    Works Every Time.

    Pros: Low cost,
    Works every time (so far),
    Great item for my bag-o-tricks

    Cons: I only have one (so far...)

    I work in AV support at an educational center. Presenters can come in with any of the recent and not-so-recent video connection standards. This little gem has worked without fail each time I have used it, unlike a more expensive brand purchased elsewhere.
    Mac, Dell and HP, no problem. Ordering more to eliminate conflicts caused by having only the one we ordered first as a test.

    This worked for about 45 minutes and then failed completely. The computer stopped recognizing that it had a monitor connected at all. I was using standard VGA monitor.

    Doesn't work on Dual Link DVI 2560x1600

    • Mac User,

    Pros: Many output formats

    Cons: Not working on Dual Link DVI 2560x1600. MP need to take down the claim that it does. What a waste of money

    I brought this to use with my DELL 3007wfp with new 2015 15-inch macbook pro. Sadly, i can't get the dual link DVI feature ( as claimed here) to work with the monitor.

    The monitor works perfectly fine with my old mac pro with 2560x1600 so i can confirm it's not the issue here. I have tried dual monitor setup, single monitor, with thunderbolt 2 hub and directly connection from MBP to the monitor though this cable BUT nothing is working. Using the hub, the extra resolution shown up as selection but all i got is black screen snow, looks like sync frequently problem if i were to select anything more than 1280x800 - which is the single link DVI resolution allow for this monitor.

    So no, this cable doesn't work as dual link DVI.

    Mark. I will need a refund for this product. It's not longer working. I've used it on 2nd monitors with lower resolution which works fine until today. Connection keeps breaking and soon enough, nothing but snow and monitor not longer sync. I tried different cable with same result, tried different adapter which works fine so that conclude this adapter is bad.

    First it doesn't work on Dual Link DVI 2560x1600, now it doesn't work on anything. Not a good experience
