I am actually considering returning the L226WT I bought last week. I've been having nothing but problems with it. I had the viewsonic 22" but returned it hoping the LG was better. Judging from my experiences, I cannot recommend this monitor at all.
Non TN-related problems:
1. Very poor out of the box calibration - I had to severely shift the gamma curves - way too much blue. I was able to use the calibration tool and get a reasonably accurate picture - but not perfect. I had never seen a monitor so far off.
2. Confusing Sharpness tool - now I can never tell if it's quite sharp or not
3. Random blacking out - screen flickers and sometimes shuts off - shows half the screen with the backlight fully lit and the other off - could be a defect! I've actually had to power down several times so the screen will come back.
4. Syncing problem with forteManager software (calibration tool that comes with it) - the screen appears in broken chunks - fixes itself when I turn the screen off and on again. Could also be a defect.
5. Buttons are very difficult to press. They are located in a strange place.
6. ForteManager gives page not found errors if you click on certain tabs in Vista.
7. Very poor dark colors response - I can't see past 8,8,8. The Viewsonic 22" TN showed down to 2,2,2. (My VP930b (P-MVA) shows beautifully down to 1,1,1)
Good things:
1. Shows reds very nicely - good representation of red/orange hues from pictures and in games.
2. Doesn't have nearly as bad a TN effect when looking from below as the Viewsonic did (it showed major red halos around the pixels from as little at 10 degrees below the screen)
3. Nice bezel design - clean and functional.
