dragonlost Posted February 26, 2019 Posted February 26, 2019 Hello ! I bought this screen recently: https://www.seeedstudio.com/10-1-inch-1200-1980-HDMI-IPS-LCD-Display-p-2863.html I tried to connect it to my Tinkerboard but could not get an image. On an raspberry I have input specific display settings in the configuration file. hdmi_drive=2 hdmi_mode=87 disable_overscan=1 # 10.1 inch hdmi_timings=1200 0 100 24 52 1920 0 65 4 25 0 0 0 60 0 169000000 0 max_framebuffer_width=1920 max_framebuffer_height=1920 display_rotate=3 framebuffer_width=1920 framebuffer_height=1200 By cons I do not know how to do with the tinkerboard. same problem on Nanopi-M4
dragonlost Posted February 27, 2019 Author Posted February 27, 2019 After a lot of reading, I realized that I had to patch the u-boot. By cons how to do?
Azq2 Posted March 21, 2019 Posted March 21, 2019 I have same problem. You have two ways: 1. Try set timings manualy. Find in /var/log/Xorg.0.log right modeline and add it to xrandr. # CVT xrandr --newmode "1920x1200_cvt" 193.25 1920 2056 2256 2592 1200 1203 1209 1245 -hsync +vsync xrandr --addmode HDMI-1 "1920x1200_cvt" xrandr --output HDMI-1 --mode "1920x1200_cvt" # if not working - GTF xrandr --newmode "1920x1200_gtf" 193.16 1920 2048 2256 2592 1200 1201 1204 1242 -HSync +Vsync xrandr --addmode HDMI-1 "1920x1200_gtf" xrandr --output HDMI-1 --mode "1920x1200_gtf" # or you can find right timings in /var/log/Xorg.0.log 2. If not working - try my pull request for 4.4 kernel: https://github.com/armbian/build/pull/1317
