You're right in that there are plenty of different options out there for monitors. The 3d-monitor option you've been looking at thus far probably isn't what most people would go for in your situation, but it's not as if it's a poor decision; you just need to understand the limitations of 3d-gaming using a laptop and HDMI (which you do).
If you decide to head down the 27" 1080p pathway, there's a metric tonne of options out there. I haven't heard much about that ViewSonic panel here on OCN , so while it probably isn't the worst choice you can make, it also probably isn't your best choice either.
The vast majority of members here on OCN will stand by offerings by Qnix, Asus and BenQ for all monitor types; be it 24' to 27' in size, 1080p to 1600p in resolution, 60hz to 144hz in refresh ratings, as well as TN or IPS style panels.
Going back to your original post, I'd say your best bet for an all-round awesome monitor experience is probably going to be a Qnix QX2720
or a Qnix QX2730
. The 1440p variants of these monitors are owned by quite a few OCN members
for use in single- or triple-monitor setups and feature really high quality panels with really great colour replication. They also can be overclocked beyond the default refresh rate up to and beyond 120hz in some instances (no guarantees, it's a lottery). To use one of these, you'll have to also pickup a HDMI to DVI-D adapter, since there's no HDMI socket on the Qnix monitors. As you probably know, DVI-D is exactly the same as HDMI except without transmitting sound to any speakers built in to the monitor.
As mentioned by StatikGP, the VG278HE is also a great option. Along with the points he mentioned, it will give you much the same experience as a Qnix monitor except you trade faster response time (2ms vs 6ms) for slightly poorer colour replication (TN panel vs IPS panel).
