@jamante @dni hi, did anybody really test 1024*768 with HDMI2dvi converter?
Edited by xiaoli at 2015-12-2 21:56
the resolution is required for my business. If anybody has solution, pls drop me an email. I d like to pay for your efforts once it works.
I just tried to addhdmi_cts_compatibility = 0to the fex file and interchanged script.bin using a script I've written the last minutes: http://pastebin.com/5GLU7FgV
Then installed fbset and added
fbset "1024x768-60"to /etc/rc.local. Now I get 1024x768 on my display (its native resolution is 2560x1600), but the HDMI resolution still seems to be 1920x1080 and colors look a bit strange:

Hi,
sorry i cant test it anymore, because my hdmi is also dead :(
But for me it worked with a hdmi2vga converter in 1024x768 and 1280x1024 with my kernel and script.bin.
I uploaded my latest Kernel one more time, maybe the other one was not the actuell one...

I tried it with your kernel and 1024x768 settings:
disp_init_enable = 1
disp_mode = 0
screen0_output_type = 3
screen0_output_mode = 4
screen1_output_type = 3
screen1_output_mode = 10
fb0_format = 0
fb0_width = 0
fb0_height = 0
fb1_format = 0
fb1_width = 0
fb1_height = 0
hdmi_used = 1
hdmi_power = "vcc-hdmi-18"
hdmi_cts_compatibility = 0
It gets closer :)

I have tried your image, the output is 1280*768. It seems the 1280 cannot be changed to 1024, maybe is is because HDMI supported resolution is 1280*720, there is not 1024*xxx supported in HDMI spec. Any idea?
Thanks!

well, maybe its because of hdmi2dvi...
with my hdmi2vga adapter its definitly working with this kernel...
what is the value for pll_video in your script.fex?
try setting it to
pll_video = 432
or try setting it to
pll_video = 260
i cant remember :-)

I rely on loboris' settings (except of dvfs entries since I don't like overclocking/overvolting): https://github.com/loboris/Orang ... pi_pc.fex#L163-L169

Hi Dni:
After change the PLL video to 260, it works ! The orange PI PC can display 1024*768 resolution through the HDMI to DVI converter without any issue. Is it the PLL video equals to the Pixel clock*4 such as 1024*768's pixel clock is 65, so the PLL_video is 65*4=260?
Really appreciated your help! Thanks a lot!
