View Full Version : Overscan

I'm not keen on the fact you can't see the whole image in the LCD. I've used firewire to monitor the full image, but I don't have a proper LCD monitor yet. So, dumb questions coming up.

If you use the component output do you get the full image?
What about the composite?
I tried a cheapo in-car LCD screen and that didn't show the full image either. Other than through firewire is it possible to see the whole image?

Guidance please!

Hi Simon. I would say it's just the monitor that hides the edges of the frame so which video output you select won't really matter. CRT production monitors use to have an Overscan/Underscan setting that allowed you to see the entire frame. Not sure about "proper" LCD monitors because I don't have one either.

Have you tried it with one of those CRT monitors then? Does the 'missing' part bother you or do you use firewire monitoring?

...I've just had bas experience of microphones creeping into shot...

You get the full image with the component out. I am running component out to a LCD TV (not the car models) and I ge the full image onscreen. I cant comment on the other outputs.

Hi Bill. What you see is a function of the panel design. Since the video is an analogue signal and the display is digital, there is an A/D conversion involved and the timing point for sampling the active video may not be consistent from panel to panel. Overall though, there should be much less overscan compared with a CRT.
