Ah, so you guys are saying that (for example) in bfbc2 when the resolution is set to 2560x1600, that I still see the same amount of information/fov that I do currently on my 1920x1200?
I was under the impression that it more or less kept everything the same size (as on the 24 inch) but the added pixel resolution DID show more information/fov.
So 2560x1600 30" monitor without AA is sort of the same thing as outputting to a 30" 1080p lcd tv with 2x or 4x AA? In other words, the graphics quality/horsepower goes up, but no new information is displayed.
Thanks for the input so far guys.
Let's say you're looking at a stadium of 10,000 people. You were some horse blinds and you can see 4,000 people currently. Going 3x1920x1200 is like removing the horse blinds allowing you to see more people (lets say 7,000 people instead). On the other hand going 1920x1200->2560x1600 is a lot like putting on better glasses, you can see people further away more clearly (you would still see 4,000 people). However since you have increased DPI, if your doing something where pixels matter e.g. pixel hunting in a game with pixel-perfect aim then it is helpful.
For example in Red Orchestra 2 you can snipe with any rifle's iron sights or Counter-strike with desert eagle, you pretty much get perfect aim across the map and with a bigger monitor you can snipe
without zooming in more easily.
Also in an RTS or RPG with unlimited zoom you could zoom out more without having units become total pixels (e.g. Total War series, most other games will lock camera not to give an unfair advantage).
