wilsonh Posted May 4 Share Posted May 4 Armbianmonitor: https://paste.armbian.com/gaketoluye It seems that the HDMI output does not have any option beyond 1080P. Tried multiple monitors. The font size at uboot stage seems right but the resolution maxed out at 1080P after kernel starts. Tried Armbian 24.2.1 with 6.6.16. Could be related with this: https://forum.manjaro.org/t/rk3399-hdmi-output-for-resolutions-different-than-1080p/90644. but patches should be applied at Kernel 6.4: https://www.phoronix.com/news/Linux-6.4-imx25-Rockchip-4K Attached is the screenshot when connected with DELL 25inch monitor. Should have 2K option. diagnoses: https://paste.armbian.com/gaketoluye Thank you 0 Quote Link to comment Share on other sites More sharing options...
ryanrs Posted yesterday at 12:17 AM Share Posted yesterday at 12:17 AM I have this same issue. It is displaying 1920x1080 on my 1920x1200 old Dell LCD, when using the HDMI input. If I use an adapter to connect the RockPro64 to to a DVI-D input, I only get 1024x768, bleh. 0 Quote Link to comment Share on other sites More sharing options...
