It would be great if it would be possible only to have the backlight on when using the grabber or Kodi, and not when using the static colors/effects.
Using the backlight during movie playback would make it more "ambilight" like and make the delay of the LEDs when using the grabber more acceptable.

How come that the LEDs are on at top and bottom even though black border detection is turned off?

No the only image processing that can delay the image noticeable is motionenhancement and this is worse too look at than the delayed LEDs o_O....
Almost seems like I am the only one with this issue.... strange.

Too bad that I am not into image processing. Enabling some processing on my tv will instantly delay the shown image with what is needed... and more!

This is without Black border detection enabled!. There is still a delay when sudden changes in brightness.

I have now tried disabling Black border detection without any difference in delay.
Should I still see ambilight at the top and bottom with this disabled?? I thought not but it still does show.

Could I just try to disable Black border detection and see how the LEDs on the side react?

I think it is the same for all ratios.

Yes no difference on Pi3. It is a very small delay but very visible when watching real time. I have some video but not able to upload it here.

Hi Tociek
I have tried to set size decimation as high as 20 but without any real effect on the delay. I have also tried to set resoultion to 240x192, also without any effect.

Hi Dirk
Thanks
Unfortuneately I cannot see any difference with these settings.

I thought so but maybe some adjustements in grabber settings in Hypercon or another/better grabber type or... could help.
I have tried with or without smoothing without any noticeable effect.

I have a lightberry 4K kit for RPi2 and have noticed that the LEDs have a little (but unaceptable) delay when reacting on sudden changes in brightness when using the external framegrabber. I have tried both the USB and GPIO version with same result.
When using KODI (or rasplex) direct the delay is much smaller and acceptable but I want to use Plex on ATV4 so this in no option.
I guess it could maybe be a hardware thing with the grabber delaying the signal a bit while grabbing???

Does anyone experience the same issue and maybe even have an idea what to do?

Hi unfortunately I cannot get rid of the delay of LED reacting on sudden brightness change. Only by using KODI without a grabber helps

I have now tried some more and it seems that most settings are stored and shown when Hypercon is shut Down and restarted.
Only "output", "baudrate" and "delay" seems keeps showing default values.

Okay I will try to use these settings and see how it goes

Anyone with a solution?
