Hey there - I just bought the LG 31 MU97 4K Display and the best resolution I can get out of it is 3840 x 2160. Wondering if there needs to be a service update of something similar in order to get the full 4K on the new 2013 MacPro - thanks.
Mac Pro (Late 2013), OS X Mavericks (10.9.1), 6 Core
So I have a 2012 macbook pro. I can't for the life of me get it to run at 4096 with the display port. It only shows 3840 as max even after holding the alt/option key and clicking on the scale. I can however use HDMI and get the full resolution. Albeit at a much lower refresh rate than I would like.
It does work for me though because I use the larger monitor as a second screen to display ARGB images from my mac pro.
Not ideal but for now I'm happy enough. Wonder why the difference between hdmi and displayport?
Does Anyone know if this monitor supports dual Display port functionality? Can I plug my mac pro in the mini display port input, and a gaming PC in the display port and toggle between them, or does only one "display port" work?
Most TV sets and Monitors have multiple inputs so that you can plug different sources into different ports on the display.
When one is a Mac, you need to be sure the display is "paying attention" to the port you want the Mac to use when the Mac is powered up, or the display may stay blank.
One model of ultra-wide LG display requires you to plug in both BOTH display ports -- one for each side of the screen (behaves like a 5K display) -- and not doing so gives no picture.
So isn't toggling to the "mini Display port" on the monitor settings make the monitor pay attention to the port?
Right now, I am using a Samsung monitor, and its driving me crazy. When the mac goes to sleep, it awakes to a blank screen (monitor powers up) but no image. My only way around it is to unplug the mini display wire from the back of the mac pro and plug it into another port -- doing so "usually" restores the picture.
Many TV sets try to switch automatically, but at the moment it appears the ones that switch do not switch fast enough to hear the Mac's query for their name and capabilities, and end up staying dark.
Yes this wouldn't be automatic, i would manually switch. I just wanted to make sure only one display port can be used, and that i can use both the mini and the regular ones and each has a input mode on the monitor software
"The old way" was the TV set had ONE input, and you needed a 'Video/Audio Amplifier and Switch' device to select your inputs.
When HD TV sets required re-tooling anyway, they decide to provide multiple inputs on the TV sets and Monitors. Now they all seem to have that feature.
I had problems with this monitor and a MacPro late 2013 to show 4096x2160 at 60hz connected by daisy chain through a Hard Drive with thunderbolt port.
While I used it by daisy chain, the monitor has problems and I need to setup to show 4096x2160 ONLY at 50hz PAL. But sometimes it lost signal.
After I reconnect this monitor directly to thunderbolt on MacPro, and now it works perfect 4096x2160 at 60hz.
I post this information if anybody has same issues like me. Regards.
