E207WFP vs E228WFP

Ok, I bought a XPS 410 system fully loaded (almost, lol, but close enough) and I purchased the 20" flat wide screen moniter (e207wfp) and thought it was a bit small. So, I ordered the 22" (e228wfp) and much to my surprise, it wasn't as crisp as the 20" screen. Perhaps it was because I just started it and it needed to adjust but I still believe that the 20" looked much cleaner. Anyone here have both or purchased both at one time and can tell me what they know? I have packaged my 20" already but am thinking of taking it back out and making a side by side comparison. BTW, both were connected via VGA aswell. The 22" screen also didnt center correctly on the screen and I had to adjust it manually and lower the brightness aswell because it was WAYYY too bright. Did I get a faulty 22" or do they usually have these little hiccups?? Which of the 2 have a better track record? Any help would be greatly appreciated! Thanks in advance!
