Hi Guys

I’ve recently bought a new 4k TV – “LG OLED65E6V”

Have have HTPC – Gigabyte BRIX GB-BXi7-4770R.
The little HTPC have the following specs:

Intel^® Iris™ Pro graphics 5200
Intel® Core™ i7-4770R Processor
HDMI 1.4
mini Displayport 1.2
Windows 10

So I figured, if I want to have 3840×2160 @ 60hz from the HTPC to the TV. I needed to use the mini DisplayPort with a HDMI2.0 adapter, and that is why I got hold of a CAC-1170 adapter. Plus a new HDMI2.0 cable.

But I’m stuck. And hope you guys can help me out.

Here is what it can do.
3840×2160 @ 30hz
1920×1080 @ 60hz

But not
3840×2160 @ 60hz – The TV just goes Black, until the Grafics software reverts back to the resolution it came from.
The more I read about my problem, the more i think it has something to do with the color depth 4:4:4 thing, which I don’t know much about.
All I know is, that I used to able the change the color depth in windows, but it seems to stock at 32Bit.
Do you guys think this is my problem, or could i be something else that I missed ?

Any advise will be much appreciated 🙂

Regards
Simon

Hi DarkHelmet,
Setups with TV’s normally work best by making a custom resolution, in this case for: 3840*2160 at 60 Hz with Timing Standard set to CVT-RB (Reduced Blanking ). Many LG TV’s also need to have features like “UHD Color” or “PC-Mode” manually set to “On” or “Enabled” for the HDMI 2.0 port in use. Please make sure the HDMI port of the Screen/TV supports 4K 60 Hz, often not all HDMI inputs support that.
Setting custom resolution in the Intel Grpahics Software shoudl be something like this:

Open Intel Graphics Control Panel, Chose “Custom Resolutions” (left bottom option). It will asks you if you wish to continue; YES.
Standard the “Basic” setting is shown, click on “Advanced”, check on left bottom if the correct screen is selected, Fill in; Width 3840 ; Height 2160 ; Refresh Rate 60 ; Timing Standard CVT-RB for use with TV (and for use with Monitor you can leave that on “Auto”); and click on “ADD” on the right bottom of the window. Now this resolution I added to the system and can be chosen. Go back to “General Settings”(left top) , it will show the basic options and here you can now choose the 3840×2160 resolution and 60Hz.

Insert Image Size must be less than < 5MB.
