C128: Eye of the Beholder - dual monitor capture 

Haha, good one 👍

My problem in the end was a setting in the RGB2HDMI device I use to convert C128 80 column output to HDMI. That device has a gen-lock setting to lock the device to a specific frame rate to avoid dropped frames when the input source is slightly deviating from exactly being 50 Hz (like with most retros). For some reason which I myself do not fully understand however, that setting caused the EotB VDC screen to completely blank out. Disabling that gen-lock setting solved my issue. Do not ask me why the one works and the other not ;-) What I use for dual screen capture: - RGB2HDMI device for VDC 80 column to HDMI conversion - Framemeister xRGB Mini for VIC-II 40 column to HDMI conversion (using an S-Video cable). Also sometimes use a Retrotink 2X Pro in other setups - The audio output from the S-Video cable is not fed to the Framemeister but to a Behringer Xenyx Q502USB mixer, which outputs the audio signal over USB to my PC - Two times an Elgato CamLink 4K to connect the two HDMI cables to USB on my PC and capture both the HDMI signals - OBS software on the PC to bring both HDMI signals and the audio signal together in one video

Because I had no clue yet how to at that time 😉was merely looking at it from a technology demonstration perspective, still have to find time to really dive into actually playing it.
