s within a
single cable length of the
interactive flat panel.
The connected computer’s display is
unstable or unfocused. The video connection is loose. Secure the video cable to both your
computer and the interactive flat panel.
The video cable is of poor quality. Replace the video cable with a better
quality video cable.
You’re using two connected video
cables. Replace the two cables with one longer
cable.
OR
Move the computer so that it’s within a
single cable length of the
interactive flat panel.
The connected computer’s video
display card is defective. Connect a different computer to the
interactive flat panel. If this improves
the image quality, consider replacing
the video card in the original computer.
