30. Symptoms, Possible Causes and Solutions

Below are different symptoms that might be encountered as the Planar UltraRes L Series
display is installed. First look at the different symptom descriptions for the issue. Then look at
the possible cause and try the suggested solution(s). If the solution does not resolve the issue,
please contact Planar's Technical Support Department.

30.1 Symptom: Display Doesn't Respond to External Control System

Solution
Confirm the Power Down Mode setting. Networked standby or Fast Startup are required to
enable the use of external control devices. Standby disables all external control except IR,
allowing the display to be in the lowest power setting. See "Power Down Mode" on page 90.

30.2 Symptom: Can't Get PC to Output 4K @ 24/30/60 Hz

Solution
Confirm that DisplayPort-to-HDMI adapters are not being used. These adapters do not support
outputting 4K content.
Solution
Ensure a high-speed HDMI or a Certified Premium HDMI cable is being used. Standard HDMI
cables might work but are not guaranteed.
Solution
Verify that the selected EDID Type setting in the OSD is 4K60 or 4K30. If the EDID setting is
changed, the cable may need to be disconnected and reconnected.
Solution
When using 4K @ 60 Hz on HDMI, the display must be connected to HDMI 1 or HDMI 2.
Solution
When using 4K @ 60 Hz on HDMI 1 or HDMI 2, the Multi-Source View setting must be Single.
