UHD 60Hz 4:4:4 HD500

Hi, I've been trying to get UHD 60Hz 4:4:4 8bit to work for 2 months now. Please help me

Here's my setup:
- ASRock J3455-ITX FW 1.2 with Intel HD 500 (Apollo Lake, HEVC)
- onboard LSPCON MegaChips MCDP2800 FW 1.61 (DP 1.2 to HDMI 2.0)
- Club3D 3m 4K HDMI cable
- Philips 43PUS6101/12 (HDMI3 set to YCrCb 4:2:2/4:4:4 mode)

I've tried Windows 10 (newest drivers) and Ubuntu Linux 16.10. The best I can do is UHD 60Hz 4:2:2. I've done days of research and think that all four components should be able to do 4:4:4.

I've asked Intel to add more controls to the HD graphics control panel but I wonder if they will ever implement it (RGB/YCrCb4:4:4/8bit).

The EDID of my Philips TV is total crap (the recommended resolution is 1920x1080, haha).
Is there a chance I can force 8bit mode and YCrCb 4:4:4 with CRU?

thanks
