    Hi guys,

    i got my hyperion ng 2.0 alpha 8 working tonight, but im seeing the red being captured as more of an orange.

    i sent it the hyperion red and it captures orange

    im using the following hardware:
    4K sources.

    HDMI 4k downsampler and splitter
    https://www.amazon.com/gp/product/B07VP37KMB/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

    HDMI to composite:
    https://www.amazon.com/gp/product/B01KXI8LZE/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

    USB capture card:
    https://www.amazon.com/gp/product/B0126O0RDC/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

    what am i doing wrong here?

    EDIT: it looks like its the HDMI Splitter/Downscaler that is doing it. it works fine with scaling switched off and direct into the cap device, for some reason the downscaler is messing up the red.

    thanks

    ok so after more messing around, i was using the dual outputs from my Onkyo TX686 one going directly to the tv and the other going to the splitter, i had the splitter in force 4k and both outputs set to downscale to 1080. one output went to the hdmi to rca and the other to a 2nd 1080 tv somewhere else in the house. this results in the cap card seeing red as orange for some reason

    if i change the splitter to copy 1 and put it in line with the TV everything works as expected. this is a little frustrating but it works.

    Your HDMI 4k splitter is OK, but the other components provide the problem.
    With a 4K HDMI USB grabber you can get this under control and also with better quality.

    Yes, I think the grabber has the same chip.
    You then no longer need the scaler in the splitter and then set EDID copy from Output 1 (TV)

    Thanks, this arrived today, it captures great but adds delay, is that normal or is there a fix
