With a BlueBuilt Cable converter, you can connect 2 devices that have different connectors with each other. A cable converter turns one signal into a different signal, and it doesn't need power. This allows you to connect your HDMI monitor to your laptop with a USB-C port. You can choose from different connectors. A cable converter is also useful if you're on the go a lot to give presentations or for meetings. Thanks to the compact size, you can easily put it in your bag. The BlueBuilt cable converters are made of extra sturdy nylon, so they last long. In addition, you'll get an extra long 5-year warranty.
