In my home office I run dual Dell 22" monitors (1680 x 1050 at 16:10), that are a number of years old, and thinking of upgrading.

My work ranges from coding/development (c#,databases/php/js/html/css etc), solution architect documents, server management (SSH), remote desktop access, etc.
And no gaming.

Is it worth me upgrading to dual 24" 1080p monitors, OR would going from 1050 to 1080p not be noticeable?
Apart from a slightly wider screen and a few more pixels? (24" 1080p screen looks to be same viewable screen height, but wider screen that my current 22" 1050).
As going from 16:10, to 16:9

Or should I go to dual 27" 1080p? Or would that start to put a strain on my eyes? Where does increasing the size of 1080p monitor become redundant unless going 1440p?

Otherwise I could wait a bit longer for 1440p monitors to come down in price.

Interested to hear what size/resolution dual monitors others run, either at their work desk, or home office desk.

Thanks
