USB C is a connection, not a standard. You can’t use a TB3 cable on a USB C device, even though it has a USB C connecter and vice versa. USB 2.0 480Mnps, USB 3.0 5Gbps, USB 3.1 is were it got confusing because 3.1 and 3.2 (10Gbpa) seem the same. Now USB 3.2 2×2 is bonkers, and confusing people but at least USB 4 and TB4 cables will work with either device.. USB 3.2 2×2 is capable of 20Gbps, put is the first version that doesn’t have to be backwards compatible with USB 4.

The answer is USB A, USB B, USB C, USB mini and USB micro. USB C is just a form factor. Like lightning cables. So are you saying that through there entire lifespan lightning cables didn’t get any faster or charge quicker? That the first lightning cable ever has the same capabilities as the latest version? Same situation, just way more cooks in the kitchen,.
Regardless laying 12 USB C cables in front of me, I could probably guess which are for charging and have terrible data transfer speeds compared to a well made cable. Also my TB4/USB4 cables show both the TB symbol and have a 4 on them so I clearly know what the capabilities are.
Now, with that said, the people making the rules are getting sloppy, heck, they released 3.2 2×2, which can do 20Gbps and is the first USB revision that doesn’t have to be backwards compatible with USB 4. You will only get 10Gbps, it requires a special port. They sell external drives with this port. Yet no laptop has this port that I am aware of.
HDMI 2.0 no longer exist according to the HDMI forum. All 2.1 requirements are now OPTIONAL. Xiaomi is already selling gaming monitors marked as 2.1 that don’t do a single thing in the 2.1 spec. They are just 2.0b ports. It’s up to the manufacturer to disclose what capabilities the HDMI port is capable of. On Xiaomi’s website, it was buried deep in the fine print. It’s.a buyer beware market. Sadly there are going to be a lot of frustrated returns over this, and there should be. I honestly don’t know how you can just say the old format doesn’t exist anymore yet the new format only had to do what the pre virus version does.
Parents buying their kids a new TV for their next gen console are just going to see 2.1 as available, it’s way cheaper then others displays so they buy it, then have to figure out why it doesn’t work like it should. If you ask the average sales person at Best Buy if an HDMI port is capable of FRL5 speeds they will just look at you like your crazy. FRL5 means it can do 40Gbps which is what is required for all next gen features.
What about 3.2 2×2? That one, I simply can’t understand. 20Gbps, they sell external SSD’s with this port. No laptop I am aware of has this port, you can but an add on card for a PC. It’s really buyer beware at this point. HDMI 2.0 no longer exists and everyone can sell ports that say 2.1, but don’t do any of the now OPTIONAL features like VRR, QFT, QMS, ECT.. The HDMI peeps just decided 2.0 doesn’t exist anymore.
My understanding was TB4 and USB 4 cables will work on either port unlike TB3 and 3.2. no more having to make sure you are using a specific cable. Nothing fun about looking for one of the few USB C TB3 cables and only finding USB C cables.
Regardless 240W, should be great getting the battery to 50 or 60 percent but it will slow down dramatically as getting in that last 20 percent is way harder then the first 20 to 50. I bout one of those cables with a led display as showing go the charge rate. After 90 percent, your getting 1 to 5W max. No battery can quick charge to a 100 percent at full speed unless you want your battery to last 5 months or potential fire hazard. That’s why they always claim 50 percent in say, 15 minutes because that’s true but it slows down after that.
Honestly, it would probably be better to buy a spare battery for your laptop at that point, if you can. Even on my Lenovo laptop it stays under 10W until you start pushing it, then you see it go up to 50 to 60W. I know these cables aren’t 100 percent accurate regarding output wattage but better then guessing.
Also, the dumbest USB standard was left out which is 3.2 2×2. Yes, it’s real, it can do 20Gpbs, not on any laptops I have seen, only add on cards for workstations. It’s also the first revision that doesn’t have to be backward compatible so if you bought an external drive with this port, and had.a USB4 port it would still only do 10Gbps. SanDisk sells a model, the reviews on Amazon crack me up because nobody understands why they are only getting 10Gbps.
The peeps who make up the HDMI specifications have said 2.0 no longer exists and manufacturers can sell them as 2.1 ports, even if they don’t support all supposed requirements Now it’s up to the consumer to read the fine print and what the port is capable of. Xiaomi has already been selling monitors that have zero 2.1 features as 2.1 but they are really 2.0b ports. No VRR, no QMS, QFT, no 40Gbps even though the spec was 48. With that said, nothing outside next gen consoles or 8K, which is pointless IMO, needs that bandwidth. Standards no longer apply, buyer beware and we all know how that will work out.
Specs no longer matter. Always double check the fine print twice.
There is a new development and unfortunately it is not good news. The HDMI organization has confirmed to TFTCentral that manufacturers can now claim HDMI 2.1 support even if not a single HDMI 2.1 feature is supported. That is because "HDMI 2.0 no longer exists".
Here is the HDMI Licensing Administrator’s answer to TFTCentral:
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"
In fact, Xiaomi already advertises HDMI 2.1 support for one of its new LCD monitors that supports no HDMI 2.1 features. In the past, it would have been labeled as a regular HDMI 2.0 monitor because it supports only HDMI 2.0 bandwidth (over TMDS). This case prompted TFTCentral to contact the HDMI organization
