The HDMI licensor plans to stop using the HDMI 2.0 designation. Older monitors, TVs and display devices with FullHD resolution without new functions are also to be advertised with HDMI 2.1. The confusion among end customers is likely to be huge.
The end of HDMI 2.0?
Various specifications are grouped together under the name HDMI 2.1. HDMI 2.1 in one device can mean something completely different than in another. For example, it is important to consider the transfer rate (18 to 48 Gbit/s) for 4K UHD content at 144 Hz, for example, or optional features such as Variable Refresh Rates (HDMI VRR) and Auto Low Latency Mode (ALLM).
Previously, displays were labeled with the HDMI 2.1 standard as soon as at least one of these features was offered. HDMI 2.1 is necessary, for example, to achieve 4K resolution at 120 Hz on current consoles like PS5 and Xbox Series X.
In China, however, a
gaming monitor from Xiaomi is now being advertised as having HDMI 2.1, even though it actually only handles HDMI 2.0 and offers none of the new features. A hint that it is actually only the old standard is only found in the footnotes.
