Hi hiluke, I've given up on Philips and ordered a Samsung UE48JU7580.

You might want to be more specific about the system than just an "ASRock mainboard".

Specifically, a system using the Intel J3455 processor, since that is the source of the video output.

Or better, the Intel® HD Graphics 500, which is what you are using, and the Intel graphics driver for HD 500 graphics. The OS type and version are also important, since the Intel graphics driver can/will be different for each type and version.

Otherwise, my "ASRock mainboard" can display those files over HDMI fine. But that PC has zero in common with yours.
It's true, my question was quite unspecific... back then I was very desperate to find an answer. And I was angry that none of my components (HD500/LSPCON/TV) were telling me what they were doing. I'm an IT dev since 15 years, so I love debug output ;)

  • I would now say that any HD graphics newer than 500 can do DP 1.2 and UHD 60Hz 4:4:4 8bit
  • the LSPCON from MegaChips (onboard ASRock/Gigabyte etc) and ParadeTech (external Club3D) don't seem to interfere
  • if the HDMI cable is quite short the quality seems to be irrelevant
I've heard that some TVs convert all inputs to YCrCb 4:2:2 for internal processing... I'm afraid my Philips TV falls into that category.
What TV are you using?

There's now a 1.66 for the LSPCON. I could flash it without any issues.

The 1.66 firmware is also now released on the ASRock support page.

Thanks hiluke

I wonder why they only list to update there.
The J3455-ITX, J4205-ITX etc have the same LSPCON.

Currently, it seems that 3840x2160@60Hz is only working for me, with HDMI firmware 1.36 and Intel driver 21.20.16.4627
4:4:4=OK on my system with Win10pro version 1703 build 15063.250.

Intel driver 4629 refuses 60Hz again.

Every other HDMI firmware from Asrock fails with my system at 3840x2160@60Hz with Intel driver 21.20.16.4627.
