RPi 5 inch HDMI LCD

Bought a 5″ HDMI LCD screen for my Raspberry Pi, but it wasn’t working until I made some changes at /boot/config.txt file to force 800×480 screen resolution, edit /boot/config.txt and modify these lines:

hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0

Raspberry Pi 5inch HDMI LCD

 

Optionally to enable support of MJPEG, VP6, VP8, Ogg Theora & Ogg Vorbis, add these lines:

start_file=start_x.elf
fixup_file=fixup_x.elf

60″ TV on the ceiling

To use your chromecast without a television? All you need is a mini LED projector with HDMI input (you can get it at US$60 or less), and a metal book stand (Yes, metal book stand, and this might be the best thing you ever do with a metal book stand, to stand a projector ^_^)

And enjoy your movie with 60″ screen on the ceiling 🙂

My first contact with Raspberry Pi

My new toys = berry + bread, lol

Raspberry Pi, solderless breadboard, HDMI, jumper, LED, switch, MicroSD...

Attended Raspberry Pi workshop today, learned Raspbian, Python programming, solderless breadboard, 7 segment numeric LED display…

One step further in exploration, one step closer to invention.
