Can you get an EDID information from your WideScreen LCD?
We actually need a modeline in the EDID.
Refer to this wiki to get the information.
https://wiki.odroid.com/common/hdmi_how ... -pc_ubuntu

For example,

Code: Select all

  480x1280 (0x6f3) 56.400MHz +HSync +VSync *current +preferred
        h: width   480 start  580 end  620 total  720 skew    0 clock  78.33KHz
        v: height 1280 start 1290 end 1292 total 1302           clock  60.16Hz

First of all, can you share the picture that the screen doesn't work? It's a black screen?

In the case of android, it's some complicated. You have to edit a kernel.
The following process is needed to get the screen to work in Android.
1. Get the EDID from your 480x1280 LCD on Ubuntu. https://wiki.odroid.com/common/hdmi_how ... odroid-xu4
2. Make custom EDID binary file. https://wiki.odroid.com/common/hdmi_howto/custom_edid
3. If it works well the LCD on Ubuntu, add the EDID information to the android kernel.

Can you please share the picture of your display how it does looks like? Otherwise, it's not easy to know what's exact problem you have.
