NUC7i7BNH & 4K - Did I mess up?

Jump to solution

Recently acquired a NUC7i7BNH to fill-in as a light duty Plex server (single stream, mostly direct play).

Win10 Pro

500GB m.2 SSD

2TB HDD

Cat 5 Wired

All seems to be working except when I attempt to use the NUC as a Plex client. I get playback on my 1080p content, but a only black screen (w/audio) for 4K HDR content. The NUC can serve 4K content to my other Plex clients with no complaints (AndroidTV, LGTV, TiVo). Using the NUC as a Plex client/player is my issue. Before purchasing, I had read 4K playback was possible on these devices.

So far, here are my steps:

1. Swapped out HDMI cables, swapped to alternate HDMI Inputs to LGTV 4K TV

2. Updated BIOS to latest v1.72, dated 11/20/2017 (claims to update HDMI 2.0 Firmware)

3. Updated Graphics driver to latest v24.20.100.6025, dated 5/7/2018

Multiple reboots, confirmed the BIOS and drivers updates have "stuck", still getting blank screen with 4K content.

Questions:

1. Did I misunderstand the 4K playback capability of this device?

2. Any other BIOS/Config settings to tweak?

3. Any suggestions to get this NUC working as expected?

Thank you!

Mark

Following up:

It appears as if Intel NUC7i7 & Win10 are not the culprit here.

1. Win10 Settings > Display > Select HDR/WCG = ON - LGTV flips to HDR mode and displays the expected indicator on-screen

Even in Win10's HDR mode (noted above), Plex will not play HDR content, just HD/SDR. HDR content appears as Back Screen w/audio.

So, a Plex Media Player issue.
