Hello,

I am working with a imx6 dual lite digi board. I need to use a LVDS custom display.

I used the kit's display that digi provides and worked fine but when I want to use other monitors those don't work.

When I connect one of those displays It shows dark image, another display that I connect don't show anything.

 

The dtb file has the next configuration:

&ldb {     lvds-channel@0 {         fsl,data-mapping = "spwg";         fsl,data-width = <18>;           display-timings {             native-mode = <&g101evn010_1>;               /* Fusion 10" F10A-0102 */             hsd101pfw2_1: timing@0 {                 clock-frequency = <45000000>;                 hactive = <1024>;                 vactive = <600>;                 hfront-porch = <0>;                 hback-porch = <0>;                 hsync-len = <176>;                 vback-porch = <0>;                 vfront-porch = <0>;                 vsync-len = <25>;             };               /* AUO G101EVN01.0 */             g101evn010_1: timing@1 {                 clock-frequency = <68930000>;                 hactive = <1280>;                 vactive = <800>;                 hfront-porch = <120>;                 hback-porch = <0>;                 hsync-len = <8>;                 vback-porch = <10>;                 vfront-porch = <0>;                 vsync-len = <6>;                 hsync-active = <1>;                 vsync-active = <1>;                 de-active = <1>;                 pixelclk-active = <0>;             };         };     };

I changed timing@1 configuration, hactive, vactive and clock-frequency but the display It shows the same way.
I read that maybe can be backlight configuration but I put a backlight configuration but Its not made difference, I dont know if I did it well.
I have a 4.6 kernel version.
I have to use a lvds-hdmi hardware adapter I dont know if tuhis is the problem.
If someone can help me.
Regards.
