Product Description

Yes, this is an adorable small HDMI television with incredibly high resolution! We tried to get the smallest possible HDMI/VGA display with high-res, high-contrast visibility. The visible display measures only 7" (17.8cm) diagonal, and the TFT comes in an enclosure with HDMI, VGA and Composite inputs. The display is very easy to use - simply connect the included 12VDC adapter to the 2.1mm center-positive DC jack, then connect a digital video source to one of the ports. Voila, a television display! There's some little buttons on the front that let you enter a menu system for adjusting brightness, color and contrast. It auto-detects which input you have and switches to that one or you can 'select' from the menu which to display. It comes with a basic stand (shown) and there are four 'mounting thread' holes in the back in a 75mmx75mm square and you can use M4 screws to attach it to an enclosure. There's also a "Camera Mount" 1/4-20 hole in the bottom so you can attach it to a camera-ready mount. 

We also have a version with built in 3W speakers so you can do a full A/V setup check out that 7" display with speakers here. 

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 as in the technical tab. 

For use with a BeagleBone black, we found it works when plugged in, no configuration required. You may need a mouse/keyboard to keep the Bone display from going into 'sleep mode' 

A power adapter is not included. Any 9 to 12VDC adapter will work nicely: we prefer 9V DC. Video will work with 5-12V but the audio amplifier requires 9-12V so if you want the speakers to work, 9V is best. Check the technical tabs for current draw at various voltages.

  • Power with 5-24VDC
  • 700mA power draw at 12V
  • 16:10 display ratio
  • Resolution: 1200 x 800
  • Visible area: 150mm x 95mm 16:10
  • Brightness: 400cd/m2
  • Contrast: 800:1
  • We opened up one of the displays and found an HSD070PWW1 inside, we expect that all of TVs have this display or something similar
  • Auto-detects between VGA, HDMI and Composite
  • Display plastic case dimensions: 180mm x 130 x 30
  • Weight (excluding power cable): 290g/10.2oz
  • Not HDCP compatible - it cannot be used with 'secured' HDMI sources

To get the best view from this display on a raspberry Pi, use this config.txt:

[code]

# 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 #overscan_left=-40 #overscan_right=-40 #overscan_top=-40 #overscan_bottom=-40 hdmi_drive=1 hdmi_group=2 hdmi_mode=28 # 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 (this will force VGA) #hdmi_group=1 #hdmi_mode=1 # 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

You alternate between pressing the MENU and +/- buttons. 

Pressing MENU the first time will bring up the box that shows the options. Pressing + or - will move the selection point from one option to the next. 

Pressing MENU a second time will select an option and let you select the specific value you want to change. The selection marker is a thin blue line under each option. Pressing + or - will move the selection from one item to the next. 

Pressing MENU a third time will select the specific value you want to change. Pressing + or - will increase or decrease the value, or switch between ON/OFF options for things like automatic shutoff and bluescreen display. 

Each list of options has an 'Exit' item at the end, and you can move back to the previous selection level by pressing MENU when that item is the current selection.
