    I have just purchased the Hazro HZ27WC 8-Bit 27" LED Widescreen Professional Glass Monitor - Black http://overclockers.co.uk/showproduct.php?prodid=MO-011-HO

    I am having problems with the display. It successfully picks up the monitor and I can see the dual screen working, however it is very heavily pixelated and grainy and a fixed 2cm black line is displayed horizontally just below the middle of the screen.

    I have one of the first macbook pro 17 inch laptop with a NVIDIA GeForce GT 330M which should be a more than sufficient graphics card.

    I am using a Apple Mini DVI to DVI Adapter to connect the Dual Link DVI Cable to my macbook pro. http://store.apple.com/uk/product/M9321G/B

    I have no idea what to do now. I have reconnect all the cables and it doesnt work. I have followed all the instructions in the user manual.

    The resolution of the monitor is 2560x1440 Resolution. Can the apple mini dvi to dvi adapter supply this from my macbook pro?

    Same problem

    I have exactly same problem (MacBook Pro and Hazro HZ27WC). I even sent my monitor back to Hazro and they sent me new one but bad picture and black line is still there! Have you or someone else find solution to this problem??

    DVI is only good for resolutions up to 1920x1200.

    Higher than that you need a minidisplay port to dual-linkDVI adapter http://store.apple.com/uk/product/MB571Z/A?fnode=MTY1NDA5OQ

    Best bet to run a high-res non-apple monitor is getting one with display port. My Dell U2711 works great with a cheap mini-displayport to displayport cable at 2560x1440.
