Just awful

I was an early buyer of the LG UltraFine 5K, and I'm amazed at how little LG has done since the release. I guess we now know why Apple is back to making their old displays.

First, LG has gutted this app. It used to have a feature to divy up windows across your screen. It wasn't perfect, but it could save time in certain situations. Well, that's gone now.

Numerous features that were originally advertised never came to fruition. The ambient light sensor was never turned on, for instance.

Finally, this app just doesn't DO anything. No customization, no color control, no sound control. Nothing. I don't know why it exists. You can't even turn the sound up above 3 notches, or else it will blow you you.

Pass on this app. Better yet, just pass on LG. I just returned another monitor from them (the 49" 5K) because it didn't work. Period. Never worked. It took 10 hours of support calls between Apple and LG before an LG tech finally admitted that it was a known fault, and they intended to patch it "hopefully within a month." That sucker got packed up and shipped back.

Don't count on LG to support their products.

...IF YOU HAVE AN APPLE SILICON COMPUTER (M1). The Screen Manager App will install via Rosetta but will NOT work and will not recognize the display and wont allow you to determine the firmware or update it. LG does not make a firmware update available through their support webiste only via this app THAT DOES NOT WORK ON ANY M1 chip computers. Also - the vast majority of users with an Apple Silicon computer and the LG 5K or 4K montior experience pixels distortions that appear randmoly and require you to unplug and replug your thungerbolt or USB C connections. Rather odd....I mean these two displays are the ONY 3rd party displays Apple sells directly and recommends on their website. One would think they would put some pressure on LG......

I got LG Screen Manager to work under Catalina.

I just got a "new" (to me) LG 22MD4KA-B monitor to go with my 15" MacBook Pro. It's running Catalina. At first LG Screen Manager saw that my monitos needed an update, would download it, but the monitor would crash when the software was installing.

So I hit the Google. After mucking around, I only did two things that might have solved it.

I quit LG Screen Manager. Opened System Preferences, hit the lock icon and entered my admin password. Then I launched LG Screen Manager. I clicked "Update Monitor" and then sent the app to the background while I was browsing the web. It slowly updated the monitor, and now my monitor is running software version 3.11,3.4, 5225,3.04,0.2f. (That's literaally what it says in the update screen.) So, there's hope? Try that?

I think LG Screen Manager is failing to ask for somer permission it needs. I would have given it one star, but it got an extra since I did manage to get it to work.

LG: Please fix this app.
