Summary0000826: [BFX-AT100] When change a resoluton from 1080i to 4k on LG tv, It is shown as blinking with green color
DescriptionHI Kerwin

I received some question from LG Electronics.
They received some question from their user.
the user is used with Smart 3 + LG TV.
The issue is when changed from 1080i or 720P to 4K or auto . some times happen from 1080i to 720p or from 720p to 1080i.
but I think it isn't related to TV. since TV already send EDID to STB . When it changed a resolution , only TVS only give a resolution to Driver.
Issue is it is shown as blinking with green color .
Here is SEC tv and LG tv. but only see it on LG tv.
LG TV model is 55SK9900KNA.
When set as 1080i, it make some issue on these days.
please check with LG tv in your side if you have LG tv.

Thanks
