Hello all Just bought two 4K monitors (both are the same Samsung u28e590). Tried to get 4k on both, but failed :(

Hello all

Just bought two 4K monitors (both are the same Samsung u28e590). Tried to get 4k on both, but failed :( Using nuc8i3beh

One connected using HDMI cable - got 4k

Second - via dell adapter (https://www.dell.com/en-us/shop/dell-adapter-usb-c-to-displayport/apd/470-acfc/pc-accessories) - USB type c to display port. Using the monitor's cable, btw. This one works only on 2560 :(

 

Am I right in thinking, that I can get full 4k on both only if I use not adapter, but whole USB type c - HDMI cable? 

Or this nuc unable to show requested resolution at all?(

Tried on win 10 and hackintosh.

Maximum supported display resolution for NUC8i3BEH is 4096 x 2160 at 60 Hz from HDMI output and 4096 x 2304 at 60Hz from DP via USB C output. Your monitor supports maximum resolution 3840 x 2160 at 30Hz when connected to HDMI1 port, 3840 x 2160 at 60Hz on HDMI2 input and 3840 x 2160 at 60 Hz ob DP input. Also your USB C to DP adapter meet 4K specification. However I'm not sure that the DP to DP cable included with the monitor OK. So try other DP to DP cable or USB C to DP cable (without adapter).

I am not sure about this USB-C adapter. It is not listed as being Thunderbolt 3 compatible, which I have been told is a necessity???

I have a NUC7i5 and connected 4K TV at 60Hz using a Cable Matters Thunderbolt to HDMI USB3 Cable with no problem.

There was an issue at the time, I'm not sure that it still exists. There was No support for HDR10 I'm not sure if it was a cable or Thunderbolt issue.

Straight forward 2160 was no problem but I switched to HDMI to get HDR.

Which NUC7i5? That title describes two different NUC models and more than 6 SKUs. You really need to be more complete in your description or use the recognized acronyms. See Intel NUC Product Code Naming Convention for a description of the conventions. In most cases, the Family Code is enough. If the processor is important to the reference, you can include it. For example, i5BN.

 

Whether support for HDR is present depends upon the capabilities of the DisplayPort adapter present. The processor has support for DisplayPort 1.2 and thus HDR is included within the capability set. On 7th Gen and later NUCs, the LSPcon IC (with appropriate firmware upgrade) that is used to convert from DisplayPort to HDMI supports HDMI 2.0a and thus the HDR capability is included. With appropriately-capable adapters where necessary (i.e. where miniDisplayPort or USB-C connectors are provided), I have enabled HDR on 6th, 7th, 8th, 9th and 10th gen NUCs. Frankly, it looks like crap when not actually displaying HDR content.

It's a BNH, I guess it was a cable issue. I actually have HDR enabled all the time now using latest igfx_win10_100.7985 and have good pictures on both HDR and non HDR but it requires tweaking both on the computer (windows HD color settings) and in my case the HDMI settings on the TCL TV. I'm on the windows insider program Build 19608 but not sure if there is something different with HDR in insider builds. I do not have the "milky" picture on non HDR anymore but I'm not sure since when. Could also have something to do with my settings after firmware upgrades on the TV.
