I connected a 49" super wide curved monitor (philips 49b2u5900) to opi5+ through HDMI. I would expect to have the possibility to choose between resolutions of 5120x1440 or 3840x1080. Unfortunately I only get 16:9 resolutions. v24.8.4 for Orange Pi 5 Plus running Armbian Linux 6.1.75-vendor-rk35xx Packages: Ubuntu stable (noble) david@orangepi5-plus:~$ xrandr Screen 0: minimum 16 x 16, current 3840 x 2160, maximum 32767 x 32767 HDMI-1 connected 3840x2160+0+0 (normal left inverted right x axis y axis) 1190mm x 340mm 3840x2160 59.98*+ 2048x1536 59.95 1920x1440 59.97 How can I configure the proper resolution? I as have little experience with this kind of problems and other similar issues were years ago reported I thought to open a new topic. Thanks for any reply.

Thanks for all the answers, that certainly go beyond 'not a viable option'. The hardware is a very dedicated motherboard with a Radxa CM5 compute module (RK3588s2 SoC) and some non-standard peripherals for software defined radio reception and transmission purpose, and an Armbian OS for the CM5 in which extensive use has been made of user patches and customize-image. A large part of the end users though are not into software, and an even larger part not into Linux based software. And, as with any product, a large part of the users will not read a manual. Rather than explaining how to use 'rkdeveloptool' or equivalents to put the Armbian into eMMC, it would be much simpler to have a one time SD card insertion, wait, power off, remove SD card, and power-on with boot from eMMC. Certainly normal use of the system has to be from eMMC as it boots faster than SD. Hope this explains the motives for my question that also aimed at not re-inventing the wheel. But a ready to go solution seems not yet available. Was looking into the one-time script 'armbian-resize-filesystem'. Perhaps that would be a good place to add the functionality I am looking for and, in case booted from SDcard, do a OS copy into eMMC before the OS on the SDcard is resized to memory size. I've read that when the copy is made one must make sure that no writing goes on into the source image that is being copied, to ensure integrity of the root file system that is landing on the eMMC. Ideas welcome how and where to do a copy into eMMC from SDcard in Armbian of the yet unexpanded OS! Igor's point taken that preferably it should be as simple as possible and minimally disruptive to current standard Armbian. Basically a switch in configuration that, when set, makes the first boot process detect whether it starts from SD, whether eMMC is present, whether the switch has been set, and only then does the dd copy and ends with the invitation to remove the SD card and reboot.

I agree, I would make it a file server/NAS, print server, maybe mpd server. I have similar box and planning to use it instead of my Orange Pi PC.

Hi, I carefully reviewed your script 'armbian zram config' and found that zram is used by default, but the ko file for zram is not available. How did executing 'modinfo zram' succeed?? Amazing！！！ help
