New 2023 MacBook Pro 16 M2

OnSscreen Control 5.57 does install but will not detect the High Class 5K LG UltraFine 27MD5KL Monitor.

This Monitor has no switches, keys or buttons to control settings (Luminance, Contrast, colors, etc, etc) and only one input for Thunderbolt 3, so i have no control of the Monitor except Brightness via the Ventura Display Settings window.
Maybe only a problem with my particular Monitor, but still then very annoying!

Installed OnScreen Control version 5.57 today on a 2019 MacBook Pro running Monterey 12.6.1 with an Intel Core i7 processor. And after starting up OSC I initially see all 4 setting options, but after less than 5 seconds 3 of them disappear and all I am left with is "Screen Split."

I talked with LG Support for about 30 minutes and their only solution was to try attempting a direct HDMI to HDMI or DVI to DVI connection. The only 2 types of connections available on my LG monitor are HDMI and DisplayPort. Neither of which is directly available on my MacBook (4 USB-C slots).

I have been researching this issue a lot today, and I have come across numerous comments on different sites and forums all highlighting the same shortcomings with OnScreen Control and MacBooks.

I have a 34" Ultrawide LG monitor that cost me $500 and all LG is telling me that I can do with its own features is "Screen Split." Which is the opposite of what I have been reading about Windows users. Nobody running Windows seems to have this same issue with OSC.

After last update to 5.57 not working properly with MacBook Pro (201Dirol OS Monterey 12.6

Two computers attached to this LG HDR WFHD Display (with HDMI ports).
During switching between HDMI1 (Mac) and HDMI2 (HP) connection with HDMI1 (Mac) became to be lost.
Go back to HDMI2 (HP) all connection exists.
To have LG monitor work as an extended monitor for Mac - HDMI cable have to be disconnected from Mac and connected back again.
If I will switch to HP and after that return back to Mac connection are loosing again and action "disconnect/connect" have to be repeated.
Please suggest.
