Apart from pairing the DJI Goggles with a Mavic Pro drone and remote controller, there are two other connection combinations:
1. One Mavic Pro drone + two DJI Goggles + two Mavic Pro remote controllers
2. One Mavic Pro drone + one DJI Goggles + two Mavic Pro remote controllers

In Coach Mode, only the master remote controller can change the flight mode. The drone starts to respond to the slave remote controller only when the master remote controller doesn't give any commands for more than two seconds. The master remote controller can override anytime. In Dual Operation Mode (one drone + two DJI Goggles + two remote controllers), the slave DJI Goggles will not support Head Tracking Mode. If the remote controller and DJI Goggles are being operated by the same user, a spotter who is able to give instructions and warnings is required to ensure safe flying.

Phantom 4, Phantom 4 Pro, Phantom 4 Advanced, and Inspire 2.

Any device that has an HDMI port.

The Micro SD Card slot on the DJI Goggles is used to download files from the aircraft to the goggle’s onboard SD card for backup and to view captured video files.(Only videos with a resolution of 1080P/60fps or lower can be viewed via the Goggles.)

No.

Because of OcuSync. The same video transmission system carried by the Mavic Pro has also been integrated into the DJI Goggles, making the wireless connection between these two devices possible.

In HD Mode, the resolution of video transmission footage reaches 1080p/30fps for near field, lowering to 720p/30fps for far field or when affected by interference. In Smooth Mode, the resolution will remain at 720p/60fps. The former is for a clearer and immersive FPV experience, and the latter is for smoother FPV footage.

The resolution of video transmission footage seen in the DJI Goggles changes along with the video recording resolution. Therefore:
1. When video is recorded at 4K, the highest video transmission resolution is 720p/30;
2. When video is recorded at 2.7K, video transmission resolution tops out at 1080p/30;
3. When video is recorded at 1080p or below, depending on whether the frame rate is higher than 30fps or lower than 30fps, the max video transmission resolution will be 720p/60fps or 1080p/30fps, respectively.

Typical “2K” screens inside other brands of goggles are split into two 1280x1440 sections, one for each eye at 720p. The DJI Goggles use dual 1080p screens, meaning that each screen has a maximum resolution of 1920*1080.

HD video downlink latency (near field and free of interference) can be as low as: 110 ms (Mavic Pro, 720p60, video format: 720p120) 150 ms (Phantom 4 series, 720p60, video format: 720p60/720p120) 140 ms (Inspire 2+X5S, 720p60, video format: 1080p120) 190 ms (Inspire 2+X4S, 720p60, video format: 1080p60).

There are three main ways to update firmware:
1. Directly connect your DJI Goggles to a PC.
2. Pair your remote controller, drone, and DJI Goggles before connecting the remote controller to a PC, and update all three devices together.
3. Pair your remote controller, drone, and DJI Goggles, then connect the remote controller with the DJI GO app (or GO 4.0) to update the three devices simultaneously within the app.

No. For specific functions according to the different devices the DJI Goggles are connected to, please refer to the user manual.

In Head Tracking Mode, a drone's yaw depends on the pilot's head movements. If the pilot doesn't stop where he began, the drone will keep rotating until the pilot turns his head back to the original position.

For ease of operation, when the Mavic Pro is connected to the DJI Goggles, the C1/C2 buttons are automatically set to the Fn/Back buttons, which function the same as on the DJI Goggles.
