Getting a 3rd Video output (TV Monitor) from GTX 970
on Sep 25, 2018 at 8:40:12 am

Hi I have a dual monitor setup on my workstation.
I would like to put a 3rd TV Monitor (full screen) to show the preview.
Can anyone here answer if it's possible? or do I need a simple Black Magic card to have this setup?
My good old GTX 970 is capable of outputting 4 screens...
I am a bit confused.

I would like to have a final outcome of Dual monitor for work and a 3rd screen o show the video output preview. a pretty common setup.
I hope I am clear.

Thanks so much!

[Adam Lewen] "I would like to have a final outcome of Dual monitor for work and a 3rd screen o show the video output preview. a pretty common setup."

In Preferences > Video Preview, enable "Mercury Transmit," then select one of the 3 monitors attached to your system as the output device. You can then use the forward slash on the numeric keypad to toggle Mercury Transmit on and off.

If you're connecting to a professional video monitor and want to use it for accurate signal monitoring, you will need a video I/O card like Blackmagic or AJA.

So basically, GTX970 with 4 outputs might not help me, and a simple black-magic will do the trick?
(GTX 970 is what I have now on this machine...)

What are you trying to accomplish? What kind of display are you monitoring with?

Walter I think I got it ☺ Mercury Transmit will do OK but not accurate for a professional monitoring. (right?)
Unprofessional in what way? sync delay? Color?

Thank you! the web is filled with a lot of cross-info :)...

Ae's color management system makes the comp viewer color-accurate, if and only if you're using a color-managed workflow and you have accurately profiled your monitor. I'm honestly not sure how Ae's color management system works with Mercury Transmit; I've never tried.

If you have a calibrated broadcast monitor, you want to bypass the video card and color management system and use a video I/O card. You could also use video I/O to monitor interlacing if that's important to you.
