Wefly Thunder JF-17 MFCD Setup Guide

## Electrical connections

1. Each MFCD needs to be connected with a power cord and an HDMI cable. It is recommended to use the video output port that comes with the graphics card. If there is no extra video output port on the computer graphics card, you can use the attached USB to HDMI adapter.
2. The MFCD with USB Type-C interface is the main device, and the main device is connected to the USB port of the computer with a USB Type-C data cable.
3. The MFCD without USB Type-C interface is a slave device. Use a 5P terminal cable to connect the slave device to the master device. The two connection ports can be selected arbitrarily.

## Display setting

Take the following layout as an example: No. 1 is the main monitor with a resolution of 3840×2160.

## Screen coordinate system

![](/media/202207/2022-07-05_170134_434214.png)

- The origin (0,0) of the screen coordinate system is in the upper left corner
- The coordinates increase to the right along the X axis and increase downward along the Y axis
Display No. 1: starting coordinates X=0, Y=0, width=3840, height=2160
Display No. 2: starting coordinates X=3840, Y=0, width=768, height=1024
Display No. 3: starting coordinates X=3840 + 768, Y=0, width=768, height=1024
Display No. 4: starting coordinates X=3840 + 768 + 768, Y=0, width=768, height=1024
- overall display area
The overall display area is the area used by DCS for display. The calculation method of the overall display area: width of the display area = 3840 + 768 × 3 = 6144, height = 2160

## Screen configuration file

The configuration file is in the following path: `C:\Users\[UserName]\SavedGames\DCS\Config\MonitorSetup`
Chinese system path: `(C:\Users\[username]\Saved Games\DCS\Config\MonitorSetup)`
Create a new configuration file and name it `3840_TripleMFCD.lua`, copy and paste the following code into the file, and save it.

```
_  = function(p) return p end
 name = _('3840_TripleMFCD')
 description = '3840_TripleMFCD'

JF17_LEFT_MFCD = { x = 3840, y = 0, width = 768, height = 1024 }
 JF17_CENTER_MFCD = { x = 3840 + 768, y = 0, width = 768, height = 1024 }
 JF17_RIGHT_MFCD = { x = 3840 +768 + 768, y = 0, width = 768, height = 1024 }

Viewports = {
  Center = {
   x = 0,
   y = 0,
   width = 3840,
   height = 2160,
   aspect = 3840/2160,
   dx = 0,
   dy = 0
  }
 }
 UIMainView = Viewports.Center
 GU_MAIN_VIEWPORT = Viewports.Center

```

## Resolution and display settings in DCS

Enter the DCS to open the settings, take the above display layout as an example, select the resolution as 6144×2160, and select the configuration file name written in the second step for the display setting.

## Button setting in DCS

Take the left MFCD of JF-17 as an example, D1 to D5 correspond to the 5 buttons from left to right at the bottom of the display screen in turn, double-click the option corresponding to D1 under the `Wefly JF-17 MFCD` label.

If the following interface is displayed, it means that the key setting is successful.

The rest of the button settings are analogous, L1 to L8 correspond to the 8 buttons on the left side of the display from top to bottom, R1 to R8 correspond to the 8 buttons on the right side of the display from top to bottom, U1 to U5 correspond to the top of the display  5 keys from left to right.
When setting the brightness, double-click the option corresponding to "Brightness +" under the `Wefly JF-17 MFCD` label, and then press the "+" button of the BRT button.

The button setting of contrast and symbol can be deduced by analogy, among which the CONT button stands for contrast, and the SYM button stands for symbol.
