I think you are mistaken.

If you send it 255, it scales it to 235, so of course you can see "WTW" since it isn't actually WTW, it's just white.

There's no way to send raw 0-255 numbers to the display using ChromeCast - it always translates 0-255 into 16-235, so there is no way to test WTW or BTB using it.

Yes, the i1d3 has it's spectral sensitivities programmed into it. The driver deals with combining those with the .edr/.ccss files automatically, to manufacture a 3x3 calibration matrix on-the-fly.

Slower, won't synchronize to refresh displays.

Yes. Won't work with commercial video calibration software though.

No, ArgyllCMS/HCFR doesn't currently use AIO mode, because it doesn't need to. I implemented good synchronized measurements using the modes that are available in both the Rev A and Rev B.

HCFR/ArgyllCMS/X-Rite uses the Windows HID driver by default to talk to the i1d3. If there is some other system driver capturing the i1d3, it needs to be removed.

Sounds like a hardware fault with the i1d3. If it's the cable, you might be able to fix it. If the electronics has lost its mind, you will need a replacement.

Definitely not. "Display Calibrations" = Meter calibrations for different display types. i.e. .edr/.ccss files.

If you are using a not-ancient version of HCFR, you are using the ArgyllCMS drivers. But in any case, running "dispwin" doesn't involve any of that, since there is no need to access an instrument to...

Right - that fits with the V1.8.3 code limiting mDNS to one hop. So ArgyllCMS V1.9.1 may well fix that.
When someone gets around to doing the "work" needed to test it, we'll know for sure.

It's hard to connect to Chromecasts because they rely on mDNS, and operating system support for mDNS is all over the place. So in the ArgyllCMS driver I've tried to bypass all that and do my own mDNS...

Unfortunately it is still on the "to do" list. There are some preparations to support it,
but I simply ran out of time for it and the Prisma. The spectraval is supported though.
