DisplayPort connector A DisplayPort port (top right) on a laptop from 2010, near an Ethernet port (center) and a USB port (bottom right). DisplayPort (DP) is a proprietary [a] digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA).
One difference with the M91p is that the M92p comes with four USB 3.0 ports on the rear of the computer, whilst the M91p only offers USB 2.0 ports. [ 31 ] In a review for ZDNet , Charles McLellan wrote, "Unless internal expansion is required, we can find little wrong with Lenovo's ThinkCentre M92p as a business-class small-form-factor PC (and ...
According to a USB-IF chairman, "at least 10 to 15 percent of the stated peak 60 MB/s (480 Mbit/s) of Hi-speed USB goes to overhead—the communication protocol between the card and the peripheral. Overhead is a component of all connectivity standards". [1] Tables illustrating the transfer limits are shown in Chapter 5 of the USB spec.
However, the UHBR10 DP speed matches USB4 Gen 2 in bit rate and encoding, whereas the UHBR20 DP speed matches USB4 Gen 3 in bit rate and encoding. A USB and DP certification service lists USB Gen 1 cables ("5 Gbps") as supporting UHBR10 speeds, which would fit for having the same requirements as USB4 "20 Gbps" connections. [51]

The throughput of each USB port is determined by the slower speed of either the USB port or the USB device connected to the port. High-speed USB 2.0 hubs contain devices called transaction translators that convert between high-speed USB 2.0 buses and full and low speed buses. There may be one translator per hub or per port.
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
