LG True Color Pro 31MU97

Hi!

I've just buy a 4K monitor LG 31MU97 and connect it to my MacPro 2013 (6core-D500-MacOS 10.12.6)

The monitor works fine but when i install the software True Color Pro 3.7.6 (last version on LG site) the application hang... The monitor is connected with original mDP-DP cable and original USB 3.0 cable, i can see the icon app on the top bar but the app won't start.. sometimes it's closed after 20 seconds, sometims remain here for more time....

Without this app i can calibrate the monitor!! :-(

Anyone have this issue? The LG support is very bad....

Yesterday i also reinstall the MacOS and after the i just install the Tru Color Pro app with the same results...

Moreover i also install x-rite i1 Display Pro software with the LG True Color Pro (in order to have correct drivers?), but x-rite software works fine but i can't calibrate correctly the monitor... and the LG sowftware is always hang...

Can you help me?

Thanks

Mac Pro, macOS Sierra (10.12.6), 2013

Hi there,

Just noticed True Colour 3.8.3 is available for download. Maybe that'll help.

As in lg-31MU97-B ?

And your using LG Mac_TCP_3.7.6?

What version of macOS are you using?

Have you tried disabling SIP and then installing true color?

Have you tried contacting LG support?

FYI LG calibrates the monitors are calibrated at the factory.

Strange, I was able to calibrate my monitor when I first got it. Since then, I have reset all the settings, and lost my calibration. When I first got it, I had borrowed a calibrator from a friend. That shouldn't make a difference. I now have my own, and I can't get the dumb True Color Pro to work. I was an idiot and installed the latest version, as my old version launched, but didn't see my calibrator, so I updated... big mistake.

I even tried it with window 10, and I tried it on my Macbook. The windows version crashes & hangs the same way....

If you're still looking I have 3.6.3 available. Still no update from LG and it freezes on High Sierra! LG should close up shop in 2018. Their support is for the gutters!!...

Thanks TeetTitan

My monitor is LG 31MU97 , i think is one of the first models without thunderbolt....

Yes i use the 3.7.6 version with macOS 10.12.6

The LG support service says that the sofware is good and the problem is of my mac.... :-(

The only thing that i don't tray anymore is disabling the SIP...

but i also try the TCP 3.7.6 on my mac mini server via VNC and without disable SIP and the software start normally....

I would like to help you but there is no help for this display. After two years of fighting it I finally tossed this $1100.00 display in the trash pickup. It looks great but functions below par. Its now out of sight and out of mind. I would not sell it to an unsuspecting person.

I wish LG would post their older software versions!!!! I scoured the internet ant found v3.5.0 that loads, sees my Colormunki Display as an i1Display Pro. Allows me to set profiles as targets. Then it displays the graphic to flip the cover to expose the lens. Then it says there was a communication error with the calibrator.

I so wish I could find v3.6.3. If only someone still has TrueColorProV3.6.3.pkg....

If LG would come out with a version that works!
