Hello,

I just got an EIZO reference monitor (CG series), which has 2 DVI and 1 DisplayPort inputs. My platform is Mac Pro.

When I try to feed the monitor with the signal from the DeckLink, either directly through the HDMI output or converted to DisplayPort using the HDLink, the monitor does not receive an usable signal.

If the HDMI is used with a DVI converter, the image received is PINK. If the DisplayPort is used directly from the HDLink to the port in the monitor, there is no signal that the EIZO can process, so black is display.

On the other hand, if the EIZO is connected directly via DVI from the computer, the image is display perfectly. However, this defeats the purpose of using it as the reference monitor.

Is there a known issue and a way to correct it with this particular configuration? I have used multiple cables to assure that the cables are not the problem. Please, advise ASAP!

Thanks,
 
Could this be a PsF versus P issue?

Not sure, but seems more an issue of YUV vs RGB due to PINK image.
 
Long shot here...

Is it a 30"?
If yes do you use Dual link DVI cables?
 
Sorry misread, when you connected directly to the computer with DVI it works. (So it isn't that cable.)

In the HDLINK Software you can set it do display YUV or RGB b.t.w.
 
Sorry if I am missing something, but where exactly within the HDLink you can select the YUV or RGB signal type? It seems that it might be what fixes this issue.

Thanks!
 
I have an older HDlink don't know if it is still the same.
if you connect the HDLink with usb through the software... (I am not at the office right now, so can't explain step by step)

My software does not have that for HDLink. The DeckLink does have "Use Betacam YUV".
 
You talk about a DVI converter... what do you use?
 
HDLink with DisplayPort.
 
I meant from the HDLINK you go through HDMI OUT > To EIZO DVI. (You talked about a converter, or you you mean a HDMI to DVI cable?)
 
My HDLink has HD-SDI input and DispalPort output. From there, I can run a DysplayPort cable to my monitor, which has a DisplayPort input. But it is not sending a signal that my monitor can use. So, the question is, is that signal RGB or YUV?

What's the model number of your Eizo display?

CG223W, which offers not just sRGB, but Rec709 and DCI color spaces, among others. Aside, it is advertised for "moving images".
 
Dwaine,

My JVC that I am replacing has the same resolution and has no problem scaling down. If I use the EIZO DVI it does the scaling without a problem. The question is why the DisplayPort does not show an image (we have tried MANY cables), and if I use the HDMI out from the DeckLink and connect it to the monitor using an adapter, why it is showing a PINK image.

Please advise,
 
Honestly, if you are trying to use your new panel as a reference display you should be sending it a proper HD-SDI signal. DisplayPort and DVI inputs are hard to trust. The HD Link will also skew any proper signal, especially if you are using a DVI to HDMI adapter.
 
Display Port support has been wonky for me in several setups. For example nVidia Quadro 4000 on Mac to DreamColor via DP is a total fail, but works via DVI or DVI to HDMI crossover.

Display Port might be a great interface technically, but I've been disappointed with the level of support from multiple vendors - I don't think most of them care.

Cheers - #19

That is what I currently do with my JVC which has HD-SDI. What I am trying to do with the new EIZO, that does not have HD-SDI, is to funnel the signal from the DeckLink HD-SDI to the HDLink to convert it to DP. DVI is not an option for reference monitoring since it displays only 8 bit images. DP is capable to do 10 or more bits, hence it is the preferred signal input after the HD-SDI output.
