Hello,
I am working with a imx6 dual lite board. I was using the kit’s display that digi provides but I need to use a different display, but when I connect It to lvds connector It works but the image shows very dark.

this is The dtb configuration, I am using timing@1, I could change resolution and frequency but the image shows dark.
I read that It could be the backlight configuration but I dont know how to do that.
&ldb {
lvds-channel@0 {
fsl,data-mapping = “spwg”;
fsl,data-width = <18>;

    display-timings {
        native-mode = &lt;&amp;g101evn010_1&gt;;

        /* Fusion 10" F10A-0102 */
        hsd101pfw2_1: timing@0 {
            clock-frequency = &lt;45000000&gt;;
            hactive = &lt;1024&gt;;
            vactive = &lt;600&gt;;
            hfront-porch = &lt;0&gt;;
            hback-porch = &lt;0&gt;;
            hsync-len = &lt;176&gt;;
            vback-porch = &lt;0&gt;;
            vfront-porch = &lt;0&gt;;
            vsync-len = &lt;25&gt;;
        };

        /* AUO G101EVN01.0 */
        g101evn010_1: timing@1 {
            clock-frequency = &lt;68930000&gt;;
            hactive = &lt;1280&gt;;
            vactive = &lt;800&gt;;
            hfront-porch = &lt;120&gt;;
            hback-porch = &lt;0&gt;;
            hsync-len = &lt;8&gt;;
            vback-porch = &lt;10&gt;;
            vfront-porch = &lt;0&gt;;
            vsync-len = &lt;6&gt;;
            hsync-active = &lt;1&gt;;
            vsync-active = &lt;1&gt;;
            de-active = &lt;1&gt;;
            pixelclk-active = &lt;0&gt;;
        };
    };
};

Check LCD HRMA and see how the brightness/backlight are controlled.

Perhaps you can do something similar:
lcd_bl: backlight {
compatible = “pwm-backlight”;
pwms = <&ecap0 0 50000 0>;
brightness-levels = <0 51 53 56 62 75 101 152 255>;
default-brightness-level = <8>;
};

The V59 seems to be very good. HDMI and it has a remote. Just have a look at the back. Mostly i contains the screen size in this number. What you showed here is the connector for the Inverter for the backlight. NOT the Lvds cable. I’m not 100% sure if all LVDS cables are the same, but I doubt that.
