Just like the days of 60Hz are over, so are the days of gaming monitors being rather useless for work and productivity. If you choose the right display, you get an all in one package that offers superb gaming performance without pushing out other applications.
So yes, gaming monitors are good for general purpose work from home type scenarios. Emails, documents, basic graphics work, video conferencing, and many other kinds of productivity all benefit from the higher specs offered by gaming monitors compared to basic office displays. For example, video calls take advantage of the excellent audio and smooth refresh of good gaming monitors. And extended work sessions are easier on your eyes if the monitor has been designed for lengthy gaming marathons, because eye fatigue principles are nearly the same in both.
Of course, if you do photography, video editing, or design for a living you should get a monitor specifically made for color-accurate work. Gaming monitors will not suffice here, as they are not as well calibrated and are designed with game visuals in mind. Also, photographers and designers don’t benefit from high refresh rates and low response, and may actually prefer a 60Hz panel since those are closer to “real life” than the hyper-fast panels popular in gaming.
People that should look at good gaming monitors are streamers and influencers. First of all, if you upload videos regularly, you want good color performance, and gaming monitors of the class we have in mind deliver more than enough for your needs. Also, if you stream gaming content then you don’t need multiple displays cluttering your desktop. One top-tier gaming monitor is all you need.
