Audio or Display Problems related to HDMI on Intel® NUCs That Use LS-PCON

What are you seeing?

• Your Samsung 6000* series television doesn't display video when connected to your Intel® NUC.
• Some surround sound formats don't work when using your Intel NUC with an AV (Audio/Video) receiver.
• Head-mounted display doesn’t wake up from sleep (S3) when using Windows* Mixed Reality.
• Flickering display when using an HDMI-to-DVI adapter.
• A blurry or distorted display.

Why are you seeing it?

One reason you could be having these issues is due to old HDMI firmware for the DisplayPort 1.2a to HDMI 2.0 Level Shifter/Protocol Converter (LS-PCON) on your Intel NUC.

How to fix it

Update the HDMI firmware. If your Intel NUC isn't on this list, either it doesn't use LS-PCON or there isn't currently an HDMI firmware update available.

Troubleshooting

If you get a blank screen for longer than two or three minutes during the update, leave the HDMI device connected, connect another display to the other display output, and run the update again.
