For several years, most manufacturers have started implementing ports USB-C In all launched laptops, a port that ended the need to hit the orientation of the cable before connecting it to the equipment. The theory indicates that thanks to the USB-C port, we can transfer data, send the signal to an external monitor in addition to loading it, however, in practice, it is really not because of the manufacturers.
If you have a portable house that incorporates one or more USB-C ports, you surely want to use it, you have verified that not everyone fulfills these three functions. This is what happened to one of Microsoft's product managers, when five minutes before demonstrating a customer, connecting a 4K monitor to the laptop, he saw how the screen has not shown no image.
USB4 Allows you to load the device, share data, send the image to several devices and support Thunderbolt devices. However, the diagnostic data that Windows collect show how 27% of the equipment with USB 4 shows a limited functionality notification when a USB-C cable is connected, which means that a USB4 functionality has not been implemented in the manufacturer, providing an experience very far from what it really is.
The design of all USB-C ports is exactly the same, so your specifications cannot be known at first glance. The drawing which, if it is placed with it and which indicates its advantages, is not easy to understand, forcing the user to prove the port by port to find the one that really offers the advantages he needs to always have the table of equivalences by hand.
All USB-C ports of laptops will have the same advantages
To solve this problem, Microsoft has created the Windows hardware compatibility program (WHCP), a program with which the company founded by Bill Gates wants manufacturers to use the same specifications in all USB-C ports of the equipment according to the following table.
Whatever the data transfer speed they offer, all the USB-C ports of laptops must be to offer a support to load the equipment and, at least, allow the sending of the signal to a external monitor With USB3 and a minimum of 4 devices with USB4.
Those who implement USB3, whose data transfer speed varies between 5, 10 and 20 Gbps do not have the compulsory support for Sparkle In Thunderbolt 3But those who integrate USB4 with data transfer speeds of 40 and 80 Gbit / s.
This affects not only laptops. Accessories also need to respond to these specifications. This change will take a few years to reflect in all laptops sold on the market, as you must first set the available stock of all recently published equipment.
