My LG DualUp monitors (with no internet access) recently triggered some LG Adware Bullshit to install on my Windows laptop. So I'd say stop using LG anything (or Windows anything since they're voluntarily in on the scam too lol). If you want the 2560x2880, maybe buy the knock-off INNOCN vertical monitors.
