4k 60hz with HDMI 2.0 will work even on a Hackintosh using integrated graphics (iGPU)

So it's actually possible now to run a 4k TV at 60hz in HiDPI mode on a hackintosh over HDMI without an adapter and using only the integrated graphics, something that couldn't be possible in the past thanks to the inclusion of HDMI 2.0 on some motherboards. If you notice in the image above I'm running 4k60 over HDMI with Coffee Lake's UHD 630 iGPU on top of that I'm getting a nice 30-Bit Color Framebuffer Depth with HDMI 2.0 while Display Port can only max out @ 24-Bit Color, something that can be pretty useful if you work with Photos and Video on your hack.

I figured this out by chance while using my Gigabyte Z307N WiFi motherboard I happened to swap HDMI ports by chance as this motherboard comes with 2x HDMI and 1x DP and found that the HDMI portat the top supported 4k 60hz while the other one next to the display port below was stuck at the usual 4k24. This is because each port is running a different HDMI version with the upper 4k60 supported HDMI port being HDMI 2.0 and lower 4k24 HDMI port being the HDMI 1.4 supported.

I lucked out purchasing this motherboard over the many other motherboards because as turns out there are only three Z370 motherboards that offer onboard HDMI 2.0 while every single other motherboard only runs HDMI 1.X.

I can personally attest that the Gigabyte Z370N WiFi is a great motherboard. Quite a few people have had success with the ASROCK motherboard as well.I never tired hackintoshing an EVGA motherboard so I can't say how well that would work, but others have had success with them in the past.

The reason you would want to get a motherboard with HDMI 2.0 is if you are like me and have an ITX system you can actually run your 4k Monitor or TV at 60HZ without the need for a graphics card meaning you can use HTPC sized cases or simply not shell out more for an expensive graphics card. Your display needs to support HDMI 2.0 as a requirement however.

If you notice in the image at the top the HiDPI labels are missing but 1920x1080 is running at 3840x2160 while the 1080p option is just 1920x1080. You would select 1920x1080 if you wanted Retina resolution. Also if you plan to use the 4k display in HiDPI mode you will need to disable animation/transparency until full native support comes to avoid graphical glitches associated with using scaled resolutions see: https://hackintosher.com/guides/fix-coffee-lake-uhd-630-igpu-from-glitching-hackintosh/

Hey, just to clarify the iGPU part. Intel's official spec for UHD-630 only support HDMI 4k output @ 24hz.
Motherboards that support HDMI 2.0 are using a DP to HDMI converter chip.
The Gigabyte ITX boards both Z370N WIFI and H370N WIFI, support 4K@60Hz through the top HDMI 2.0 port by having a Megachip MCDP2800.
Not sure about the color depth capability of UHD630 tho.
