I beg to differ... a high resolution monitor might be viewed as multiple monitors combined.
No. Sorry, but that is wrong. I don't understand why are you trying to make this argument when you have admitted yourself your lack of understanding of the advantages of dual monitors? That makes no sense.
One large monitor does NOT equal two smaller monitors - regardless the resolutions. If you think it does,
you don't get it!
And I will say it again - the resolution has nothing to do with this. If you think it does,
you don't get it!
If anyone is thinking of buying a new monitor for a single monitor setup, my advice is to get the best monitor their budget will allow.
If anyone is thinking about moving to a multiple monitor setup, my advice is to the best monitors their budget will allow.
The only added advice for a multimonitor setup I would add is try to find monitors that have very thin bezels. That said, even if the bezels are wide, our minds are wonderous things and before long, those bezels and that gap disappears - much like the rear view mirror in our cars. Its still there, we know, we just don't see it until we consciously look it.
I'm sort of with Andy on this.
I had dual monitors for a long time, but once I started working on a 55" 4K screen,
Now wait a minute! A 55" big screen TV (even if used as a "monitor" can hardly be compared to a dual-monitor setup. Surely you are not sitting arm's length away from that screen, for example.
And Andy is suggesting resolution is the determining factor. It is not. It may factor in, but it is not a primary factor. Super high resolutions are great for image viewing, but not so much for text, for example. You still have to be able to read your Word documents, spreadsheets and forum posts.
If you are playing a game and sitting 6 feet away or even across the room, then sure, a big screen hi-rez TV may be ideal. But if you are doing work, sitting at a desk, with your monitors sitting on that desk, and have many open windows, a dual monitor setup is a great solution.
