Is anyone using an HDMI 4k splitter with their Ultimo 4k and 4k TV? I can get a picture on my TV using all the resolutions in the A/V setup Mode except the 2160p mode. If I connect the Ultimo 4k directly to my TV using just an HDMI cable then I get a picture. But no picture when I add the 4k splitter. I`m using Blackhole 3.0.5.
