How to get 4k to work over HDMI with my nuc5i5myhe

[DWolf7]

I cannot get my nuc5i5myhe to output 4k on hdmi mini-DP will but verified all cables and adapters work with other graphic cards and the same monitor but not the nuc5i5myhe. Win 10 is up to date and I've updated the bios and graphic card drivers. I've noticed a post about nuc hdmi drivers but the nuc5i5myhe doesn't have a download listed. Please advise.

Your nuc does have downloads: https://ark.intel.com/content/www/us/en/ark/products/84861/intel-nuc-kit-nuc5i5myhe.html

Al.Hill,

Yes I found the support downloads, I was stating there wasn't a specific download for HDMI drivers or firmware. Looks like that does not apply to my generation of CPU.

Ho @DWolf7​ 

1. "I've noticed a post about nuc hdmi drivers but the nuc5i5myhe doesn't have a download listed." you meant DCH drivers? If yes, your are right. the DCH drivers, supports only generation 6 CPU and up.
2. The latest drivers for your NUC, you may download here: https://downloadcenter.intel.com/product/84861/Intel-NUC-Kit-NUC5i5MYHE
3. What type off video cable are you using? Are they Hi Speed Video cable ? Cable like this can be suitable: https://www.amazon.com/CableCreation-DisplayPort-Eyefinity-Multi-Screen-Support/dp/B01FM50QJC/ref=sr_1_4?keywords=minidp+video+cable&qid=1558802715&s=gateway&sr=8-4
4. Can you describe your setup?
5. Please download Intel System Support Utility: https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-
6. Please run the SSU system scan and save the results. Please attach the report to your post.

LWKSMAN,

for #2 Yes latest drivers are installed

for #3 yes mDP to HDMI adapter and high speed 2.0+ HDMI cables

for #4 nuc and samsung 27" 4k monitor - i've tried several different cables and mDP to hdmi adapters, they all support 4k with other computers but the NUC does not seem to be getting the right EDID or other info from the monitor that 4k is supported and thus there is no option in Win10 to set the resolution above 1920x1080.

I don't know what is your monitor model, so I can't give you correct ling to Samsung Support. Did you install Samsung driver for your monitor?

Im away from the display, but will share the model number. However it should not require drivers the NUC show work with any display that follows the HDMI standard. In fact during boot the display reports the bios sending 4K when the intel nuc splash screen appears. I also reinstalled win 10 and during all the instal and setup the monitor reported 4K resolution. It’s stops at the windows login page. Thus this clearly tells me it’s a windows and intel issue not working together correctly. It seems this has been a common issue but hard to find how it’s solved in gen 5 nuc.

Are Re these any intel folks watching this thread that can assist?

[DWolf7]

Samsung u28d590 and the HDMI driver on the Samsung site is installed.

I've been running some tests and it seem to be a compatibility issue with the mDP to HDMI adapters, while they work find with some graphics cards I did find another AMD graphic card that does the exact same behavior as the NUC. Very strange but will be testing Tuesday with a new mDP to HDMI cable and will update. Grasshopper out!

[LeonWaksman]

The mDP to HDMI adapter can be problematic. Better use cable with mDP and HDMI connectors installed: https://www.amazon.com/CableCreation-DisplayPort-Eyefinity-Multi-Screen-Support/dp/B01FM50QJC/ref=sr_1_4?keywords=minidp+video+cable&qid=1558802715&s=gateway&sr=8-4

Thanks for the cute quote deputy.

DWolf7, Thank you for posting in the Intel® Communities Support.

Just to let you know, Intel® does not recommend the use of any kind of adapters. This is because we cannot test all of them, so we cannot guarantee that these are going to work.

The best solution is doing a direct connection with a single cable that has the same connection type in both ends. In the following link you will find the resolution supported by the Intel® NUC Kit NUC5i5MYHE with a straight connection, please look under "Processor Graphics":

https://ark.intel.com/content/www/us/en/ark/products/85213/intel-core-i5-5300u-processor-3m-cache-up-to-2-90-ghz.html

If you are unable to use a straight connection, a possible solution is updating the graphics driver to the latest version, install all Windows* updates and update the BIOS as you already did.

If none of these workarounds fixes the issue, it is very likely that the adapter is not supported by the controller. In that case, you contact the adapter manufacturer to look for possible workarounds.
