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.

I would probably have a DualUp by now if I could find one available anywhere: it's a very appealing form factor. I looked at the INNOCN site, but only see normal-looking monitors there; do you have a model name or any pointers I could search for?
