Sabaat - am I understanding correctly that you where going directly from the splitter to the RCA adapter? Is that a sustainable setup (assuming you have it working now)?
I kind of have the feeling that your converter may have burned out because it was being forced to run 4k@60 - I have that same one and I believe it only supports the HDCP1x standard where 4k@60 requires the HDCP2x standard. Purely speculation.
I'm trying to make this work with my setup, but the splitter I tried thus far has no edid management and forced my resolution (I'm using a shield TV) to 1080p.
I did however grab a little gizmo that is supposed to downscale a 4k@60 signal to 1080p@60 (which is compliant with HDCP1x), but dumb me didn't realize I need a splitter with edid management to actually use the feature the way I intend. The only problem is the splitter advertised to work with it does not advertise as supporting CEC, so I am a bit hesitant to grab it right now.
I ended up removing the grabber, splitter etc from my setup cause it did not work perfectly for me. I was unable to find any cheap solution that would work with HDR and hence I am using the Windows Screen Grabber ( that I am working on: https://hyperion-project.org/t…dows-screen-grabber.1018/ ) with my PC.
The splitter I linked does support CEC and EDID management. The TV will also recognize it having ARC capability. However, ARC will not work. One thing that I learned while playing around with these things is that EDID management is that the splitter will never act as a signal convertor so if you connect two devices to it with different supported resolutions, one will not work.
