Features

1. Upgraded OLED Display & Optics:

Next-gen optics and OLED panel deliver 1920×1080 resolution, 100FPS frame rate, and 52° diagonal FOV -- offering a highly immersive FPV experience, especially when paired with digital VRX systems.

2. Enhanced Visual Performance:

Supports 4:3/16:9 aspect ratios, with adjustable focus (-2~+6 diopters) and IPD (58-71mm) to fit diverse vision needs and face shapes.

3. Practical Matte Finish:

New matte coating resists fingerprints and reduces glare for clearer viewing in various environments.

4. Reliable Reception & Recording:

Equipped with a 5.8GHz 48CH V3.3 Steadyview Receiver and H.264 DVR (60fps) for stable signal capture and high-quality video recording.

5. Versatile Connectivity:

Accepts 2~6S LiPo input and HDMI IN (720P 100FPS) for flexible setup with different FPV systems.

6. 3-Axis Head Tracking:

Built-in 3-axis accelerometer and 3-axis gyroscope enable precise head movement control.

Important Note

A cooling fan is installed in the right-side bay to regulate temperature for the high-performance OLED panel. As a result, the SKY04X PRO does not support diversity mode.
