Troubleshooting
4K Ultra HD Picture Quality
Having trouble completing the guided setup? Don’t worry, it’s usually an easy fix.
• 4K Ultra HD picture quality is largely
dependent on the source. Make sure your
source content is 4K UHD.
• To stream 4K Ultra HD content, we
recommend a broadband speed of 16 Mbps
or more for optimum viewing.
• For Cable, Satellite, Gaming Consoles, and
Blu-Ray players, we recommend using
“High-Speed HDMI cables.”
Cannot connect to wireless network
• Select the correct wireless network name and
verify the password entered (case sensitive).
• Relocate the router from objects that interfere
with performance (cordless phones, baby
monitors, etc. ).
• Reboot the router by disconnecting the power
for more than 2 minutes and reconnect.
