Query: Works great for us

There were alot of bad reviews for this monitor which made me nervous at first since I knew I had gotten this one on my gift registry... but it has always worked very well for us. I gave it four starts simply because one time I turned it on and it had waves on the screen, but the next time it didn't... must've been interference from somewhere. It is quite expensive, but we have been very satisfied with this model.
