Intel 5500 conecting to 4k TV

[CButl1]

I have an Intel 5500 connected to a Sony x830c 4k TV. When I use the default settings of 3840x2160 at 30hz it works fine. However, the TV does support 4k @ 60hz. When I create a custom resolution at 60hz, the TV goes dark and will not run no matter what timings I select. I tried to create a custom 4k res at 30hz to see which timings work, but this does the same thing no matter what timing I select. It is possible that the TV is expectiing whatever is being sent on the base 4k 30hz signal. Any idea what that is and how I would replicate it @ 60hz?

Thanks
