Component Video Sync Problem
I’ve got a Sony Broadcast monitor that I’m trying to hook up via component from a blackmagic intensity pro card. The monitor works fine when using the composite or s video connections but it appears to need external sync when using the component connections. I’ve tried hooking up a dvd player and I have the same problem. The bm card does not have any sync connection. Does anyone know of a way around this? Am I missing something in the connection process or am I just out of luck with this set up?
Any help is much appreciated.
thanks.

NTSC Component, by definition, contains all you need to lock up a monitor in the three signals.
from WIKI:
Component video is a video signal that has been split into two or more components. In popular use, it refers to a type of analog video information that is transmitted or stored as three separate signals. Component video can be contrasted with composite video (NTSC, PAL or SECAM) in which all the video information is combined into a single line-level signal. Like composite, component-video cables do not carry audio and are often paired with audio cables.
When used without any other qualifications the term component video generally refers to analog YPbPr component video with sync on luma.RGB, on the other hand requires a fourth cable supplying sync.
from WIKI:
RGB requires an additional signal for synchronizing the video display. Several methods are used:
composite sync, where the horizontal and vertical signals are mixed together on a separate wire (the S in RGBS)
separate sync, where the horizontal and vertical are each on their own wire (the H and V in RGBHV)
sync on green, where a composite sync signal is overlaid on the green wire (SoG or RGsB). -
Ok. I’m hooking the component cables up to the RGB inputs. The settings in the menu have an option for external sync or sync to green. I have no external sync so that doesn’t work. If I choose “sync to green” the picture comes through but it’s all green. I’m guessing my monitor isn’t going to work with the BM card component signal. Can someone confirm this for me?
thanks.

It sounds like you have the monitor in RGB, not in YUV (aka Y,Pb-y,Pr-y). You leave the cables connected the same way, but you need to switch the input in the menu or front panel.
Which monitor is this, anyway?

The monitor is a Sony PVM-20N2U. It is in RGB mode and I can’t find an option in the menu to put it into YUV. There aren’t any physical switches on the thing either. Any ideas?

You do know that this monitor will not display HD, right?
I don’t know the menus of that monitor, but I do know that it can display YUV when it’s set properly.

Yes. I’m just trying to get an SD signal on there. I looked the model up online and it doesn’t look like it does YUV. I’d love to be wrong about that though so if anyone has any idea how to do it, please let me know.
Thanks,

I like to know this as well!!
