What size and type of monitor would be suitable for a architects computer?
I would have to say for architecture, the answer is “the biggest monitor you can afford.” There are only a few professions where screen real estate is an absolute must, and this is one of them. I would also strongly suggest considering multiple monitors with something like a pair of 24″ monitors (1920×1200 resolution) or one 24″ to 30″ monitor as a primary display and a smaller 19-22″ monitor as a secondary display. (The secondary display could always be added later.) The primary is used to display the work at hand and the secondary display is for things like toolbars (a la Adobe Photoshop, Illustrator), email, word procssing, web browsers, etc. That way the work can be kept at the front while reading whatever specifications are pertinent or viewing site photos on the other. Almost any computer purchased today will support dual monitors – and the one needed for this type of work is more or less guaranteed to. You didn’t ask about the computer itself, so feel free to skip over this part
