7" LCD Display

This Wiki page contains information for the “LCD-T70-800×480-HDMI” from Modtronix. It is a 7“ LCD Display with touchscreen for the Raspberry Pi.

This display(and most other similar 7” displays) requires some configuration/drivers to be installed on the RPi for it to function properly.

When using with a Raspberry Pi with the standard Raspberry Pi NOOBS OS, no drivers are required! Both the Display and Touch Screen will work without installing any drivers! Only a small modification to the “Config.txt” file is required. See the “Configuring Standard NOOBS OS” section below for details.

Features

  • 7“ LCD display for the Raspberry Pi 2 and 3
  • Module dimension: 0mm x 0mm (0” x 0“)
  • Operating Temperature -40°C to + 85°C

Connection

Connection is very simply:

  • Connect the HDMI port on LCD to the HDMI port of the Raspberry Pi.
  • Connect the micro USB port next the the HDMI port to any USB port on the Raspberry Pi.

Configuring Standard NOOBS OS

When you connect this LCD to a Raspberry Pi with the standard Raspberry Pi NOOBS OS, you will notice only the left side of the LCD display is used. The right side is unused and black. To fix this, the “Config.txt” file located in the ”/boot“ folder of the SD card has to be modified. Do the following:

Step 1:

On your Raspberry Pi, start the Terminal

Step 2:

Change directory to ”/boot“

cd /boot

Step 3:

Make a copy of your original “Config.txt” file. Lets call the copy “Config_bak.txt”:

sudo cp Config.txt Config_bak.txt

Step 4:

Open the “Config.txt” file(we will use the nano editor):

sudo nano Config.txt

Step 5:

Now find the line that starts with:

# uncomment to force a specific HDMI mode

Ensure the following lines are present below it(uncomment and/or add lines as required)

# uncomment to force a specific HDMI mode
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt=800 480 60 6 0 0 0

Step 6:

Save the file by pressing “Control” and “X” key. A windows will ask if you want to save modified file. Press 'Y' key, followed by “enter” to save file.

Step 7:

Reboot your Raspberry Pi:

sudo reboot

On reboot, the whole LCD display should be used, and the touch screen should work.
