    He guys,
    I have an urgent question about beaming.
    I have a beamer connected to my 15″MBP 2.66GHz Intel COre i7, through mini display port to HDMI.
    But all my images display to dark.
    If I play from a friends MBP 13″, it plays back fine.
    But I need to work on my MBP to adjust the exposure for the theaterplay the video is for….
    If I drag a ‘official’ other movie onto the external screen ( the beamer) also this plays to dark.
    So there is something wrong with my output.
    How can I calibrate that?
    If I open calibration for the beamer and do it on the beamer screen…it is still to dark. Only if I completely overexpose it there, it looks better.

    What am I missing?? Where can I check?

    here some info about my second graphical card:

    Chipset Model: NVIDIA GeForce GT 330M
    Type: GPU
    Bus: PCIe
    PCIe Lane Width: x16
    VRAM (Total): 512 MB
    Vendor: NVIDIA (0x10de)
    Device ID: 0x0a29
    Revision ID: 0x00a2
    ROM Revision: 3560
    gMux Version: 1.9.21

    Thanks for all thoughts and help,

    greets, jess

    You need an output device…like the Matrox MXO2 Mini. that is your cheapest option to getting a video signal out…a PROPER video signal. OH, but it is Express34, unless you have that, and most 15″ MBPs do not, you can’t use that. Then your only options are the Motu V4HD and AJA IO HD.

    Thank you Shane,

    I still don’t understand,
    how come that the 13″ MBP plays everything fine?
    And should the beamer not play a normal movie just fine? I am not really talking about a GREAT image, just one on which everything is visible and not a way to dark image…

    It feels as if I am overlooking something..

    Does the other monitor look dark with other things too? QT movies? Pictures? Compared to your monitor? If so, then it isn’t calibrated.

    You should get a decent image if the monitor is set up properly.

    The other monitor plays to dark with everything I send from my computer (movies, pictures….) But it DOES play fine with another 13″ MBP and with exactly the same connections and adapter. (mini display port to HDMI)

    I tried calibration: Opened calibrate on the other monitor and tried to get the apple invisible in the stripes, but it is not possible! So the image stays to dark….only if I completely overexpose (with this apple image in calibration) the final image is good…

    A question: Do I have to calibrate with the calibration window on MY screen or on the EXTERNAL monitor screen? I did the second option till now..

    AND if the calibration of the monitor is not right than how come it plays fine with the other MBP?
    It must be my output!???

    thanks!

    Well, the calibration is for the signal going out…so one MBP is fine, the other isn’t. Might be a port issue, might be that it isn’t calibrated right. You need to calibrate that other monitor, ON that monitor.

    calibrate on the other monitor is what I did, but it was impossible to get the apple invisible…it was out of range……so I assume a port issue. Does that mean a hardware issue?
    I guess, I ll have to go to the shop tomorrow..
    hmpf. How to work on now? 2morrow night audience is going to b there…

    thnx Shane, in any case 🙂

    AHHHH, something else comes to my mind: Before I worked with THIS Beamer I worked with another a few days earlier (but then with mini display port to VGA) but there my image was fine!! Immediately when I switched beamer (in the beginning still with VGA) the image was dark. I switched back and the image was fine. So, is a port issue still possible then?

    And if it is about calibrating the monitor, how can he play fine with the other MB without being calibrated there as well?

    thnx Shane, in any case 🙂
