Chrome 87 on Windows and 1536x824 screen resolution? Please stand by while I fire up a Windows 10 VM and emulate that screen resolution so I can get banned for being an "alt account" of webtricks /s
The thing is... the resolution is a lot more common than it seems - it's a 125% scale of 1080p, not an unusual thing to do on e.g. a laptop. The user agent is obviously vanilla latest version of Chrome on Windows 10.
