Nope had a bunch of HDMI cables and adaptor laying, checked it is HDMI sync issue or poor soldering of hdmi connector on the board. @TeroDada as you use usb to usb for power, that means you giving only 5v0.5A to the box, is it sufficient? Normally adaptor used are 5V2A. With 0.5A box behaviour is always bad for me. Box need minimum 1A adaptor for smooth function.

@jock@fabiobassa and others Thanks for great support for RK322x. I had x96mate with h616, after booting arch, its HDMI gave up on me, so after reading your post got the RK3229 box. I don't intend too use as a desktop but as a kiosk. Mainly I use chromium, nodejs, and mpv/ffplay/cvlc (anyone) Box I got is rk3229 with nand, so teste 3 legacy images, one without DE and two with xfce from OP. Everything works as expected on horizontal mode. As I need mpv to run smoothly, installed media package by @jock after installing media support, i no longer able to rotate my display, before installing the media support display rotate worked. cannot use xrandr to rotate also option in settings ---- display, rotate option is not there. DISPLAY=:0 xrandr --output HDMI-1 --rotate right any clue how to sort this out ?

Update 2 - Somehow HDMI is loosing signals every 2sec, even on Android. So no more testing from my end.

Update -- While first installation I did not expand my SD card, so installing script gave me successful msg but my SD card was full and due to which screen went blank on reboot. 2nd time before doing any updated I expanded SD card, option is available in "start" script. Installation of EOS took 2-3 tries, might be due to large files download , network connectivity etc.. after 3rd time lightdm was not loading, had to install it manually after this, got the GUI login screen, but could not login. with lightdm , gtk greeter was missing, then xfce goodies was not installed with EOS scripts. did all these those thru pacman -S after this, I was able to login and now I got full Desktop on H616, I can play 720p on CPU, 1080p was glitchy, Apache, Chrome, nodejs , ffmpeg etc was installed without any issue. (these are required for my project) Did not test anything else. What not Working 1- WiFi 2- Audio 3- GPU (not sure) 4- YouTube not starting play due to audio issue. Don't know how to shift from SD to eMMC, will have to search for this now. (posted these finding on EOS forum too) To DO - 1- SD to eMMC 2- Trying to put Armbian on SD (might be mix and match)

I had X96 Mate from long time, which is 4GB/32GB with H616 CPU, (It is almost same as Tanix TS6s) Tried many images from orange pi for same chip, none worked perfectly. Found out Sunix Linux community got support for H616, but they don't build full OS images, After hell of searching found a repo from https://github.com/warpme/miniarch He hosts MiniArch SD card image which works on many devices, from same link got SD card image for Tanix tx6s which also worked on x96_Mate (both got H616) Here is the file I used - https://github.com/warpme/miniarch/releases/download/20230106-6.1.5-g78293cd3/MiniArch-20230106-6.1.5-board-h616.tanix_tx6s-SD-Image.img.xz 1- Wrote img to SD card using Etcher 2- Inserted SD card in Device 3- Powered ON the device and it Booted from SD card 4- followed update instructions on GitHub Repo. 5- Rebooted after all updates, 6- Basic Arch was ready to be used Here USB keyboard , LAN, HDMI worked normally. After reboot, logged in as root, and ran "start" command, Now here selected option 5, which is install EndeavourOS Process just ask you Yes/No questions, then you can select your DE, location etc. Automated script downloaded bunch of files and started its installation. Got the message that installation is done successfully and came back to terminal. Rebooted from terminal After this point got only blank screen , dont know it is still booting without HDMI or not So need to revert back to step -1 writing basic image to SD card. And this time sticking to terminal only. all this process is done on SD card only, and android on eMMC is safe .
