Need a lesson on todays monitors

My budget has increased, so what the heck... What monitor specs should I be looking for. On newegg under Monitors it lists "Large Format Display" and "LCD Monitors"... What's the diff?
So far the only thing I "think" I know is I want a large contrast, low pixel change time and small DPI. That's about it.
Can someone provide a quick lesson as to what to look for? In the old days it was a large resolution, small DPI, fast refresh and minimal difference between "monitor size" and "viewable area".
My real desktop (with a hutch) can hold 23" high x 40" wide. So my trig calcs say it can be about a 46" monitor without the stand.
Any and all advice is welcome and greatly appreciated.
Thanks for your time,
Joe
EDIT:
After my initial search based solely on dimensions, price and resolution I've found this...
