Back in the day when we had an ISF tech, I remember learning that DVD players outputted their signal via component video, and we had the 0 IRE vs 7.5 IRE settings to contend with.
That is no longer the issue with HDMI, correct? Is there a preferred default on a setting like this?
This can still be an issue on RGB sources.
On component video signals (over HDMI, which should be cable boxes, BD players, and dedicated media players), the default should always be to have black at 7.5 IRE.
But on RGB defaulting sources (like game systems, HTPCs, and BDs if you set them that way), the range may actually be either "Full" or "Limited/Broadcast"... and while this should automatically negotiate between modern HDMI components, some screens can't, and even when they can, it sometimes doesn't work reliably.
I'd say the default setting on that screen should be "Light"... but if you feed it full-range you'll get horrible crushing, which may not be immediately obvious to an untrained eye - it'll just seem like everything's way too dark. Similarly, if you set it to "Dark" and feed it limited-range, blacks will become a medium-dark grey, which should be more obvious.
