Question: See my questions at bottom of post. First I’ll provide setup and background to these issues. Then this main question: Does anyone have clues or tricks on how to get hackintosh OSX (intel 4600 integrated graphics) to not only understand the resolutions desired in plist file but to make OSX **actually switch to using a true 4k at 60Hz?** I'm using displayport.
Hardware Setup: Gigabyte Z97 SOC, i7 4790k cpu, desktop integrated video (intel 4600 graphics, no vidcard), 8GB ram
Monitor is Wasabi Mango UHD420, HDMI2.0 pixel perfect, ebay from green-sum received last week. It came with a displayport cable and a hdmi cable, i might assume hdmi cable is 2.0 capable but that is *not* verified. i have no other hdmi or displayport cables.
OS: separate drive for each using a ssd/hdd switch box to connect or disconnect power to each drive in an isolated manner:
1. windows 8.1 64bit 320GB HDD
2. hackintosh OSX , 512GB SSD
3. ubuntu 15 live on dvd
-I collected EDID and other data from this in windows while getting successful 4k :
http://www.entechtaiwan.com/util/moninfo.shtm
Will include in the post for reference.
Notes and symptoms:
-#1 win8.1 with displayport does full 4k (3,840x2,160) 60Hz, 4:4:4. But on HDMI cable it only pulls 1920x1080 60Hz, drivers do not allow higher res than that.
-#2 OSX only will output 1920x1080 60Hz as of yet.
Creating/editing the plist files discussed on other threads (in this case one for when its over displayport and one for when it’s on HDMI) has allowed OSX to pick up those resolutions as options but when I choose them they don’t truly work - they are treated as scaled, so OSX just uses 1920x1080 to attempt to squeeze fonts and such to simulate a crappy version of 4k (I know I’ll probably have to swivel the monitor 180degrees to use OSX due to BGR) --> another but that's at least doable .
-#3 ubuntu shows full 4k with displayport! looks very nice. have not tried with HDMI, i think i will though. Edit - HDMI on my motherboard is 1.4a, not 2.0. So will be limited performance but would like to know how to get 4k at whatever lower refresh rate is possible such as 30Hz or 24Hz.
-Questions:
1. Is the OSX problem because I have unsupported cables either DP or hdmi? How to test if so , any way to test without just buying the nice cables (altho i will buy a couple to have longer ones at some point)? ***Edit -- cable works fine in windows and linux, its obviously supported.
2. Does anyone have clues or tricks on how to get OSX to not only understand the resolutions desired but to make OSX actually switch to the true 4k?
3. Any chance to damage the monitor by doing incorrect modelines or whatnot?
4. perhaps i should try to find modelines in ubuntu then use switchresx in osx to recreate those?
5. Any way to get OSX to support BGR as well as RGB pixels thus not having to swivel my monitor 180degrees mounting it upside-down?
6. And perhaps i will just have to buy a videocard to get this working? but i don't want to, waste of power.
Thanks for any help / advice.
