FS7: More Confusion over HDMI 8-bit vs 10-bit

Which HDMI standard does the FS7's HDMI port support? For a while, it had been debated and settled that it supported 10-bit video at 4K. But now there's this information which contradicts those conclusions.

Ran across this article:

"HDMI 1.4HDMI 1.4 is used on pretty much all UHD television sets and is the closest thing to a consumer standard for 4K signals available right now. The main limitation of HDMI 1.4 is bandwidth, as HDMI 1.4 is only able to handle 8-bit color at 24p or 30p. This is suitable for most situations, but 8-bit color is limiting for proper color correction. Also, HDMI is notoriously finicky when being used with switchers, distribution amplifiers, or any other similar types of devices. For this reason there are no converter boxes that convert HDMI 1.4 to other signals. But there are a large amount of conversion boxes available to convert other 4K signals into HDMI 1.4.
These signals can be converted into HDMI 1.4:
  • Quad-Link HD-SDI with the Blackmagic MiniConverter SDI to HDMI 4K or the AJA Hi5-4K
  • Dual-Link 3G-SDI with the Blackmagic MiniConverter SDI to HDMI 4K or the AJA Hi5-4K
  • 6G-SDI with the Blackmagic MiniConverter SDI to HDMI 4K
HDMI 2.0
HDMI 2.0 is the forthcoming HDMI standard. It supports up to 18 Gb/s of bandwidth and allows for higher frame rates and bit depths than HDMI 1.4. HDMI 2.0 supports 12-bit color at up to a 60p. It is also backwards compatible with HDMI 1.4 cables. HDMI 2.0 UHD TV sets aren't on the market yet, but some current HDMI 1.4 UHD sets should receive a firmware update to support HDMI 2.0. Like HDMI 1.4, HDMI 2.0 will most likely be hard to use with switchers and other forms of signal distribution, but could be a good option for post equipment since it supports a higher bandwidth than even Quad-Link 3G-SDI.
There are no converter boxes that work with HDMI 2.0 yet, but since TV sets will be able to update from 1.4 to 2.0 via a firmware update you might see some current converter boxes being upgraded to HDMI 2.0 in the future.

Sony FS7 HDMI supports 2.0, so good for 12-bits up to 60P in 4K.

Now the remaining question is what recorders support at least 10-bit HDMI, 4K input?

That article is wrong.

HDMI 1.4a & 1.4b standards can accept 10-bit 4K/UHD if properly configured and utilized. The Odyssey7Q+ can record 10-bit 4:2:2 4K/UHD via HDMI. The bandwidth limitation of this standard allows true 4K up to 24p and UHD up to 30p, but all in 10-bit 4:2:2.
 
Most mid-price TV's now include the 2.0. The higher end TV's will actually have the 2.0a connections, that allow for the High Dynamic Range.
