Bought an HP Monitor yesterday, it has a DisplayPort input only, so purchased a StarTech DP2VGA adaptor to run from the monitor.Then I attached a VGA cable from the monitor adaptor and plugged directly into my mini VGA adaptor I have on the macbook.

 

I cannot get anything to display on the monitor. Through Displays on the mac, it does seem to recognise the montior is plugged in and selects the right resolution for it, but nothing appears on the monitor itself.

 

My macbook is a late 2011 model with a thunderbolt display port

 

Any ideas what I am doing wrong ??!??!?!

 

thanks


MacBook Pro, Mac OS X (10.7.3)

    What inputs does the monitor have?  What are you getting on the monitor, a totally blank screen, a message along the lines of 'no input detected', or the spiral galaxy desktop?

    You shouldn't be converting to VGA and then back again — that introduces a lot of needless complexity and possibilities for trouble into your connection. You need a cable like one of these to make a direct connection from your computer to your monitor, with no adapters involved:

    Thanks for replying, it is the HP Elite L2201 - it only has a displayport input. I get nothing at all on the monitor totally blank and the light on the monitor stays in stand by mode...

    When the monitor is connected do you get the 'Arrangement' tab in System Preferences -> Displays?

    No arrangement tab at all...

    The Mac is not recognising the external display. Can you describe in detail your cabling set-up, or better still post a picture.  Eww might be right when he says that you may need to simplify it.

    Thanks for your help think Eww is correct

    I have this same problem with my HP monitor. It is not recognized by my mac, even when I purchased a DVI to HP displayport cord.

    Help? Is there something else I should check?

    Help is appreciated!

    kehaufromaz-

     

    You cannot convert DVI from a computer to Displayport on a monitor without a device that costs about US$150 and has its own power supply.

    Hey everyone- this is my 1st time on here, was wondering for those who bought this monitor (HP elite L2201), is it compatible with your mack book pro?? I bought mine late 2011 if that makes a difference. i've bought a monitor before considering this one but the resolution just didn't match up, and had to return it after trying several things. 

     

    In general how would you know if a monitor would be compatible without having to purchase it and fiddling with it. What specs on the monitor and my macbook pro should i be looking at for campatability??

    Hi,

     

    I have a Macbook Pro from 2008 with DVI output only. What will I need to connect my Macbook to this HP elite monitor?

     

    Are you certain I will need that device, and can't just use a cheap $10 DVI to DisplayPort cable?

     

    In other words, are you saying that I need this device ($65), and can't just use this?

    zale123-

     

    You have it about right. that Atlona was US$150 now on sale for $65 device can create a Mini DisplayPort, and you can get a cable or adapter to convert to "regular" DisplayPort if needed, signals are the same.

     

    The DVI/Mini Displayport device you referenced second works only for a Mini DisplayPort computer to a DVI display. (Not that the DVI connector is also the wrong "sex" for your computer port, and just adding a cable will not fix the underlying problem.)

    DsiplayPort is completely different from interfaces that came before it.

     

    DisplayPort and Mini Displayport computer ports can be coaxed into "DVI compatability mode" by asserting a signal back toward the computer-end. This almost solves the problem (except for the amount of power needed to push the signals up to DVI levels, which can be a problem on other Macs, but should not be on a MacBook).

     

    If you have DVI on the computer, but want [Mini] DisplayPort at the display, the Atlona device is about the only way to get there.
