HDMI 4 Pi: 5" Display no Touchscreen 800x480 HDMI/VGA/NTSC/PAL
This is the HDMI 4 Pi: 5" Display no Touchscreen 800x480, a cute little TFT display with WVGA 800x480 resolution. We tried to get the smallest display that would be good for embedded computing usage and at a good price. The visible display measures 5" diagonal and is a 'raw' TTL display as is used in portable electronics. We include a driver board with HDMI, VGA and Composite inputs. The display is very easy to use - simply connect a 5-12V DC adapter to the 2.1mm center-positive DC jack, then connect a digital video source to one of the ports. Voila, a display!
It is not an IPS display so its best for direct viewing, our 7" and 10" HDMI IPS displays are designed for any angle view.
There's a little wired PCB with little buttons that let you enter a menu system for adjusting brightness, color and contrast. It tries to auto-detect which input you have and switches to that one or you can 'select' from the menu keypad which to display.
To demonstrate it, we took some photos with the display connected to a Raspberry Pi, but it will also work connected to any device with HDMI, VGA or NTSC/PAL output. It will not work with a device that only outputs DVI (without a DVI->HDMI converter) or SECAM.
For use with a Raspberry Pi we suggest editing config.txt to set the HDMI to 800x480 in case it doesn't detect the resolution properly. You can see the suggested config.txt below. The easiest way to edit the config.txt is to put the Pi SD card into an every day computer and edit config.txt with any text editor and save. For use with a BeagleBone black, we found it works when plugged in, no configuration required.
We show the TFT above on a wire stand, which is not included. If you want to extend the FPC cable between the driver and the TFT, you can grab a 10" long cable and swap it for the 4" one included.
A power adapter is not included! Any 5 to 12VDC adapter will work nicely: we prefer 9V DC.

Here is our suggested config.txt
# uncomment if you get no picture on HDMI for a default "safe" mode #hdmi_safe=1 # uncomment this if your display has a black border of unused pixels visible # and your display can output without overscan #disable_overscan=1 # uncomment the following to adjust overscan. Use positive numbers if console # goes off screen, and negative if there is too much border #overscan_left=16 #overscan_right=16 #overscan_top=16 #overscan_bottom=16 # uncomment to force a console size. By default it will be display's size minus # overscan. #framebuffer_width=1280 #framebuffer_height=720 # uncomment if hdmi display is not detected and composite is being output hdmi_force_hotplug=1 # uncomment to force a specific HDMI mode (here we are forcing 800x480!) hdmi_group=2 hdmi_mode=1 hdmi_mode=87 hdmi_cvt 800 480 60 6 0 0 0 # uncomment to force a HDMI mode rather than DVI. This can make audio work in # DMT (computer monitor) modes #hdmi_drive=2 # uncomment to increase signal to HDMI, if you have interference, blanking, or # no display #config_hdmi_boost=4 # uncomment for composite PAL #sdtv_mode=2 #uncomment to overclock the arm. 700 MHz is the default. #arm_freq=800 # for more options see http://elinux.org/RPi_config.txt
