The only TNs I would get are Samsung and LG. Ive seen AUO and they look washed out. I have to samsung panneled dells in front of me and they are good monitors but the blacks arent the best but they are as good as it gets for TNs.
ive seen some horrific tn panels too, but the 225bw is beautiful looking. i absolutely love how fast the refresh rate is, clearly the biggest advantage tn's have. the light bleed though... what a damn shame.
