I'm interested in using 1280x1024 res for 4:3 displays with a hdmi to vga converter cable, but I hav ...

This uImage is for OPI-2 and OPI-PC only.

I compiled a version for the OPI-PLUS also, here it is:

https://www.sendspace.com/file/2u5htd

Its only the uImage.

Your script.bin (script.fex) must have following configuration:

for 1024x768:

screen0_output_type = 3
screen0_output_mode = 4

Copy code

for 1280x1024:

screen0_output_type = 3
screen0_output_mode = 5

Copy code

HDMI IS DEAD !
Power Supply have 5V DC but 88V AC !
Problem :
Circuit AC does not be isolate since DC.
The lack of protections the ESD caused the damage the HDMI.

Hi, Jamante: I only have an old monitor support 1024*768 DVI only, should I following your steps above with below changes in script.fex file to support that monitor?
Is there any extra steps I need to follow? And do you know the steps only support Linux (Ubuntu etc) or Android OS can follow those steps as well?

Thanks!

for 1024x768:

screen0_output_type = 3
screen0_output_mode = 4

Hello Dni:
Could you kindly share the kernel source with modified HDMI resolution which supports 4:3 display, I would like to port it to Android OS.

I really need the H3 android OS support 4:3 HDMI display resolution. If you would like to discuss it further, feel free to drop me an email @ hong.roger18@gmail.com Thanks a lot!

Roger

Hi, Dni:
Thanks for your help! I downloaded your UImage for OrangePI PC and test the following resolution:

When set the mode to 1280*1024 (screen0_output_mode = 5) it works fine
when set the mode to 1024*768 (screen0_output_mode = 4) , the output is NOT 1024*768, it is something like 1792*768.

Could you kindly confirm if below configration is OK for 1024*768 or other settings are needed to get 1024*768 resolution.

Thanks!
Roger
