To connect your PC to the external monitor , please make sure that you have used the correct type of cable, and all accessories properly connected. The following are common connectors you will use:
HDMI connector
HDMI (High-Definition Multimedia Interface) is a digital connection type for transferring the uncompressed audio/video signal and is HDCP compliant for DVD, Blu-ray, and other protected content playbacks.
USB Type-C connector
Please type your details
USB Type-C (USB-C) has multiple functions, but it’s not all USB Type-C connectors have a display-supported feature. For more details, please refer to How to determine the function of USB Type-C to learn more about your PC whether it has a display output function or not.
DisplayPort connector
DisplayPort (DP) is a digital interface used to connect a video source, such as a computer, to a display device like a monitor. Developed by the Video Electronics Standards Association (VESA), it can also carry digital audio, USB, and other types of data over a single cable.
Mini DisplayPort connector
Mini DisplayPort is a smaller size of DisplayPort, and it is commonly utilized on laptops.
DVI connector
Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source, such as a video display controller, to a display device, such as a computer monitor. It was developed with the intention of creating an industry standard for the transfer of uncompressed digital video content.
The DVI connector on a device is given one of three names, depending on which signals it implements:
- DVI-I (integrated, combines digital and analog in the same connector; digital may be single or dual link)
- DVI-D (digital only, single link or dual link)
- DVI-A (analog only)
VGA Connector
The Video Graphics Array (VGA) connector is a standard connector used for computer video output. Originating with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector went on to become ubiquitous on PCs, as well as many monitors, projectors and HD television sets.
