I need some really quick advice this morning. I purchased the RCA Best Buy $999.99 monitor about 3 weeks ago. I wasn't thrilled with the PQ on the SD channels and arranged for it to be exchanged with a Toshiba 51HC85 monitor. Since then the PQ seems to have gotten slightly better with the RCA. BB is delivering the Tosh in about 2 hours unless I change my mind. The PQ looked better on this set in the store. Will there be a significant difference between these 2 sets, or am I just whistling in the wind? Help me decide fast, please.
