FPV monitors are portable LCD screens that you can use to view the video feed from your drone.  Many include a built-in battery and receiver and are an all in one portable unit.  The advantage of using an FPV monitor over FPV goggles is that it gives you the freedom to look up at your drone as it is flying.  Popular among filmmakers having a separate screen lets you see exactly what your onboard camera sees.  Most FPV monitors also include a Sunshade that helps prevent glare on the screen, so you can still clearly see the screen outdoors.  All of our FPV monitors we sell have special firmware to prevent the blue screen issue when the FPV signal gets low.
