I own an Acer AL2216WBD. Cheap budget TN panel.
The thing is I expected a cheap panel, some light bleed, several off colors, uneven backlighting, black sucks, etc, etc.
During black scenes when the light's off you can REALLY tell the uneven backlighting (more light in the center). When looking at websites with solid colors (like orange) the orange will seem darker in other areas. Backlight bleed is not really that bad unless you're staring at complete black (e.g. Pan's Labyrinth or other movies/games). Black isn't black, however you can really only tell if you're comparing it to another black object then it will seem a bit light (don't worry it's not gray) just a very very light black.
The good parts:
-Cheap
-Works well for just everyday tasks, some gaming here and there, browsing, etc.
-It's big, I like the pixels and the additional VGA (hooking up an ATSC/NTSC/QAM tuner)
Well I don't do work where the right color is crucial, but if you're really sensitive to something that isn't perfect when it comes to color, or if you need to edit images/movies then get a better panel like the Samsung or a CRT. However, this panel is made to be low-quality, hence "budget monitor" but it serves me well and I like it. Despite the 2 dead pixels, which I can't even see even when the background under it is white.

Otherwise, my friend has a 226BW but it looks nice,but I can't say much though it seems like it's a much better panel. So you should get the 226B/CW if you don't like any of the things I posted on the top.
