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.

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.

Crashes immediately everytime

I cannot even get the app to stay open long enough to check for a newer firmware version. It loads in the menu bar for about 5-10 seconds and disappears with no error message or anything. Tried uninstalling and reinstalling to no avail.

PLEASE UPDATE YOUR APP AND PROVIDE MORE FEATURES THAN JUST FIRMWARE UPDATES (even some of those would be nice considering all the trouble I've had with this monitor). Going months without an update to your only software package related to your extremely overpriced monitor is insulting to those that paid the extra money for a "premium" product.
