Betaflight OSD allows the pilot to view in-flight information and telemetry data overlaid onto their FPV camera feed. This is where you can configure the OSD elements and their layout, as well as the alarms and warnings which will be displayed.
OSD requires a supported device. Supported devices include the onboard MAX7456 featured in many flight controllers, the FrSky OSD board and digital VTXs which support the MSP Displayport protocol.
OSD elements enabled by toggling the checkbox next to the element. Elements can then be moved by dragging them around the Preview pane, changes are reflected in real-time and viewable via the VTX and goggles. Three profiles are available and can be swapped to provide different elements and layouts.
Active OSD profiles
Selects the OSD profile which will be overlaid on the camera data.
Auto - attempts to guess the appropriate output type
PAL - Uses a 30 columns x 16 row grid of OSD elements. If the MAX7456 chip is used then this must match the camera signal
NTSC - Uses a 30 columns x 13 row grid of OSD elements. If the MAX7456 chip is used then this must match the camera signal
HD - Used by Digital VTXs which accept OSD commands via MSP Displayport
HD OSD defaults to a 53 column x 20 row grid of OSD elements. When the VTX is online BetaFlight will query via MSP Displayport to determine the optimum grid size and may update the grid to match what is supported by the digital VTX system

When using a MAX7456 chip the font glyphs are uploaded from the Font Manager
This can be used to select different font styles which heavier or lighter lettering and different styles. Use Upload Font to save changes
A custom boot logo can be uploaded. The image must be 288x72 pixels, and green/white/black. Green areas are rendered as transparent. Use Upload Font to save changes
Font upload max be required when upgrading from older versions of Betaflight as font symbols have been added and changed over time. In particular if your crosshair looks wrong or if your display appears garbled or using incorrect characters you should try uploading the font again.
