because cameras for tv record at lower frame rates than whatever they're recording, usually monitors, so there usually appears big bars moving down the monitor because it's catching only some of the vertical refreshes of the monitor, and looks bad.
Yup. Haven't you ever watched the news on TV and when they show someone with a computer monitor or TV on behind them and you see bars moving down? That's why. You can hardly see the intended stuff and it looks detracting. That's why they put in simulated images instead.
good example is the news. when you watch the news and they have a story about computers or something they always have the huge bars running through the monitors...that and because electronic commercials are nazis.
damn you alvino, same though different post time lol

They would have to sync the refresh rate of the screen and the camera or it would flicker. Plus its an excuse to show a much sharper image than in real life
