We currently are looking for drivers for the Gateway FHD2400, Gateway support has a bunch of error when looking for the driver on their support site which is the case for many of their older devices. The User Manual (Below) doesn't mention anything about a driver install. There are many inputs on this device, make sure you have selected the correct one using the buttons on the monitor.
