Hi, I'm new here.

My first post is already off topic, sorry... but I'm so happy to find this many people that also have one of the ASRock boards.

Is there anyone here that can do UHD 60Hz 4:4:4 8 bit on a HDMI TV?

I'm using the usual test patterns: http://cellarcinema.info/temp/uhdtest.zip (WITHOUT scaling, on W10 it's 'right mouse button' + edit)

My setup is: J3455-ITX FW 1.2, LSPCON FW 1.61, Club3D 3m 4K HDMI cable, Philips 43PUS6101/12 (HDMI3 with 4:2:2/4:4:4 enabled)

With Windows 10 I get the following results:
ChromaRes.png... shows 4:2:2
TextTest_1920x1080.png... red/yellow text is not vibrant, red-on-blue text font not pixel perfect
TintBlueRGB.PNG... the word red/magenta looks like 3D

Reducing to 30Hz doesn't help im my case, but a FullHD Monitor connected to the DVI port works fine (4:4:4 mode).

I'm a Windows user, but would also like to here if it can be done with Linux.

I've tried 4 TVs, 5 HDMI cables, different firmwares, drivers and custom resolutions... I'm starting to lose hope.

I'm trying to get Intel to expand the features of the HD graphics control panel (force YCbCr 4:4:4 or RGB). https://communities.intel.com/thread/111279

thanks

Just verified that your ChromaRes.png shows 4:4:4 in UHD@60Hz with my ASRock J4205, BIOS 1.20, Win10 Pro, latest Intel Gfx driver 15.45.14.4590 connected to Sony Bravia KD-55XD8005.

So no idea what's wrong with your setup, it should work.

Edit: hope you're not doing something stupid like looping through legacy AV receiver which downgrades your HDMI 2.0 output to HDMI 1.4 or something similar...
