Today’s computers come equipped with a variety of ports; from old USB ports to new ports like USB Type C with support for Thunderbolt 3. Even if you know all the common ports on PCs, it’s not easy to detect the type of cable or adapter suitable for connecting different devices, such as displays, TVs and network devices to a specific port.
When you buy a laptop, a convertible device (such as a Surface book) or a desktop computer, you may be interested in the ports on it. Support for more ports means less trouble and no need for different converters. But getting to know the ports and exchanges that are suitable for connecting different devices is useful.
3.5 mm audio jack
Other names: Headphone jack
Description: Most of us know this port as a headphone jack. The 3.5mm audio jack is the most common audio port on all computers, tablets and mobile phones. Thanks to this port, you can connect most commonly used headphones or speakers to your device. Some older devices have 3.5 mm separate ports for connecting headphones and microphones, but most modern devices use a common 3.5 mm jack for headphones and microphones.
Related Converters: If your device does not have a 3.5 mm jack, you can use a USB headphone or a USB 3.0 converter to use a 3.5 mm jack. Another option is the use of headphones and wireless speakers. If you’re using an iPhone, you can use the Lightning converter to a 3.5mm audio jack or headphones with a lightning connector. People using devices with a USB Type-C port can use USB Type-C converters to 3.5 mm jacks or USB Type-C headphones.
Other names: Ethernet port 100/10, Gigabit Ethernet port, RJ-45 port
Description: You will find this port on commercial laptops and desktop computers. Ethernet port provides direct connection to a network using wire. While Wi-Fi technology continues to grow, web-based connectivity is a valuable option, especially in places like hotels that may have a weak Wi-Fi signal. In the specifications of devices, this port is usually referred to as the Ethernet port 100/10 or Gigabit Ethernet port. But apart from these phrases, on all laptops and desktop computers, the maximum speed of this port is limited to one gigabits per second.
Related Converters: If your device does not have an Ethernet port, you can buy an Ethernet-to-Ethernet converter for $ 15 to $ 30. The price differences of these converters are related to the type of USB port; USB Type-C to Ethernet converters are usually more expensive than USB Type-A converters to Ethernet. Communication dock also often has an Ethernet port.
Description: An HDMI port, called the High Definition Multimedia Interface, means the most common port for connecting TVs, as well as many external displays and projectors. Based on the type of device’s graphics card, HDMI ports can support a maximum resolution of 4K, but there is no way to connect two displays simultaneously to an HDMI port. It should be noted that the HDMI port can simultaneously transfer video and audio.
Most devices have an ordinary HDMI port, but some ultra slim devices use Mini-HDMI ports that are smaller than normal HDMI ports and finding the right converter for it is not easy.
Related Converters: If your device has an HDMI port and you want to connect a monitor with a DVI port, you will need an HDMI to DVI converter. The price of this converter is about $ 10. There are also converters for converting USB Type-C to HDMI; however, your USB Type-C port must also have an image transfer capability. To convert HDMI to DisplayPort, you need a separate power source. This converter is a little more expensive than other converters, and costs about $ 30. Note that DisplayPort cables do not operate on an HDMI without a power source.
DisplayPort and Mini DisplayPort ports
Description: DisplayPort is the most advanced standard display connection available today. This port provides the ability to send images to a display with a maximum resolution of 4K and a frequency of 60 Hz, or simultaneously uploading images to three full HD resolution displays (with the help of a hub or dock). Most laptops that come with this port are smaller than the mini DisplayPort. DisplayPort provides simultaneous audio and video playback.
Related Converters: Many displays and most TVs lack DisplayPort. In these cases, you can use the DisplayPort to HDMI converter, which costs around $ 10. If you want to connect more than one display with a mini DisplayPort port to a laptop, you’ll need to create a hub with multiple connection streams, also known as MST hubs. The hub needs a separate power supply and costs between $ 70 and $ 100. USB Type-C converters to DisplayPort and Micro DisplayPort to DisplayPort are priced at around $ 10 or more.
Other names: DVI, DVI-I and Dual-Link DVI
Description: Usually you will not find this port on laptops, but most monitors with a full HD resolution or less, as well as most desktop computers, are equipped with a port. Most commonly used low-end monitors in the market will only have VGA and DVI ports, while DVI will be your best choice. Fortunately, you can connect your computer to a monitor with a DVI port with a converter, HDMI port and DisplayPort.
DVI ports are standard in UXGA resolution U (1920 x 1200 pixels) with a refresh rate of 60Hz. But if you want to get a 2K or 4K resolution, you need a secondary connection called the Dual-Link DVI. Most USB dockers have at least one DVI out port.
Related Converters: The cost of HDMI cable to DVI is about $ 10. For the DisplayPort cable, the DVI should pay about $ 15. The price of the DVI output converter to the VGA is $ 5. But connecting the VGA output to the DVI input on the monitor is very costly and difficult. USB docking devices with dual DVI outputs cost at least $ 100.
MicroSD card reader

Standard Thunderbolt 3
Description: Thunderbolt 3 is the fastest communication standard available on the market. Thunderbolt 3 provides 40 gigabit per second data transmission, which is four times faster than the second-generation USB 3.1. This high-speed connection also supports simultaneous output to two 4K monitors, because each port equipped with Thunderbolt standard 3 transmits two DisplayPort signals simultaneously. On some new devices, it’s possible to connect external graphics cards through ports that are equipped with Standard T-Mobile 3. This makes it possible to run heavy games on ultra-thin laptops.
The Thunderbolt 3 standard uses USB Type-C ports. The ability to connect standard USB devices to USB Type-C ports equipped with the Thunderbolt 3 standard can also be used to charge the laptop and tablet.
Prior to the emergence of Thunderbolt 3 standard ports on laptops in late 2015, small devices supported Thunderbolt 2 and Thunderbolt’s first generation standard. With a convertible cable, there is also the possibility of connecting to the Thunderbolt 3 standard port to devices used by previous Thunderbolt generations.
Cable and Converters: The cost of the Thunderbolt 3 cable is less than $ 25; however, carefully read the specifications before purchasing, because some cables support a maximum speed of 40 Gbps instead of a maximum speed of 20 Gbps. Thunderbolt 3 docking stations allow you to connect a variety of monitors and accessories to a price of around $ 200. The use of USB Type-C cables and docking and other devices that support the USB Type-C standard also come with Thunderbolt 3 ports. The Thunderbolt 3 converters are somewhat expensive for previous generations of Thunderbolt and cost more than $ 100.
Description: This port should be considered as the source of all visual outputs. The VGA port’s history dates back to 1987, but is also used in some of today’s monitors and projectors. The 15-pin VGA port is fairly large, which is why it’s not on most laptops and desktop computers today. Signals are transmitted in analogue port, which means that the quality of the signal decreases with cable length increase. The maximum resolution supported by this port is 1920 x 1200, which makes it unlikely for today’s use.
Related Converters: It’s not possible to switch VGA out ports to other ports (DVI, DsiplayPort and HDMI), but with some inexpensive converters, you can connect to other VGA monitors. The price of DVI to VGA, HDMI to VGA and DisplayPort to VGA is less than $ 10.
