για να έχει απόδοση πρέπει πρώτα να την εγκαταστήσεις στο μηχάνημα. Αν τις πουλάς κατά την διαδρομή, απόδοση δεν βλέπεις. :p

When HDMI 2.1 Isn't HDMI 2.1 - The Confusing World of the Standard, "Fake HDMI 2.1" and Likely Future Abuse

The capabilities and features are things not previously possible with older HDMI standards like v2.0, or at least not in the more mainstream way they are supported now with v2.1. They include:

  1. Support for much higher bandwidths than older generations, allowing for…
  2. Support for higher resolutions – including 4K and even up to 8K
  3. Support for the combination of 4K and 120Hz high refresh rate (including at 10-bit, HDR and without colour compression)
  4. Variable Refresh Rate (VRR) support
  5. ALLM (Auto Low Latency Mode) support

The display that prompted this investigation was from Chinese manufacturer mi.com, and was their so-called “Xiaomi Fast LCD Monitor 24.5-inch 240Hz version“. This is a 24.5” sized display with a 1080p resolution and 240Hz refresh rate. At the bottom of their product page they list inclusion of 2x HDMI 2.1 ports.

However, beneath that at the bottom of the page hidden in the terms and conditions they then say the following (translated): “Due to the subdivision of HDMI certification standards, HDMI 2.1 is divided into TMDS (the bandwidth is equivalent to the original HDMI 2.0 and FRL protocols). The HDMI 2.1 interface of this product supports the TMDS protocol, the maximum supported resolution is 1920×1080, and the maximum refresh rate is 240Hz.”

This rang alarm bells for us, as it appeared that they were advertising a device which had only the capabilities of HDMI 2.0 under the new HDMI 2.1 name. It even specifically says it only used TMDS from v2.0 and not FRL. We’ve already touched on what we think an average consumer will expect when they see HDMI 2.1 listed, and so we queried this with HDMI.org, the HDMI Licensing Administrator to see whether this was dodgy or “fake”.

 

We contacted HDMI.org who are the “HDMI Licensing Administrator” to ask some questions about this new standard, seek clarification on several questions we had and discuss the Xiaomi display we mentioned above. Here is what we were told:

  1. HDMI 2.0 no longer exists, and devices should not claim compliance to v2.0 as it is not referenced any more
  2. The features of HDMI 2.0 are now a sub-set of 2.1
  3. All the new capabilities and features associated with HDMI 2.1 are optional (this includes FRL, the higher bandwidths, VRR, ALLM and everything else)
  4. If a device claims compliance to 2.1 then they need to also state which features the device supports so there is “no confusion” (hmmmm)

So according to what they have told us, this means that in theory all devices with an HDMI 2.x connection should now be labelled as HDMI 2.1, even though at the end of the day they may only offer the capabilities of the older HDMI 2.0 generation. With HDMI 2.0 certification now discontinued, these are basically 2.0 devices hiding under the replacement banner name of 2.1. They don’t have to offer any new capabilities whatsoever, but they are still supposed to be labelled as 2.1 it seems.

 

This means that actually what Xiaomi are advertising with their 24.5″ 1080p 240Hz monitor is correct, by the definition of the HDMI licencing administrator. It’s not “fake HDMI 2.1” after all. The ports have absolutely no new capabilities beyond 2.0, yet they are being advertised to consumers as 2.1 which in my opinion is misleading. Since it has none of the new capabilities there is nothing for them to list alongside that HDMI 2.1 name, so it’s just blank. Obviously you can tell that the screen will be a max 1080p and 240Hz (120Hz for consoles) so you wouldn’t be expecting 4K 120Hz here anyway, but the use of that name might well imply to an average consumer that it would feature things like HDMI-VRR or ALLM.

This would of course get even more confusing and misleading if a screen with a 4K resolution and 120Hz+ refresh rate did this. If it only had HDMI 2.0-type ports and bandwidth then that could still support 4K 120Hz, but it would have to be at 8-bit colour depth and with 4:2:0 chroma sub-sampling to fit within the older TMDS bandwidth. This is what we saw on the Asus ROG Swift PG32UQX, but at least Asus were up front and labelled it as HDMI 2.0 and called out the limitations. What if they hadn’t though? What if they’d just listed 4K 120Hz over HDMI and called it HDMI 2.1 (as HDMI org say you can)? You’d probably expect full colour support in that case. They’d be listing what is supported but aren’t calling out what isn’t supported as they don’t have to apparently. And what about features like VRR and ALLM? If the ports were labelled as HDMI 2.1 you’d probably expect these to be featured, but you would only know for sure if the manufacturer listed them specifically, and the absence of them in the spec would actually mean they aren’t supported.
