Differences Between Wired and Wireless Portable Monitors

By Marketing Lexuma 0 comments

In order to cater the needs of customers, many different versions of external monitors are launched in the market, for example, monitors in different resolutions, different colors and different connection methods. It is not difficult to see external monitors from one series provide both wired connection and wireless connection version.

What are the differences between wired and wireless portable monitors?

The most apparent difference must be the connection method. Let me firstly introduce some of the common connection methods of wired and wireless monitors respectively.

Common Wired Monitor Connection method



High-Definition Multimedia Interface (HDMI) ports can be mainly found in new computers and HD TVs. HDMI cables carry both HD video and audio signals. Therefore, if you connected your device to an external monitor which has built-in speakers, audio can also be exported and come out from the external monitor.

As many types of devices with different built-in ports are launched, there are also various types of HDMI cables in the market, like HDMI to Type C, HDMI to USB and HDMI to mini HDMI.


2. Type C


Type C, also known as USB-C, is a connector that is able to transmit data and power on a single cable. However, not all devices with Type C port support data transmission function.

Just like HDMI cable, there are also many types of Type C cables, for example, Type C to Type C, USB to Type C and Lightning.


3. VGA



VGA connector was developed by IBM and introduced in 1987. VGA utilizes analog signals, which means it's only capable of lower resolutions and a lower quality display on screens.

Because of its limitation, it is uncommon to see VGA in new devices. VGA is mainly replaced by other connectors like HDMI.

Common Wireless Monitor Connection method

1. WiFi


For most of the wifi wireless connection, a screen mirroring adaptor will usually be attached with the external monitor, in order to connect it with the wifi. The principle of it is transferring display data over wifi network.


What are the advantages and disadvantages of both types of connection?

Wired Monitors



More stable connection

  • Connection will not be disrupted by outside interference like signals from other devices

Damages to cable affects heavily

  • If the cable is broken, the connection will not work and a new cable is needed

Easy setup

  • The external monitor can be connected to the device by physical cables only

Low portability

  • If you want to carry the external monitor around, your own device is linked together and you need to carry both devices at the same time

Prompt response time

  • As the wire connection is not easy to be interrupted by outside factors, the response time of the external monitor will be nearly as fast as the original device

Human error affects

  • If they are unplugged or loosen by human error, the network expansion will be damaged

Wireless Monitors

  • No more restriction brought by the wire
  • walk around the room and display what you're doing as you interact with students

More complicated setup

  • Need few more steps after turning on the device

More portable and lighter in weight

  • No more any other accessories to be carry while taking it around

Unstable response time

  • Depends on wifi network stability

No limitation on devices model

  • The ports of external monitor may not match with the own device
  • Can be connected when there is wifi

  • The bluetooth earphone connection will be disrupted
