Green Screen Problems, not green screens, monitor Green Scrren!!! :)
Hi everyone,
We are having a bit of a problem here with one of our editing machine. It started 10 days ago, the two windos of FCP, I don’t know how they are called in english, the Canevas and the visualliser(?). They started to go green sometimes.
We’re editing on a quite recent mac pro 8core, 12go of Ram, with a Intensity Pro Card from Black Magic. all the edited material is on a 6to SAS RAID with an ATTO controller card.
I recently changed the card to a Multibridge Pro by Blackmagic, the problem went on, but even more explicit than with the Intensity Pro, as now as the Green goes also to the external HD monitor, also hooked to the multibridge. And when that happens it goes with sound like BZZRRR. Not cool.
The problem is not constant, it happens at one moment, and suddenly not for 2 days, than one day is a nightmare.
Any ideas would be most welcomed, as I never saw that problem before, I don’t know how to handle it!
Thanks in Advance,
Max

Hi max,
The green is the color of the sick card.
What is difficult to determine from here is: which card?
Your GPU or the BlackMagic?
I would start by e-installing the BM drivers.
If the problem persists, unmount the card and see how things works.
If the problem disappear, knock in the BM forum and ask what’s wrong with your Multibridge Pro.

Hi Rafael,
Thanks for your input!
Sick cards… arf… the Macpro is very new… Well it happens no?
My thinkings: The Mac used to have a Intsity Black Magic card – > Green on computer monitor. (The intensity is a cheap card (too cheap?) with a HDMI connection to the HD monitor. The HD monitor did not go green.
I changed it recently to a used Multribridge Pro previously installed on an other MacPro where there was no problem. The problem continues but now there is also a green problem on the HD monitor. The difference is that it is linked with an SDI connection. Maybe the previous HDMI connection did not know what the green was and did not transmit it.
So I would say that the BM cards are not involved in this problem.
The Graphic card? It’s the preinstalled Nvidia Geforce GT 120. Does it have any influence on FCP and the dealing with HD (or other) video materials? I couldn’t say.

This is the card that control the monitors you have connected to the DVI of your Mac.
When these cards go nuts quite often they start to make green pixels in the screen.
Full or half green screen is also typical when the IO’s cards malfunctions.

ok, but as I said, the green surfaces are only on the Canevas and the other video window of FCP. If the Graphic card was out, it would be on the whole screen! Wouldn’it?

The behave of the GPU when start to fails is quite erratic. Some times you get some green pixels in very colored images, some times is a pattern in the whole screen, some times disappear..
With both cards installed is difficult to figure out were is the problem.

Quit FCP. Trash your fcp prefs, your tuhmbnail and waveform cache, and the constant frames which are located on your scratch disk in the render files folder.

Done… nothing changed.
I removed the all BM cards and drivers using only the GPU. It is having a it of hard time as we working with HD material. Nevertheless no more green flashing. But of course the render on the monitor which is now a computer monitor is far less good.
I posted the question in the BM forum.
Thank you for your inputs!
