Do I really need a broadcast monitor if...

Hello

Do I really need a broadcast monitor if the final delivery is just going to be played back via web or computer hard drive? By broadcast monitor Im also including the monitoring solutions presented by Matrox MXO and MXO2.

I was recently asked this question and didn't really have an answer. Personally I would say that its best to have some idea what your image is looking like and as such its worth getting something like an MXO and an LCD screen. (Workflow dependent of course)

But is that really true? Can one, say in a small corporate set up, go without if they are only going to produce for web and computer playback?

Good idea? Bad idea? Pro and cons?

Sincerely
Daniel
