1920 widescreens are not really wide enough for a webpage and a code window. A 2560 widescreen is the obvious answer but they cost 3 to 4 times as much.

You're right. I guess your other suggestion was really still making a "wide screen" but a super high res one out of two squarer ones :-) That seems a reasonable solution.

I have 2560 pixels wide but I have a 27" iMac and sorta consider the screen almost a "freebie" with the computer (considering how little extra the 27" costs). A similar stand alone screen is crazy money though..

Simple solution: buy two monitors. Only costs twice as much.
