Hyperion -HDMI Splitter – Video not smooth – horizontal line in mouvement scene

Hi guy,

I don’t know what to do. Here is my problem.

I use a splitter behind my AVR to split the signal to the TV and to a HDMI-Composite converter. (for Hyperion ambilight)

Since i had to do this, i had to use the Full screen windows mode otherwise i lost HDMI signal when the splitter is plugged. I think kodi (Windows 7 ?) detected that there are 2 screen plug and then black screen.

But when i introduced the windows mode, i see that the movie picture is not smooth, and i suspect possibly refresh rate problem.

I tried to change different parameter :
– force 50 hz en windows and kodi
– activate interlacement mode in kodi, change render method (bicubic by default)

i don’t know what to do, i always have an horizontal line when there is a movement in the video (live tv, hd video, sd video, …)

If anyone has similar configuration, i’im interested

I run kodi 16.2

Thanks
