DR HDMI 8K user manual, chapter by chapter

The unit in one chapter: an HDMI 2.1 repeater for 1500MHz / 48Gbps signals, its EDID control, and the choice between rotary switch, browser and network commands.

Which cable goes where (USB-C power, HDMI IN, HDMI OUT, RJ45) and why a 1500MHz / 48Gbps link needs a certified or tested 8K cable.

The OLED start-up screen, the default, RX EDID, TX EDID and unit info pages, and how the rotary switch moves between them.

Opening the browser interface by IP address, hostname or mDNS, reading the header fields, and getting back in after a wrong static IP.

The MAIN page field by field: signal, TMDS/FRL and lane readouts, sink and source EDID details, the three EDID modes and every flag.

All 100 EDID tables by number: ten custom-default display profiles, then 90 presets from 8K60 4:2:0 FRL-5 down to 480p60.

Capturing the display's Dolby Vision data block, reusing it behind an AVR, and the fields for building a custom DV block.

HTPC mode, OLED settings, TX +5V force, DHCP, static IP and port settings, hot-plug, reboot, config export and both reset options.

Flashing new firmware from a browser: choosing the file, sending it, the roughly 15-second restart, and what to try if it fails.

What ends up in the DR8K-CONFIG text file: unit and network details, EDID mode and flags, OLED settings and the raw RX and TX EDID data.

Driving the unit from a control system: port 2201, lowercase commands, line endings, and the set and get command patterns.

Answers on 4:4:4 at 4K60, PC and TV resolutions, HDMI versions, latency, long cables, lossless audio and powering the unit from USB.

Why an Apple TV 4K asks to retest Dolby Vision after an EDID change, and the settings that decide whether Atmos shows up.

LLDV maximum luminance, DCI-P3 versus BT.2020 primaries and the red-tint problem, and setting a player to output LLDV.

Two Shield-specific Atmos problems from the manual: Netflix stuck at 5.1 and Prime Video without Atmos.

Bandwidth, maximum video modes, audio formats, OLED, power, size, weight, input lag and certifications, as published in the manual.

Four field notes: command termination for iRule, sources that need a power-cord reset, cables for 192kHz ARC audio, and 4:2:2 at 12-bit.
