DietPi

on a 4k TV with 2160p, photos look terrible. i have tried many photos too. photos look rough or jagged, not smooth.
text and MATE gui looks fine. any idea how to improve picture quality?

order of operation: 1. TV on first 2. power odroid c2 via usb 3. TV shows nothing but a black screen. i dont even see lines of codes scrolling through and onto the MATE desktop BUT then 4. i turn TV off and back on, then i can see desktop and icons. no more black screen. boot.ini has: setenv hpd &qu...

i found this command: but then gives error:
autodetect FAILED

any idea?
please help

so it looks like CEC is already enabled by default because my 4k TV can recognize the odroid c2 connected. HomeAssistant cant control the TV without libcec. how to install it properly? would these codes found here work? can i copy verbatim into dietpi terminal? https://www.raspberrypi.org/forums/vie...

tried ubuntu and it gave me pretty much same problem. went back to dietpi clean install. chose Mate, and autostart in desktop mode with autologin. created my script and made it executable. then add it to the autostart application on the top menu and now it works like a charm! hope this helps someone...

i finally figured out FEH only works in the desktop GUI. so how do i run this simple feh_start.sh containing these commands? xset s off xset -dpms xset s noblank feh --quiet --fullscreen --borderless --hide-pointer --randomize --slideshow-delay 30 /media/usb/ after searching, i found this https://ww...

the Odroid C2 just arrived yesterday. i was able to get it to boot into desktop GUI. i got feh installed and it opened photos on USB drive fine. BUT this does not work on the C2 obviously: sudo nano /home/pi/.config/lxsession/LXDE/autostart i set up the custom.sh autostart and filled in these: @xset...

this is the full code i got working for the raspberry pi. it will play whatever is on the USB drive continuously. havent tried with the PIR motion sensor yet. just ordered the TV and odroid C2. waiting for arrival. same codes should work on C2 right? sudo apt-get update sudo apt-get upgrade sudo apt...

4K TVs are so cheap now, i just bought a 55 inch TV from walmart for $280 with tax. has anyone tried DietPi with C2 on a 4K TV, with a PIR motion detector, as a picture frame? ideally, the PIR motion detector will turn on TV via HDMI CEC when motion is detected. TV stays on for 10mins. if no motion ...
