The display config options are: Screen On Duration, Auto Carousel Interval, Always Point North and GPS Format. Display config uses an admin message sending a `Config.Display` protobuf.

## Device Config Values

### Screen On Duration

How long the screen remains on after the user button is pressed or messages are received.

### Auto Carousel Interval

Automatically toggles to the next page on the screen like a carousel, based the specified interval.

### Always Point North

If this is set, the compass heading on the screen outside of the circle will always point north. This feature is off by default and the top of display represents your heading direction, the North indicator will move around the circle.

### GPS Format

The format used to display GPS coordinates on the device screen.

Acceptable values:

| Value  |           Description           |
| :----: | :-----------------------------: |
| `DEC`  |         Decimal Degrees         |
| `DMS`  |     Degrees Minutes Seconds     |
| `UTM`  |  Universal Transverse Mercator  |
| `MGRS` | Military Grid Reference System  |
| `OLC`  | Open Location Code (Plus Codes) |
| `OSGR` | Ordnance Survey Grid Reference  |

### Prefered display units

switch between `METRIC` (default) and `IMPERIAL` units

### Flip Screen

If enabled, the screen will be rotated 180 degrees, for cases that mount the screen upside down

### OLED Defintion

The type of OLED Controller is auto-detected by default, but can be defined with this setting if the auto-detection fails. For the SH1107, we assume a square display with 128x128 Pixels like the GME128128-1.

Acceptable values:

|     Value      |                 Description                 |
| :------------: | :-----------------------------------------: |
|  `OLED_AUTO`   |       Auto detect display controller        |
| `OLED_SSD1306` |          Always use SSD1306 driver          |
| `OLED_SH1106`  |          Always use SH1106 driver           |
| `OLED_SH1107`  | Always use SH1107 driver (Geometry 128x128) |

### Display Mode

The display mode can be set to `NORMAL` (default), `TWOCOLOR` or `INVERTED`. The `TWOCOLOR` mode is intended for OLED displays with the first line of output being a different color than the rest of the display. The `INVERTED` mode will invert that bicolor area, resulting in a white background headline on monochrome displays.

### Heading Bold

The heading can be hard to read when 'INVERTED' or 'TWOCOLOR' display mode is used. This setting will make the heading bold, so it is easier to read.

:::tip

Because the device will reboot after each command is sent via CLI, it is recommended when setting multiple values in a config section that commands be chained together as one.

```shell title="Example:"
meshtastic --set display.screen_on_secs 120 --set display.gps_format UTM
```

:::

```shell title="Set Screen On Duration (Default of 0 is 10 minutes)"
meshtastic --set display.screen_on_secs 0
meshtastic --set display.screen_on_secs 120
```

```shell title="Set Auto Carousel Interval (Default of 0 is Off)"
meshtastic --set display.auto_screen_carousel_secs 0
// Set to 2 Minutes (120 Seconds)
meshtastic --set display.auto_screen_carousel_secs 120
```

```shell title="Specify GPS format on device screen"
meshtastic --set display.gps_format UTM
```
