According to Intel Stats:
The NUC7i7DHNE has this output
https://ark.intel.com/products/130393/Intel-NUC-Kit-NUC7i7DNHE Intel® NUC Kit NUC7i7DNHE Product Specifications
Dual HDMI 2.0a, 4-lane eDP 1.4
But the ARK for the i7-8650U CPU has this contradictory spec
Max Resolution (HDMI 1.4)‡ 4096x2304@24Hz
https://ark.intel.com/products/124968/Intel-Core-i7-8650U-Processor-8M-Cache-up-to-4_20-GHz Intel® Core™ i7-8650U Processor (8M Cache, up to 4.20 GHz) Product Specifications
The Ark makes no mention of HDMI 2.0a.
So how does the NUC have HDMI 2.0a when the CPU itself only allows HDMI 1.4?
How is the HDMI output greater (60Hz) on the computer than HDMI on the CPU (24Hz)?
Does the NUC7i7DHNE output 4K at 60Hz or 24Hz? Have you merely modifed the DP
capacity of the CPU to go into the HDMI port?
Is the output of the HDMI 4K@60Hz?
Finally, if it is higher output, can it be back compatibility run by cable to an older monitor?
Have a look at this link, just to confuse the issue a bit more.

Hello, NCGuy. Thank you very much for taking the time to reach the Intel Communities Team. I will do my best to assist you further.
Allow me to perform a deeper research about this. I will be back to you soon.
Thank you very much for your patience, NCGuy.
Let me share with you that the Intel® Core™ i7-8650U indeed only supports HDMI* 1.4 will allow 4K @24Hz however, by using an LS-PCon converter chip, it is possible to support HDMI* 2.0/2.0a as a result, 4K @60Hz will be achieved. Please find this information on the processor's datasheet, page 34 of 214: https://www.intel.com/content/www/us/en/processors/core/7th-gen-core-family-mobile-u-y-processor-lin... https://www.intel.com/content/www/us/en/processors/core/7th-gen-core-family-mobile-u-y-processor-lin...
In this case, it is possible to reach 4K @60Hz and, have an HDMI* 2.0 port on the NUC7i7DNHE, thanks to the LS-Pcon chip on the board; which will allow additional features that are not included on the graphics embedded on the CPU.

How does the LS-PCon converter chip convert?
Is a full discrete 60 fps signal passed through, or is that that the 24 fps signal merely is adjusted so that the 24fps frames are spaced out over 2.5 60fps frames?
This might have an effect on simple video editing on Adobe Premeire Elements (the simpler editor)
I am sorry, I took so long to respond.
That is a really good question, NCGuy.
The LS-PCon chip will convert the signal from HDMI* 1.4 to DisplayPort*. The whole signal will work with the resolution and refresh rate that DisplayPort* allows to.
