4K With Skylake - Possible Without Graphics Card?

[melodasi]

Yes, you can get 4K resolution with the Intel HD 530 Graphics that are included with most Skylake processors. Just remember that you need either HDMI 2.0 (still rare) or DisplayPort to get 4K at 60Hz. (Bottom line: make sure your motherboard and 4K monitor have DisplayPort, and make sure your DisplayPort cable is good quality and certified.) Also, make sure your 4K monitor can run at 60Hz and is a single LCD panel; some of the cheaper ones use two individual 1080p panels side-by-side and/or display 4K only at 30Hz.

Oh, the statement "...Haswell architecture, which was capable of supporting just one 4K monitor at a mere 30Hz" simply isn't true; I'm typing this now on a Haswell i5-based Hackintosh with HD 4600 Graphics running at 4K @ 60Hz (over DisplayPort).

I have a Samsung U28D590 connect to the HDMI Port of my Asus H170 with 4K resolution, but the when loading it flicks alot and also, it seems not be be accelerated.
My injection configuration for Intel is true, but I have no ID (if I add the id I get black screen).
Any ideas?

It's fortunate I am a bachelor. It has been at least a month of constant ranting with me. It was driving me so nuts I just couldn't sleep last night. I spent part of the night trying to make the darn thing work. I eventually succeeded but I am absolutely worn out and I can't even enjoy using it [because I am] so POed .... about the time and energy I wasted on it. The sucker is sitting by my desk and I am still using my Mini. On one hand I would say “never again“ but on the other I am now seasoned and would probably succeed with the next one more easily.

You have the makings of being a tech... You did good. Don't blame the new PC - it's just a matter of trust - you don't trust it because you may want to play with it until it breaks. That is very human. It's hard to know when to quit tweaking. If you don't munge it then you will slowly start transferring data over to it. After awhile you'll be using it all the time. But you may never trust it because it breaks when Apple does an update or you will laugh because you now have the confidence to easily fix it.

Just keep doing your backups. Just in case.

The thing has been working without a glitch for about two months so far. The only little issue is that it restarts after shutting down. So far I didn't try the Wake up on LAN setting in the UEFI. Actually I shut it down very seldom and I switch off the power when it finishes the process.
All this is behind me now and I am torn between two attitudes: a) "Never again". It was a nightmare that ate up my time and my nerves. b) OTOH, now that I am experienced next time it will be a breeze (hopefully).
As a matter of fact it was a long term investment. My needs are limited (I am doing photos, no games an no videos) so the configuration I chose should be up to the task for many years. I basically needed a faster CPU than my Mini's with at least twice the RAM than its 16 GB max.
I plan in a foreseeable future to increase the RAM to 64 GB if necessary and maybe add an SSD too. In a more distant future I may upgrade the CPU. But I don't think I'll build a new one before long.

Just keep doing your backups. Just in case.

Well, that's routine.

Really, I don't get it ...

View attachment 201997

... i clearly states "Max DP Resolution ≈ 4096x2304@60Hz" ... what else do you wanna know?

Obviously you cannot rely on this information. I have an i7-4770s which, according to ark.intel.com should give me 3840x2160@60Hz over DP. My mainboard is an ASUS Z97-A which also allows 3840x2160@60Hz over DP. Yet all i get is 2560x1440@60 Hz.
I had to by an external GTX750 to get 4k@60Hz.

Since i am going to start a new build, i would really like to know if 4k@60Hz will work more reliably with new CPU's (Broadwell, Skylake)

Is there any news on this? I'm planning to get the following hardware:

• Streacom F1C-WS
• LG 34UM88C - a nice Ultrawidescreen QHD Monitor.
  
  So the question is, will the integrated Intel HD 530 run the resolution 3440 x 1440 at 60hz? If yes, which output do I have to use?
  
  The Intel site says it will only run it on eDP, which means I would have to use an extra internal PCIe Displayport card, right? But would that be even supported by mac drivers?
  
  Thanks for your help in advance, I just don't want to buy the wrong stuff.

  Your chosen board has 2 x HDMI 1.4 but no DisplayPort.
  
  According to the HDMI 1.4 spec, 3840x2160 only goes up to 30Hz, while 4096x2160 only goes up to 24Hz.
  
  Nice CPU cooler choice btw

Thanks for your quick answer. I took the mobo, since it was highly recommended for compability issues. Can you recommend any other mainboard for my use or do I have to use an external graphics card?

 

[WonkeyDonkey]

External graphics in the way you are thinking about them would not work. I believe you need Thunderbolt for that. The eDP you refer to from Intel's website is for Embedded DisplayPort (Not external) and is normally used in laptops.

Your best bet would be to find a board that has DisplayPort output, which will give you the full 4K resolution and 60Hz refresh rate.

The motherboard section of the Buyers Guide shows the current recommended ones and includes the display options for each. Use that as a starting point, then have a search of the User Builds section of the forum to find out which itx boards people are using and what issues, if any, they are having.

 

[litchblade]

Thanks! Will do so

Like I did It was $160 mistake.
OS X doesn't deliver the resolution you want through HDMI but only through DisplayPort, period.
AFAIK very few mobos have a DP. That's the thing you must check.
