EDID

Video flags explained

Video flags let you edit one picture capability at a time in a copied EDID, such as the FRL rate or HDR mode, while the rest of the display's data stays as reported.

The short explanation

When a device copies a display's EDID and modifies it, the flags are what you modify. Each corresponds to one capability the source will read and act on.

Where you run into it

Most real problems are one flag wide. VRR that is never advertised. An HDR mode you want removed because the display handles it badly. An FRL rate you want capped because the cable is marginal. Flags let you change exactly that one thing and leave everything else as the display reported it.

It also makes testing methodical: change one flag, observe, change it back. That is a far better way to find a fault than swapping cables.

How the DR HDMI 8K handles it

The DR HDMI 8K's video flags are FRL rate (disable, or cap at FRL1 to FRL5), VRR (enable or disable), ALLM (enable or disable), HDR (remove, or set HDR10, HDR10/HLG, HDR10+ or HDR10+/HLG) and DV (remove, or set a preloaded or custom Dolby Vision mode). They apply in COPY TX SINK EDID and MODIFY mode.

About the DR HDMI 8K: a 1500MHz / 48Gbps HDMI 2.1 repeater that reads, stores and rewrites EDID between your source and the rest of the system, and shows the link state on its OLED and web page — so a failing chain becomes something you can test one step at a time. See what the unit does →
