Only in certain circumstances.
For instance, my Samsung secondary is 23" and 2048x1152 but it's not much better than 1080p where visual quality is concerned and my NEC beats it hands down in the color department. It also got discontinued rather quickly.
There are several expensive 27" LCDs that are 2560x1400 but those haven't been very popular because of price. 30" LCDs from Dell, HP, and NEC have a res of 2560x1600 but they are all usually over a grand. For another grand you can have a 31" Asus 4k screen when it comes out which makes more sense in my eyes. You also have Apple Retina displays and I haven't even looked to see what those cost. In most all cases, the standard res is 1080p for 22 and above.
I actually know some people that use 1080p large TVs for PC monitors and I don't see how they do it. Would drive my eyes insane with both the closeness of the large screen and the fuzzy text.
