The Z-turn Board HDMI output is 1280 x 720. I need connector it to VGA monitor. I have HDMI-to-VGA converter, but the VGA can not display. How can I modify it to 1024 x 768 VGA format?
Answer
You can modify arch/arm/boot/dts/zynq-zturn-x.dtsi file,
videomode=1024x768, videomode has specified resolution. Recompile devicetree, copy
it to SD card and reboot again.
