MXO2 with an Eizo CG241W

[mkamstra]

I'm working with an Eizo cg241w but I do not get an image on my monitor working with fcp
The eizo suppose to support 1080p
In the matrox preferences I set the hdmi out on the rgb setting.
I use also an dvi-hdmi adaptor
Do you think that I have the same issue as the apple 23' monitor or do I have to change some settings

Regards
Martin

Hi Martin,

Whenever you are trying to get an output from the MXO2 there are several important steps to go over.

In System Preferences>Matrox MXO2>Video Output>try setting the option "Set Main Channel to" to "Follow Application".
In FCP try using a Matrox MXO2 Easy Setup.
In FCP make sure External Video is set to All Frames.
In FCP select a Video Playback setting closest matching to your footage and Easy Set up.

If you don't get an output after checking these options, try restarting your system (with the monitor connected to the MXO2), then make a new project in FCP and try setting the above options again.

If this still doesn't help, the problem here might be the HDMI to DVI adapter you are using. Would it be possible to go directly from the MXO2 to a HDMI monitor? Remember that a HDMI monitor for use with the MXO2 must have a resolution of 1920*1080.

Matthew

Hello Matthew,

I have the same problem with a MacboockPro 17" + Eizo CG241W, tried all you said and checked the HDMI-DVi cable : it's working.

I tried most of monitoring playback in FCP, but there is still no image in my monitor.
What shall do ?

Thanks,
Seb

Hello Matthew,

I have the same problem with my MacboockPro 17" + CG241W, I tried all you said and check my HDMI-DVI cable, but the MX02 (with max) still doesn't display any image on my monitor.
What are the options left ?

Thanks
Seb

Hi sebper,

Is the monitor capable of displaying video at your framerate?

HDMI-DVI and DVI-HDMI adapters are not something we've tested and can't guarantee you anything when using one. The MXO2 is meant to be used with a straight HDMI cable to an HDMI monitor at a resolution of 1920*1080.

Thank you for your quick answer,

Actually, the Eizo CG241W is great when displaying through Digital Cinema Desktop Preview in FCP, so I guess it can display at 25fps,

its spec is : Analog Scanning Frequency (H, V) 24 ? 94 kHz, 47.5 ? 86 Hz
Digital Scanning Frequency (H, V) 26 ? 78 kHz, 47.5 ? 63 Hz (VGA Text: 69 ? 71 Hz)

And it was purposed for video ! "With 12-bit hardware calibration and a 6 ms response time, the ColorEdge CG241W is ideal for pre-press, digital photography, video editing, and post production."

Is it compatible with the mxo2 ?
Is there any monitor you would advise ?

Thanks again
Seb

I Have the same problem. Tried everything, but no picture on my EIZO CG241W....

It?s just ridiculous, that MXO2 doesn?t work together with an EIZO and that this hasn?t even been checked.

Just bought my MXO2, but if EIZOs aren?t supported I surely give it back and buy an aja I/O HD.


I have also the same problem. I think changing my MXO2 into an AJA I/O hd is the only option that can solve that problem. I think every user should be warned of such incredible and unbelievable incompatibilities!

Digitus HDMI Splitter not only splits the HDMI Signal from MXO2 but also seems to "clean" it in a way, so that EIZO CGW241 can read it!

and it unveils something very interesting:

You get a picture which is not 1920x1080 but 1920x540!!! Tried 25p, 50i,29,97 it?s always 1920x540 and the CGW241 can?t handle that.

Either you choose Screen Size > Full Screen you get eggheads since the CGW241 has 1920x1200 or you choose normal, then you get an 1920x540 image in the middle of the screen.

So my question is: Of what size is the HDMI Signal the MXO2 delivers:

Is it 1920x1080 or is it 1920x540 with a flag to double the vertical solution?

[Andy Mees]

The output from the MXO2 is 1920x1080. In this case it seems likely your splitter or HDMI >DVI adapter is causing the resolution issue you are seeing.

The MXO2 delivers multiple video output options, I just had a quick gander at the specs for the Eizo CG241W and it appears to accept only DVI input (is that right?). In that case you can use an HDMI > DVI adapter of course, but it must be able to generate a valid DVI signal supported by your intended monitor. As the Eizo is likely to be expecting to receive a 1920x1200 DVI input then it would appear you need an adapter that converts 1920x1080 HDMI to 1920x1200 DVI. Could that be the issue?

The EIZO CG241W does look like a very nice display by the way, but a quick look suggests the CG232W appears to be much the better choice for video work, as its a 10 bit panel with direct support for HD/SD SDI input.

Hi everyone,

Upon reviewing the Eizo CG241W spec's, I can confirm that there are two issue with this monitor when using it with an MXO2, as mentioned by Andy.

1) The monitor has a resolution of 1920*1200 while the MXO2 will output a 1920*1080 signal, and that might be causing the 'egg heads' or stretching the video. You can try looking through the monitor's settings to see if there's a 1:1 option so it shows the video from the MXO2 at the actual size with black bars at the top and bottom of the video.

2) The monitor only has a DVI input but the MXO2 has an HDMI output. You can try using a HDMI to DVI adapter, but from past experience I've seen that they don't always work and it's a hit or miss scenario. Unfortunately there are no settings we can adjust to get them to work.

There?s lots of bla bla in the answers given (sorry), so here are some facts I found out myself:

MXO2 doesn?t output true 1080p it outputs 1080psf, which means that every frame has a size of 1920x540 and not 1920x1080, as the EIZO shows up well, if you push the information button.

An HDMI Monitor always shows 1080i, if you choose a solution of 1920x1080 in the mxo2, never 1080p, no matter if you choose 1080i or 1080pfs. If it shows 1080i that also means that every frame has 1920x540
and not 1920x1080!


The EIZO also shows a picture, which has 1920x540, so it?s extremly squeezed and therefore absoulute unusable.

Pushing the EIZO, or any DVI Monitor, to full frame makes the picture too big, since the EIZO has 1920x1200 and not 1920x1080


ERGO: The MXO2 is not compatible to the EIZO CGW 241W.

[Andy Mees]

Good detective work in tracking down the apparent root cause of the Eizo's incompatibility Hazett. So is it your finding that the CG241W doesn't support any 1080i input over DVI or do you think its a specific incompatibility with the MXO2's 1080i output?

In the interest of keeping down the "blah blah" tho ...

MXO2 doesn't output true 1080p it outputs 1080psf

Correct, thats never been in question.

which means that every frame has a size of 1920x540 and not 1920x1080

Well, it means that its an interlaced video signal where every "field" has a frame size of 1920x540; there are of course two fields to every frame hence covering the full frame size of 1920x1080.

An HDMI Monitor always shows 1080i, if you choose a solution of 1920x1080 in the mxo2, never 1080p, no matter if you choose 1080i or 1080pfs. If it shows 1080i that also means that every frame has 1920x540 and not 1920x1080!

As above, and worth repeating for clarity, fields not frames ... this is the "segmented" nature of the progressive segmented frame format. The video monitor will always detect 1080i as that is indeed the format being transmitted/received.

Again, great work following through with this, its a good logical conclusion to the topic.

Very Best
Andy

A DVI doesn?t make any difference between fields or frames. What is the reason the mxo2 puts out 1080psf and not 1080p, even if you re wroking on a 1080p movie and not on interlaced material?

Splittting every frame in two fields and let the Monitor put it togehter again seems not quite understandable to me. The mxo2 causes a lot of confusion and troubles on doing so. Why can?t it put out 1080p as every DVB-T Tuner, every media box, every blu ray does, and hence makes it possible to easily convert HDMI to dvi.

Are there plans that the mxo2 will get this badly desired feature in the near future?

[Matrox_Support_Matthew]

Hi hazett,

There are several issues we're looking at with your setup that you should be aware of;

1) The MXO2 has an HDMI output and not a DVI output so there's a conversion being done between the MXO2 output and the monitor.
2) We don't support HDMI to DVI adapters and THAT could be the issue, not the MXO2's PsF output.
3) Your DVI display has a resolution of 1920*1200 and not 1920*1080 which is what the MXO2 outputs (the two 1920*540 PsF frames combined as Andy explained make 1920*1080). This means if we output 1920*1080 and the monitor is set to 1920*1200, it will stretch the image to fill the screen. This setting on your monitor might actually be called FILL and most monitors have other options. Check if your monitor has a 1:1 option where it should display the 1920*1080 at 1920*1080 with black bars at the top and bottom of the image to make up the difference between 1200 and 1080.
4) Not every progressive output of the MXO2 is PsF. See the Supported Output Formats section of Matrox MXO2 User Guide for more details on this.

As for getting an option to always output P instead of PsF, I suggest you make a post about this in the product feature enhancement section of the forums.

Matthew

This is what I call a bla bla answer. You give no new information, and you do not answer any question of mine. You just repeat everything that already has been said.

Big Congratulations to matrox for that!!
