How to Connect Two Laptops Together With HDMI
Most laptops built within the last five years feature HDMI ports, which resemble longer and thinner versions of USB ports used to connect flash drives and printers. All you require for use is an inexpensive HDMI cable; both your laptop and monitor must also feature appropriate inputs for HDMI connections.
There are also newer standards like USB-C, Thunderbolt, and DisplayPort; these ports carry power and data but may not support HDMI or similar video interfaces.

Doing it right takes adapters and cables of the right sort – which fortunately are easily available at an inexpensive cost. Your HDMI cable must support audio/video data transfer as well as full HD resolution (1,920×1,080 pixels); other monitors may support higher resolutions – be sure to check their specifications to make sure that its HDMI port can accommodate them!
If your older monitor uses analog connection standards like DVI or VGA, an HDMI-to-DVI or HDMI-to-VGA adapter may allow you to connect it to a laptop that only features HDMI ports; however, be aware that these older connections won’t provide optimal performance.
The HDMI connector looks similar to a regular USB plug, but features a trapezium shape instead of prongs. It includes both male and female connections; those on computers or laptops typically utilize male ends while most devices utilize female connectors.
Though it is technically possible to connect two laptops via HDMI cable, doing so is not advised as it could potentially short circuit or burn out one or both HDMI ports of either device. Unfortunately, most laptops only feature output HDMI ports and cannot send or receive data through input HDMI ports.
HDMI ports on laptops may not be designed for high-speed data transfer, causing possible lag or other issues with the connection. Therefore, a Thunderbolt or DisplayPort connection could provide better results.
There are various adapters that can be used to connect laptops via HDMI. These adapters can be found at most electronics stores or online and feature two HDMI ports on each end and an USB connector plugged into both ends for use with computers or laptops. Furthermore, some adapters also serve as converters from DVI or VGA connections to HDMI connectivity.
A common way of using an HDMI cable between two laptops is connecting them both to a television or monitor via an HDMI cable, enabling both laptops to share a screen for work or school purposes. There are some stipulations you should be mindful of before attempting this method: firstly, both laptops must be within range of each other as signal may not reach both computers; additionally, both must possess HDMI inputs as otherwise this cable cannot only be used as outputs.
An alternative solution would be using an adapter that converts HDMI into DVI or VGA connections; these adapters can usually be found at most electronics stores for relatively cheap. Finally, using a USB-C or Thunderbolt-to-DisplayPort adapter may also work; such an adapter allows converting laptop’s USB-C or Thunderbolt ports into HDMI – though you would require an expensive cable connection between these adapters and an HDMI monitor for this option.
Assuming both laptops and monitors have compatible inputs and outputs, setting up an extra monitor should be straightforward. Once Windows recognizes it, users can make any additional settings such as arrangement and resolution adjustments they desire for their new monitor.
A laptop docking station is an accessory designed to expand your laptop’s connections. Typically it connects via USB-C port and provides additional ports for various types of devices as well as power for your device. Some hubs even include Ethernet or HDMI ports which may otherwise be hard or impossible to find on your own computer.
Some hubs are small and portable, making them convenient when traveling or needing to connect multiple laptops at the same time. For instance, this USB-C hub with HDMI, compatible with both Windows and macOS OSes, supports different video connections while connecting to HDMI monitors or TV sets with various resolution support.
Other laptops may require more powerful hardware or specific ports in order to function optimally, like newer MacBook models with fewer ports compared to their predecessors; a good USB hub may help restore some of this flexibility that was taken away by manufacturers.
This no-frills hub, compatible with both USB-C and USB-A devices, adds four extra ports to your laptop computer. It is lightweight and comes equipped with individual on/off switches for each port – as well as having a two-foot cable so as not to require long extension cords.
Not all hubs simply add more ports – some hubs also provide features that make them useful in particular situations, like acting as HDMI-to-USB converters if needed for connecting an external display to your laptop, or providing file transfers between various devices via USB connections.
Hubs can convert HDMI signals into VGA, composite and S-video; however it’s important to remember they cannot transmit both inbound and outbound frames at the same time, potentially leading to data loss or other problems depending on your signal type. While hubs may be cheaper alternatives to dedicated cables they do not work as effectively with networks such as Ethernet.
If you’re connecting two laptops together with an HDMI cable, using the appropriate cables is crucial to success. There are various cable types to select from; some perform better than others depending on your type of device you’re connecting to, resolution/frame rate requirements and how far away from each end you wish to run the cable. Single link DVI or DVI-I cables have up to 3.96 Gbit/s capacity which supports resolutions up to 1,920x 1,200 resolution. Conversely, dual link cables physically have more pins on their connectors which support higher data rates up to 7.92 Gbit/s for higher data rates that reach resolution of 1,920x 1,200 resolution.
Some cables offer extra features, like HDMI Audio Return Channel (ARC), which transmits high-quality audio along with video signals for improved picture quality and lower power consumption on devices. You may also consider optical cables that transmit data using light rather than magnetic fields – this can reduce interference and improve image quality as well.
While HDMI remains the go-to cable in home AV setups, there are other alternatives. Some newer laptops feature DisplayPort ports which connect directly with monitors using this type of connection type. You can find an assortment of DisplayPort cables online; many offer gaming and streaming features.
Consider getting a USB-C to HDMI adapter for your laptop – they can often be found for an affordable price on Amazon and are particularly helpful for older machines that lack HDMI ports. On Macs, there is also an adapter available that plugs directly into Thunderbolt 3 or USB-C ports and converts signals directly to HDMI output.
Once you have the appropriate cable, connecting two laptops and setting up a mirroring display should be relatively straightforward. Simply enable this in the screen settings on each machine – on Windows this would be located under Displays while Mac users would access this setting via System Preferences > Displays.
Keep in mind that this only works if both laptops are running the same operating system. If using different versions of Windows or combining macOS with Windows machines, your screen may temporarily go black but eventually come back online.
