Recently, Tony accidentally brushed a piece of news, which is quite speechless.
The news is roughly about an agency that pointed out that a 24.5-inch 240Hz gaming monitor released by a manufacturer a while ago may be suspected of being false, because its two HDMI 2.1 interfaces cannot achieve its due effect.
Although the vendor has marked a * note in the upper right corner of the leaflet, it is actually equivalent to the original HDMI 2.0 interface:
Due to the breakdown of HDMI certification standards, HDMl 2.1 is divided into two protocols, TMDS (bandwidth equivalent to the original HDMI 2.0) and FRL, the HDMl 2.1 interface of this product supports the TMDS protocol, the maximum resolution supported is 1920×1080, and the maximum refresh rate is 240Hz.
However, the agency still questioned whether this was appropriate, so it confirmed to the organization responsible for HDMI licensing, and the feedback was that the HDMI 2.0 standard no longer exists, and there is nothing wrong with calling it 2.1:
Good guys, dare to buy a monitor later can not only see whether its interface is HDMI 2.1, but also depends on what functions its interface specifically supports, otherwise it will be misled by publicity if you are not careful...
You should know that according to the original standard, the gap between HDMI 2.0 and HDMI2.1 is not generally large.
The former can be said to be an interface standard that is about to be replaced or eliminated, while the series of new features supported by the latter are enough to make the electronic equipment equipped with this interface war in the future, and it is also the kind that will never become obsolete in the next five years:
HDMI 2.1 supports variable refresh rate, HDMI 2.0 does not;
HDMI 2.1 supports dynamic HDR and static HDR, HDMI 2.0 only supports static HDR;
HDMI 2.1 supports 8K@60Hz and 4K@120Hz screen transmission, HDMI 2.0 supports up to 4K@60Hz;
In addition, the HDMI 2.1 interface also supports fast media switching and automatic low latency mode.
Other products aside, on the next-generation console PlayStation 5 and Xbox Series X released by Sony and Microsoft, the HDMI 2.1 interface exists as one of their biggest selling points.
Without this interface, their ultra-clear image quality and top-notch special effects would not be able to be presented on the monitor.
The practice of HDMI licensing organizations collectively referring to the original HDMI 2.0 and 2.1 interfaces as HDMI 2.1 is equivalent to making the HDMI 2.1 markings on electronic devices lose their distinguishing role, which is very outrageous.
It's not the first time something like this has happened.
Take the most popular USB interface now, in the USB 3.2 standard did not come out that will, the USB Standardization Organization originally stipulated that the tube USB 3.0 is called USB 3.1 Gen1, and the tube USB 3.1 is called USB 3.1 Gen2.
Then as soon as USB 3.2 came out, the name changed.
The new specification requires USB 3.1 Gen1 to be renamed USB 3.2 Gen1, USB 3.1 Gen2 to USB 3.2 Gen2, and the latest USB 3.2 interface to be directly called USB 3.2 Gen2x2.
欸, is to change the play, on the surface it looks like the upgrade is actually not rising, you can remember and distinguish them even if you are strong ~ ~
Previously, the WiFi Alliance named each generation of WiFi technical standards even more excessively.
802.11b、802.11a、802.11g、802.11n、802.11ac，802.11ax 。。。 These namings do not even have laws, and ordinary people simply cannot distinguish them from the naming of who is new and who is old.
Fortunately, since the beginning of the previous year, the WiFi Alliance has finally introduced a new numerical naming mechanism to WiFi, simplifying each generation of standards through "WiFi + digital", which makes us not confused:
It stands to reason that the significance of naming these standards is to make it easier for consumers to understand which generation the technology used in the product belongs to, so that we can make decisions among similar products.
If the naming of the standard is confusing or non-standardized, it is bound to leave a lot of room for manufacturers to operate.
It's honest to advertise a monitor with only an HDMI 2.0 interface under the new HDMI 2.1 name, and then to mark it with a * in the upper right corner and a note at the end.
You have not seen the manufacturer drill the standard naming loophole to make a naming of their own play, let people mistakenly think that it is an upgraded version or something better.
For example, because the industry does not clearly define the resolution range of mobile phone 3K screens.
So although the short side of the Find X2 has 1440 pixels like other 2K phones, because the long side of the Find X2 has increased to 3168 pixels, it is called a 3K screen:
For example, because the mobile phone industry at that time did not clearly point out what kind of screen fingerprint was the first few generations as the processor chip.
So you will see that once a manufacturer launches a new under-screen fingerprint phone, then the under-screen fingerprint technology it uses must be the latest, although the release time of these mobile phones is actually not long after:
Names like WiFi 6 Enhanced edition and WiFi 6+ on the router are also new names given by manufacturers to their own products, and they are essentially just a few new things than the original WiFi 6 router.
For now, when we buy a product instead of looking at its leaflet, it is better to look at the parameter page to be reliable, at least its data can give you a clear target, but when some parameters are marked with a * sign, then we must pull to the end to read the comment, otherwise it will not be unprovoked *.
I hope that other standard-making alliances can not learn HDMI, after all, the naming of the standard was originally used to prevent manufacturers from playing tricks on us, and now it seems to be the other way around, and it is not so brushed to brush the sense of existence.
Thank you all for watching!
