What do you lose with 16:9 monitors?
A huge part - about 12% of vertical resolution (considering interfaces) for general use is lost.
Remember that it's the vertical resolution that defines the rank of the panel (in terms of size).
And all of 16:9 "HDs" so far are ... TNs - the bottom level of LCD technology!

Let's dim these marketing bells and put a big cross on those half-finished "Full HD" TNs, because HD means High Quality first of all.

Now back to REAL HD monitors.

The 2490 has several features that work well for advanced video support.

Two digital inputs and D-Sub for multiple video signals.
Supports progressive signal up to 1080p without overscan.
Supports 1080p/24p incoming signal (displayed as 1080p/60) and everything between 24-60Hz.
Viewing angles same as plasma TV due to A-TW polarizer.
Internal LUT calibration valid for standalone devices (BD-players, PS3, etc.)
Separate calibrations can be performed (for each input).
Unlimited scaling. Black bars can be adjusted or removed. Any frame format can be adjusted to fit the screen. Wrong format video (incorrect aspect ratio) can be corrected.
