HDMI 4 Pi: 7" Display & Audio 1280x800 IPS - HDMI/VGA/NTSC/PAL
Make a lovely audio/video setup with a 7" IPS screen with HDMI stereo speaker support. For video, we have a beautiful bright 7" TFT display with incredibly high resolution and great angle-visibility! We tried to get the thinnest, brightest, highest resolution display that would be good for embedded computing usage. The visible display measures 7" diagonal and is a 'raw LVDS' display as is used in a tablet which makes it ultra thin and very bright. We include a driver board with HDMI, VGA and Composite inputs as well as stereo 4 ohm at 3W output driving capability. The setup is very easy to use - simply connect a 5-12VDC adapter to the 2.1mm center-positive DC jack, then connect a digital video source to one of the ports and two 4 to 8 ohm speakers to the SPK output pins. Voilà, a display!
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 which to display.
We include a plug-in cable that connects to the 4 speaker output pins, the pins are labeled LOUT+/- and ROUT+/-. You'll have to solder your own speakers to the 4 wires
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 to HDMI converter) or SECAM.
For use with a Raspberry Pi we suggest editing config.txt to set the HDMI to native 1280x800 in case it doesn't detect the resolution properly. You can see our suggested config.txt in the Technical details tab. 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 running Ubuntu/Debian, we found it works when plugged in, no configuration required.
A power adapter is NOT included. You will need to either purchase a 5-12VDC adapter or you can use one you've already got around the house. We show the display on a bent wire stand which is not included, but you can pick one up here We may ship with a black flex cable or a white ribbon cable to connect the TFT to the driver, both work identically!

To get the best view from this display on a raspberry Pi, use this 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=-40 #overscan_right=-40 #overscan_top=-40 #overscan_bottom=-40 # uncomment to force a console size. By default it will be display's size minus # overscan. #framebuffer_width=1280 #framebuffer_height=800 # uncomment if hdmi display is not detected and composite is being output hdmi_force_hotplug=1 # uncomment to force a specific HDMI mode Group 2 and Mode 28 is 1280x800 @ 60hz hdmi_group=2 hdmi_mode=28 # This line will force the Pi to recognize the HDMI driver in video and audio mode # change to =1 to have video only 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
