8K Picture Quality
• For streaming services that support 8K resolution,
check with the content provider for network
bandwidth requirements to support 8K resolution
streaming.
• For devices like game consoles and computer
graphics cards that are capable of supporting 8K
resolution, make sure the device has the latest
software that supports 8K resolution output and
make sure that the game title or program is also
capable of supporting 8K resolution.

•
When connecting to devices that support 8K
resolution output, make sure to use an HDMI
cable that is marked as a certified “Ultra High
Speed HDMI Cable”. Older HDMI cables are not
capable of supporting 8K resolution, so only the
latest ultra high speed HDMI cables are required
to support 8K or even 4K / 120Hz.

• Select the correct wireless network name and
verify the password entered (case sensitive).

for more than 2 minutes and reconnect.
