Curious to know how this works with ad-heavy sites. Do responsive sites display differently then too?
Been flirting with going to a single 32" monitor for a while. Just wondering if you think it's worth it with your experiences since I do development as well and have a similar setup (one monitor for editor and smaller laptop for browser/terminal) and would like to hear your input.
But, generally, it's fine. Most sites are entirely usable. There's a few that are quirky, but generally, modern websites are designed to scale down to tablets and phones, so they don't act too weird for a narrow lapptop/desktop browser.
I think the most common problem is sites that switch to hamburger menus at too high a resolution (so I get the mobile hamburger navigation on some sites, even though it's kinda silly looking and slightly less ergonomic). It's not super common, though. Most switch to hamburger a little lower than my browser width.
Monitors might be wider, but screens in general are much narrower.
