Why the U2211-H panel?

Why did I get this relatively small 21.5 inch panel (note that I paid 219$ CAD not the 319 it is normally) instead of, say this much larger, comparably priced panel.

Doesn't go into portrait mode.. Doesn't have a display port.. is too big 4 me (24 inches yipes! 3 of those won't fit on my desk) and it's a TN panel..


"TN (Twisted Nematic) panels are the most widely used panel type in the manufacture of LCD monitors. TN panels are cheap and offer excellent response times, making them perfect for fast paced gaming. The response times of current TN panels range from 2ms to 5ms. However, color reproduction, viewing angles and contrast ratios of TN panels are the worst of any current LCD panel technology. Unlike most 8-bit IPS/VA based panels, TN is only 6-bit and unable to display the full 16.7 million colors available in 24-bit true color. They can mimick the 16.7 million colors of 8-bit panels using a technique called dithering, but the results are unimpressive. TN panels have become popular with the average computer user because they are very inexpensive and currently dominate the LCD display market in availability."

The "ultra" panels from Dell are the latest generation of ISP panels:

"S-IPS/H-IPS (In Plane Switching) panels are generally considered the best overall LCD technology for image quality, color accuracy and viewing angles, but this comes at a price. They are well suited for graphics design and other applications which require accurate and consistent color reproduction. S-IPS panels offer the best viewing angles of any current LCD technology, with wide viewing angles up to 178 degress. The response time of S-IPS is adequate, ranging from 6ms to 16ms with current panels. This is only slightly slower than TN panels. However, gamers should take this into consideration. Fast paced games may suffer from motion blur or ghosting with S-IPS panels that have a response time higher than 8ms."

Wikipedia also has a good article on the topic of panel types:
