Hi. Could you please share your script.fex ?
This would be a lot helpfull. May be there is some differences between your and my file (i`ve tried to enable hdmi-dvi and change a lot).

With default script.bin (720p50) and new hdmi_para nothing changes. With modified script.bin (720p60, disabled tv_out, hdmi_enable = 0 in [audio] and some other params) it is working, but so bad. Picture came for split of second and very glitchy. But it worls somehow

Thank you in advance.

Also for everyone: please share your script.bin/fex files.

my script.fex http://pastebin.com/rrmHGgke

pll_video is set to 432 because I modified the 720p resolution in kernel sources to 1280x1024 and it seems that pll_video needs to be a multiple of the dot clock frequency (108MHz for 1280x1024), otherwise it should be same as default.

I tried two adapters and a cable HDMI to DVI: none of them worked.
HDMI/HDMI cable and HDMI monitor work ok.

just want to share my experience in getting my Orange Pi PC work on HPW1907 montor with DVI connection.

1. i modified the script.fex to include the following:
     a. under [hdmi_para], i have included the following lines:
           hdcp_enable = 0
           hdmi_cts_compatibility = 1

     b. under [boot_disp]
          screen0_output_type = 3
          screen0_ouput_mode = 4
          screen0_output_type = 3
          screen0_ouput_mode = 4
          fb0_width = 1440
          fb0_height = 900
          fb1_width = 1440
          fb1_height = 900

Note: the 1440 and 900 is the recommended maximum resolution that my HPW1907 monitor can support.

my hardware set-up is:
    orange pi ------HDMI cable -----HDMI to VDI Connector----HPW1907 DVI Port
my OS is: OrangePI-PC_Ubuntu_Vivid_Mate.img.xz

a good reference to read on how the srcipt.bin (or script.fex) can be found in this link:
     http://linux-sunxi.org/Fex_Guide#.5Bdisp_init.5D

you need to install a sunxi tools in order to convert the sript.bin to a text file (script.fex) to modify  the parameters inside it.
    https://github.com/linux-sunxi/sunxi-tools

if somebody needs a more detailed stepts, just drop me a note.

Enjoy playing with your Orange Pi PC!!!!

If you can connect it to another monitor, or if you can connect via ssh, download update_kernel.sh from Mega,
copy it to /usr/local/bin and make it executable, then run
  1. sudo update_kernel.sh
Copy the Code
Follow the instructions to select hdmi->dvi as your monitor type.
