having HDMI issues with new V3 install (4k sony PJ)

[mcg]

Hi guys,

I seem to be having issues with my XMC-1 (V3) to projector run. I'm currently using this (https://www.monoprice.com/product?p_id=21566) cable. Sometimes I get an image, but mostly I don't. I guess the run is about 30 ft. My projector is a Sony VPL-285ES, which is a 4k projector.

Any ideas?

(It seemed to work after one hard reset where I unplugged the XMC-1). But I can't seem to replicate the success or identify why it works when it does.

I use this cable with my Marantz after trying several different HDMI cables to give me full 4K HDR

I wouldn't think that cable would be the problem, can you try the other HDMI input of the projector and/or the other HDMI output on the XMC-1.

XMC output doesnt seem to be an issue. I'm going to tru the other input on the projector. I would also think that if the cable works some of the time, if will work all of the time.

Does it works with some content and not with others?  IE 4k hdr versus 1080p?

Just because it worked before does NOT mean it will work now especially if you are trying to push a 4k 60 4:4:4 signal.

Big difference in bandwidth needed. (2x depending on previous link setting before upgrade)

Cables that worked at 9Gbs (4k 30 4:2:0) very often struggle at 18Gbs (4k 60 4:4:4)

Another questions since you are running a Sony projector like I am. The Sony 285 (and my 385) can only handle 4K 24Hz, 4:4:4 HDR. So if you using say an apple TV at 60Hz 4K HDR 10 bit your projector will say something like frequency out of range. Just a thought.
