Hey there,

i`m just building a new desktop to get in touch with 4k productions. So i decided to get a Blackmagic Quad HDMI Recorder PCIe Card to get easy access for any laptop source. This card itselfs works flawlessly. It supports formats up to 4k60 DCI (4096x2160).

If I´m adding this card in this resolution to vMix, I get the Unsupported Video Format Error. Other resolutions like 4k UHD (3840x2160) are working as intendet in vMix. But in my productions it is not always possible, to change the resolution on the notebook by hand. EDID tells there is a Resolution of 4k DCI possible and uses this as standard.

I believe the issue is anywhere inside vMix, because other Software can capture the highest resolution (Media Express, OBS) without any problems.
For any hints, where the problem can be, i would be very thankful.


Some Informations of the system:
vMix 4k Licence @ 28.0.0.42
Graphic Card in use: RTX 5070
CPU: i7 14700K
RAM: 32GB DDR5
Board: ProArt Z790 Creator
