I'm curious: what are the "lot of" modern games "that have this problem"? Can you come up with ten names of major 2012 releases? Can you come up with even five?

Massive list of games that don't support Horz+ correctly, there's even more on the forums this is just a list of games with reports, the forums list way more.

Running 1080p on a 1200p display or 1440p on a 1600p display is waste; there's nothing subjective about that. If you run in the lower res 90% of the time, then those extra pixels are 90% wasted.
It's not a waste if you specifically want 1080p for gaming, if for whatever reason you absolutely must have it, yet want to work on a traditional PC monitor which was designed with a 16:10 screen that is useful for the millions of other applications that PCs have.
You pay about 50% more for 11% more pixels, which will furthermore only be a benefit in maybe 10% of new game releases (and that is a wildly optimistic estimate). If money is no object, and you don't care about black bars, then sure, get 1600p. But 1200p screens are pretty much never a rational choice for gaming, and rarely for anything else either.
That's because most 1080p screens a crap panels, and most of the remaining 1920x1200 screens are actually pretty decent IPS panels, I'm not going to go into pros and cons of each, suffice to say that there's a reason some panels are more expensive, it's because in a free market you get what you pay for, and the reason 1080p are the most popular panel type is because that's the cheapest way to achieve "HD", TN are also the most popular panel type and demonstrably the worst for a lot of things.
Kinda like arguing that McDonalds is cheaper than a 5 star restaurant, it might be right but it's a stupid argument. Yes they're cheaper, they're cheap pieces of crap
You've limited your scope to ONLY GAMES, and ONLY GAMES IN 2012 and completely ignored not only all the other games out there that people play but also the multitude of other things people do with their PC.
1080p is just a fad it's the new kid on the block that happens to be cheap so it sold well in the PC space due to sheeple buying up anything cheap (kinda like TN panels), meanwhile 16:10 was the already well established aspect ratio for many years and all widescreen gaming started out on 16:10 panels. Been around long enough to know that fads never bring much to the table, original standards are used for a good reason
