A little of update: I installed desktop environment (using armbian-config) on both image provided by @Igor and the one downloaded from the board page (Armbian Xenial 5.85 stable, but with kernel updated to 5.10 using armbian-config). In both cases I'm having Armbian desktop environment working fine, though the resolution is still 1024x768. I've read this instruction and added line setenv video-mode sunxi:1920x1080-24@60,monitor=dvi,hpd=0,edid=0 to my boot.cmd file, recompiled it to boot.scr and rebooted twice, but it gave no difference. Is it possible to change resolution manually any other way? I assume this behavior could be accounted as a proof that my board experiences some hardware fault, while it's being handled differently by legacy and mainline kernel. Guess not really much can be done at this point.

I tried this image and not really anything changed except now screen resolution is 1024x768@60p. I read through the logs and it seems that the board fails to auto-detect parameters of a monitor attached. Logs: http://ix.io/1NN5 I guess at this point it's not a software problem, but I'm curious what could be the reason after all, considering that the board used to boot just fine. I have a bold assumption that it could be related that few days ago there was a power failure with short period of over-voltage at the building I work in so it may be the reason (or may not, I don't really know). Anyway thanks a lot for your help!

Thanks for your answers. To NicoD: I just tried Armbian 5.59 Ubuntu Xenial on a fresh new SD card. No difference. To Igor: I guess I wasn't clear in my description of current and previous behavior. Previous behavior: Armbian Xenial Desktop: 1920x1080 display U-boot log output on HDMI, then 1920x1080 OS boot log, then desktop environment. Armbian Bionic Mainline: 1920x1080 display U-boot log output on HDMI, then 1920x1080 OS boot log and login promt. Current behavior: Armbian Xenial Desktop: No HDMI output during U-boot (can track it through UART), then this same-color on HDMI. Armbian Bionic Mainline: No HDMI output during U-boot, then 1280x720 OS boot log output on HDMI, then login promt. I understand that Android bootloader is different from U-boot and Armbian, but I guess the fact that the SBC boots at all may mean that this behavior not a complete hardware failure. Maybe I guess wrong. I already tried three different HDMI cables (proved to work with Raspberry PI and Win10 PC) and two monitors, though both of the same model. Going to try monitor of another model. Edit: tried another monitor. Same one-color image. Monitor detected that the image is 1280x720@60Hz

I encountered a very strange boot behavior on OrangePI Plus 2E. When I boot from SD card with the desktop Armbian image, I'm having just an input of some color on HDMI (photo attached). No U-boot output on screen, but considering UART output both U-boot and system boot with no errors (log file is attached). Boot with the server Armbian image goes just fine, except no U-boot output on screen (only on UART) and screen resolution is 1280x720, while native resolution for the display is 1920x1080. Until recently everything worked just fine with both desktop and mainline images, and U-boot giving proper output on screen in 10920x1080 resolution. What I tried so far: 1) Rewrote desktop image on same SD card after full formatting. Didn't help, nothing changed. 2) Moved to NEXT kernel on mainline image, reinstalled U-boot. Didn't help, still no display output in U-boot and resolution stuck on 1280x720. What I'm going to try now: - Write both images on new SD cards. I have a default preinstalled Android image on eMMC and it boots just fine, but I'm not sure what that means to my problem. Guess it's not a failure of HDMI interface at least. Would appreciate any help on this problem.
