Since connecting two laptops with an HDMI cable doesn’t work, how else can you connect two laptops to stream video data? However, not all manufacturers include this protection circuitry to cut down manufacturing costs, especially in cheaper laptops. This can protect an output HDMI port from any charges from another output HDMI port. Luckily, manufacturers design the front of HDMI ports to have a chip of protection circuitry. So when you plug two output HDMI ports together, a charge is sent through the HDMI cable to each other. Usually, a charge of five volts is sent through the HDMI cable from the output HDMI port. This is because when an HDMI cable is plugged into an output HDMI port, the output HDMI port will begin to send video data through the cable.īut to send video data, you need to use electricity.
Three main scenarios could happen if you connect two laptops with an HDMI cable: nothing happens, one laptop short circuits, or both laptops short circuit. What will happen if I connect two laptops with an HDMI cable? This is why connecting two laptops with an HDMI cable doesn’t work. But since neither of them are input HDMI ports, they don’t receive the video data.īecause they are designed to only send video data, they won’t even be able to recognize the connection to another device that sends video data. So when you plug an HDMI cable into the output HDMI ports of two laptops, both laptops will try to send video data through the cable to the other laptop. Some laptops have input HDMI ports, but this is rare. Īn output HDMI port can’t receive video data-it can only send video data. To understand why you can’t do this, let’s go over how the HDMI ports in your laptops work.Īn HDMI port in a laptop is most often an output HDMI port, which means that it sends video data to a receiving device with an input HDMI port, like a TV, a PC monitor, or a projector. No, you can’t connect two laptops with an HDMI cable.
