More funny experiences with that kwmobile EDID emulator:
It has 16 settings, a few of them claiming to be 1080p 3D, and indeed when i select one of those, the NOC windows 10 settings show 1920x1080 with 3D. When i select other settings, the NUC does not show 3D. Great.
Interestingly, the kwmobile also has what i would call passtrough, copy EDID from sink. And lo and behold, that too gives picture with 3D, even though my (obviously wrong) logic tells me it shouldn't show any picture because it should be the same as if i wouldn't use the EDID emulator. So either i totally do not understand what is going on (very likely), or the root reason for me not getting any picture without any EDID gadget is that the marantz receiver somehow messes something up (in the EDID data ?), and the kwmobile fixes it up. It surely can't be a cabling issue, because its just a 1 ft distance NUC to receiver and i tried various cables.
The main downside of the kwmobile seems to be that it really depends on the sink to be present to do its job: Windows 10 desktop on NOC 1920x1080, full of windows. switch off receiver for the night, but keep NUC running, e.g.: because its running something. next day, switch on receiver as well, all windows are downsized, stuffed into a corner, as if the NOC had in the meantime detected what looks like a 1024x768 picture.
Now, when i stack the two EDID gadgets, NUC-kwmobile-digitus-receiver-projector, then i can avoid this problem. The digitus does provide EDID data even when the receiver is switched off, and the kwmobile then overrides the graphics modes to make the NUC believe 3D mode is supported. And i already thought i had wasted $18 on the digitus EDID emulator.
Did i say crazy EDID ? ;-)
