LCD with RDK demo

Hello,

I am using Mistral EVM DM8148 io expansion revD with LCD. 
I already run the decode-display demo with HDMI, but on moving to DVO2, I have problems.

I added custom display of 800x480, but on changing to this resolution (using the demo menu), I see flickers in display. On trying several resolution I see that XGA resolution is stable (but there are missing colors).

Is there some other change I need to do when using RDK (except adding custom resolution) to support output with LCD ?

Thanks

Ran

    I am not familiar with  DVR RDK but you could check is your timing setting are correct.

    Are you see this only when the decode_display demo is running?

    Best Regards,

    Missing/incorrect colors are usually due to incorrect color format settings. e.g. YUV422 when connected to a 24 bit RGB display.

    Make sure that the color format, depth and settings are correct.
