This Wiki page contains information for the “LCD-T50-800×480-HDMI” from Modtronix. It is a 5“ LCD Display with touchscreen for the Raspberry Pi.
This display(and most other similar 5” 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(for the LCD)! Only a small modification to the “Config.txt” file is required. See the “Configuring Standard NOOBS OS” section below for details. Additional drivers might however be required for the touch screen functionality to work!
Connection is very simply:
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:
On your Raspberry Pi, start the Terminal
Change directory to ”/boot“
Make a copy of your original “Config.txt” file. Lets call the copy “Config_bak.txt”:
sudo cp Config.txt Config_bak.txt
Open the “Config.txt” file(we will use the nano editor):
sudo nano Config.txt
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
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.
Reboot your Raspberry Pi:
On reboot, the whole LCD display should be used, and the touch screen should work.
For the touch screen to work with the Raspbian OS (NOOBS OS), some drivers have to be installed. Please Google how to do this. See “Additional Resources” section below for links to sites with information how to install this driver.
