Symptom: Can’t Get PC to Output 4K @ 24/30/60 Hz
Solution
Make sure that your graphics card can support a 4K output. See "Supported Graphics
Cards" on page 25 for a list of the current graphics cards that Planar supports for the
Planar UltraRes Series displays.
Solution
Confirm that you are using a DisplayPort output. You can’t use a DisplayPort-to-HDMI
adapter to output 4K content.
Solution
Make sure you are using a high-speed HDMI cable. 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 you change
the EDID setting, you may need to disconnect and reconnect the cable.
Solution
If you are trying to use 4K @ 60 Hz on HDMI, the display must be connected to
HDMI 1 or HDMI 2.
Solution
If you are trying to display 4K @ 60 Hz on HDMI 1 or HDMI 2, the Multi-Source View
setting must be Single.
