    I have one of the new macbook pros and plugged in the display port to dvi adapter and connected it to a 20inch viewsonic monitor and nothing happened. I then connected my daughter's 1 year old macbook with a mini dvi to dvi and it worked perfectly. Two visits to the apple store and a call to apple support yielded no answers. Wondering if anyone else having an issue?

    In the land of no hills and red dirt.
    I've had an issue with the cursor jumping on the external LCD monitor hooked up to alum MB with DVI....

    The geniuses at the applestore told me it was due to my monitor...I told them it was funny that the same monitor hooked up to a powermac g5, mac mini core duo and white c2d iMac with NO problems.

    I'm not the biggest fan of apple geniuses at this point....

    Help! Same Challenge - DVI monitor NOT WORKING with New MBP

    I have a Viewsonic VX2035WM widescreen monitor... works GREAT with my son's MacBook Pro - last year's model... but will not work with my new MPB just bought this week. Apple says port works... Viewsonic says monitor is fine... I say it's not working.

    Works fine in VGA mode (ugh)... but NOT in DVI.

    Yes, I have the adaptor.

    Help!? Please?:confused:

    Problem is the new macbook pros use a different adapter. It looks the same, but it isn't.

    Mini DVI to DVI adapter WILL NOT WORK on late 2008 Unibody MPB.

    I was given the Mini DVI to DVI adapter from Fry's when I bought my Macbook Pro when I bought it, and took it back because it didn't work. I then found out that the unibody actually uses a mini display port to DVI adapter which is slightly different than the mini dvi to dvi that works on the older macbook pros (which explains the other models working). Here is a link to the correct adapter on Apple's website:

    This is the incorrect adapter you are trying to use:

    There is a $10 price difference, but it's the only way to make it work.

    I haven't ordered mine yet, but I will be soon enough.

    Good luck!

    Has anyone made any progress on this issue? I've got a unibody Macbook Pro that also refuses to work with a 20" Viewsonic through DVI. It looks like VGA will work, but I haven't bought the VGA adapter to try myself, I'd much rather not take the degradation in quality.

    DirtyDan, if you read prairiepath's post you'll see that they're already using the Displayport adaptor.

    Still not working...

    I've had the machine in to Apple... I've tried everything. VGA works fine (alas, in VGA Mode :()... but DVI just won't work.

    Sure would like to solve it... I feel like I'm working on a PC.

    New (Jan 2009) MacBook pro... mini display port to VGA adapter and mini display port to DVI adapter...

    I just got today my macbook unibody aluminum base model and the mini displayport to DVI-D Dual Link cable doesn't work on my viewsonic VX2035wm with a DVI-D Single Link cable, I'm tempted to try and get a DVI-D Dual link cable to see if it works.

    have you guys tried the DVI-D Dual link cable??????? maybe that will fix it since the Viewsonic LCD came with a Single Link cable ='(

    here's the pics so you don't get confused:

    Yes, there's 3 variations:

    DVI-D (Digital)
    DVI-A (Analogue)
    DVI-I (Integrated)

    tried Dual Link and I can confirm it doesn' t work, had to buy a mini displayport to VGA cable, it works but the quality feels like a windows machine.

    Hopefully they will fix this.

    New DVI's

    I've seen this with my 2009 Mac Mini. I can't explain it. Its embarrassing because it simply should. VGA works fine. Other monitors output fine.

    I have a wee theory. I think monitors with VGA connectors require the analogue signal within the DVI port. My theory is the Mini DVI to DVI doesn't hold the analogue data on it. Hence the VGA monitors with DVI only work with VGA.

    I'm happy to be proven wrong.

    I was glad to find this discussion. I got my macbook pro in late 2008 and have been trying to use a Viewsonic VG2030wm. I have the right mini display port to DVI adapter ($29) from the mac store but it's not working with the Viewsonic. I believe I've tried everything except what giodelgado suggests.

    I see this on the mac store:

    for the mini display port to VGA:

    I got used to the VGA quality now, have been using it since I got it working =/, one thing to do is also calibrate the monitor in advanced mode.

    Your Mind
    I am in a similar situation where I am trying to output my audio and video from my late 2008 aluminum macbook pro to my 46" Samsung LCD TV. I've read about the problems with outputing to a monitor, but should I forsee the same with my TV and a DVI-D adapter? I haven't purchased any cables yet solely for this reason.

    Also, I have seen some mini displayport to HDMI adapters out there. If I used this connection, does anyone know if it would output audio as well (my thoughts are no)? Or if I used the HDMI, could I still run audio through the coaxial/earphone jack configuration?

    Update: Viewsonic DVI Still Nonfunctional on More Recent MBP 13

    Mac: MBP 13 MC374LL/A
    DVI Adapter: MB570Z/A (A1305)
    Monitor: Viewsonic VX2035wm

    Using a VGA adapter, MB572Z/Z (A1307), the laptop's display becomes disabled however the Viewsonic is detected and functions normally (1680 x 1050). I'm not certain this is normal behavior for external VGA displays.

    I've access to a variety of other monitors, so for me, it's not a big deal. For Apple, assuring hardware validation across a sufficient number of displays seems an obvious best practice.
