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,
How does this LS-PCon converter work?
Does it up the data stream?
Or does it merely take 1 frame from the 24 fps, and extend it over 2.5 frames on the 60fps? To put it simply are we getting a true 60fps, or merely a modified 24fps spread over 60 fps?
How does one get an 4-lane eDP 1.4 out of the NUC7i7DHNE without there being display ports on the mobo?
Or am I reading this wrong and all we are talking about is data rates?
Could I use a USB 3.0 to DP adapter?
The reason this is being asked is that I am considering a NUC7i7DHNE to do small 10 minute video with Adobe Premiere Elements. Nothing really heavy.
When configured for HDMI output, it is true that the processor can only deliver support for HDMI 1.4. When configured for DP output, however, the processor delivers support for DP 1.2, which far exceeds the capabilities of HDMI 1.4. As noted in the processor's datasheet, "HDMI 2.0/2.0a support is possible using LS-Pcon converter chip connected to the DP Port. The LS-Pcon IC supports two modes, (1) Level Shifter for HDMI 1.4 resolutions or (2) DP-to-HDMI 2.0 protocol converter for HDMI 2.0 resolutions."
Summarizing, two DP 1.2 streams from the processor are converted to HDMI 2.0/2.0a streams using LS-Pcon chips.
If you want to connect a DP monitor, you have three options:
Hope this helps,
