Hello NXP:

    开发板的型号:phyflex-imx6-2 :  PFL-A-02-13237E0.A1/PBA-B-01 (i.MX6 Quad, 1GB RAM on one bank, 16MB NOR)
    BSP : BSP-Yocto-iMX6-PD15.3.0
    linux系统,linux-4.1.15

    出现的问题:
    1. 当uboot向内核传递的视频参数修改为video=HDMI-A-1:800x480-18 时, 连接HDMI的显示器可以全屏显示。
    2. 当uboot向内核传递的视频参数修改为video=HDMI-A-1:1024x768-18时,连接HDMI的显示器不会出现画面。 
    3. 当uboot向内核传递的视频参数修改为video=HDMI-A-1:1440x900@60 时, 连接HDMI的显示器只在屏幕的左上角显示界面,不能全屏显示。

     4. 并且目前我所知道的 只有在800x480, 1440x900 时,HDMI才能显示图像,其他的分辨率都不能显示图像。

    

谢谢!

yes, IMX6 hdmi doesn't support 1024x768, refer to the Reference Manual, imx6 hdmi supports EIA/CEA-861D, for non-CEA, we coudn't guarantee to support it.

Hello:

When I disable the LVDS interface , the HDMI interface can show

many resolutions , including 1024x768 and 800x600。

Thank you !
