Mac Mini 2014 4k display 60Hz max resolution

Hello,

I can read in the infos for the new iMac 2014 that is possible to use 2 x 27" Apple Displays over thunderbolt.

My question is, what is the max resolution what you can use with one Display.

Is it possible to use a Mac Mini with a LG 34UC97 with a resolution 3.440 x 1.440 60Hz with thunderbolt.

The HDMI supports only 30 Hz.

Thx

The HDMI interface as you said only supports a max of 30fps and not 60fps.

As far as I can tell the Mac mini via Mini Displayport does not support - at least officially anything above 30fps for 4K displays either. This is because the Mac mini does not (again officially) support Displayport MST functionality. MST = Multi Stream Transport. See Using 4K displays and Ultra HD TVs with Mac computers

The same article above does imply that the Mac mini can support a 4K display via Thunderbolt/Mini Displayport but makes it clear that it can only do 30fps because it does not support MST.

you can be right, not officially, but for now:

"On a late 2013 13" MBP/Retina, using SwitchResX, I was able to get the ASUS PB287Q to drive 4K (1920x1060 pixel-doubled "HiDPI") at 45Hz, rather than the max 30Hz offered through the standard Display Prefs pane.

Here's how: I created a custom resolution by copying the 1920x1060 HiDPI 30Hz, and then set its vertical sync to 45Hz (and rebooted as required by SwitchResX). The 45Hz refresh rate is now available in the Display Prefs control panel, and the ASUS OSD confirms we are operating at 45Hz.

Before getting 45 to work, I also tried 50 - but even after reboot it was marked as "invalid" so I suppose I'm maxed out.

45Hz isn't 60, but it is much better than 30."

ps: i don't know how to de-highlight text, sorry, just cmd-v&cmd-c.

I haven't been able to find reliable information about the compatibility of the LG 34UC97 (incurved 34" display with 3440 x 1440 pixels) with a Mac Mini (Late 2014) when the display is plugged via Thunderbolt 2. Apple's info says that Thunderbolt 2 can power 2 Thunderbolt displays (2560x1600) but only mentions the LG's resolution as being driven via the HDMI port at 30Hz. So what happens if the Thunderbolt 2 plugs into the LG's Thunderbolt 2 input?

For clarity. That TV does NOT have Thunderbolt input. The Apple Thunderbolt display is the only monitor that actually uses Thunderbolt. Other monitors use a mini displayport or display port. A mini displayport plug plugs into a Thunderbolt port for video.

no, this lg display does actually have thunderbolt v2, when connected it drives usb ports on my display

Wow. Like Illaass I thought the situation was that while many manufacturers made Displayport compatible monitors only Apple had made a Thunderbolt compatible monitor, I therefore had to double-check your claim. You are of course correct based on their webpage. They are not however themselves using any of the extra functionality possible via Thunderbolt, for example while the monitor has some USB ports these are not provided over Thunderbolt meaning you also need to run a separate USB cable from the Mac to the monitor. (It also does not have Ethernet built-in.) The fact they are not themselves utilising the extra capabilities of Thunderbolt means either they are simply doing Thunderbolt daisy-chaining or like many people they have got confused between ThunderBolt and Mini Displayport. If they only do Thunderbolt daisy-chaining this is still a significant benefit as you can then plug other Thunderbolt devices in to it which you cannot do if the monitor only does Displayport.

For the benefit of others a Thunderbolt interface supports both Thunderbolt monitors and Displayport monitors but they are not the something. Thunderbolt is a mix of Displayport and PCIe signals so it can do everything Displayport can and also support additional functions via the PCIe signalling.

PS. I found that the URL one had to visit is http://www.lg.com/monitors/lg-34UC97

Hey John Lockwood,

i have this LG model (34UC97) which i purchased 3 months ago, what you are saying is not true.. basically when you connect the mac mini via thunderbolt you also get usb over thunderbolt on the back of the monitor, and you can also connect a thunderbolt ethernet on the second thunderbolt port which means you can get USB + Ethernet..

also this monitor is KVM capable, which means you can switch between a mac mini and a pc with one keyboard and mouse..

and Yes, if you connect a mac mini 2014 you will get 3440x1440@60Hz (only over thunderbolt)

here is a video showing LG KVM capability >> https://www.youtube.com/watch?v=BFkY3V6Te2A
