Reviews for Mini DisplayPort to DVI Adapter

Does what it's supposed to do now for over a year, no problem. I use it with a samsung SyncMaster 2232BW with no issue.

I got this with a new MBP in May of 2012. I plugged it in to my MBP and my plain old Samsung 22" digital monitor. It works reliably. Once in a while the display gets confused and puts the main screen on the Samsung when I wake up the computer. I unplug and replug (just once) and it works fine. I take my computer with me daily, so I plug and unplug this unit every day. Works fine.

I'm using it to connect my 13" MBP to a Viewsonic VX2450vm-LED monitor's DVI-D slot. Works well as its supposed to at 1920x1080 resolution.

Ignore other reviews that gave this product 1 or 2 stars b/c they bought the wrong product.

Connected to my Sanyo Flat screen TV and made a display adjustment in preferences and it works. Holds to apples montra... It just works

Wrks perfect - a few adjustments in Preferences and was all set - took less than 60 seconds to complete

I have a late-2010 13" MB Air and was using the mini DisplayPort to VGA adapter with various monitors. It appears that the VGA timings or signal strength on the laptop are marginal at higher resolutions (1600x1200 and above). The effect is that you periodically get zig-zag bursts across the entire screen. This is the analog VGA signal slipping between scanlines.

I switched to this DVI adapter, which fixes the problem. However, I'm using a KVM switch so moving to DVI was a downgrade because now I have to switch the monitor separately. I know some Macs can output a clean 1200 lines through the KVM switch and VGA because my 2009 Mac Mini and a 2007 Windows notebook works fine with the exact same setup.

As other reviewers say, if you are using 1920x1200 or higher resolutions, get the dual-link adapter instead of this single DVI adapter. But below that resolution, this one works fine. It does not have the zig-zag display problem that VGA has.

Summary:

If you have a single monitor running at 1920x1200 or below, get this DVI adapter. If you want higher resolutions, get the dual-link adapter. If you're doing presentations, you have to use VGA but switch to a lower resolution than 1600x1200 to avoid the zig-zag problem.

Not sure why people are complaining. The adapter is sold to let those with a newer Mac with a mini-DisplayPort connect an older monitor with DVI-D, such as an Apple 23" panel. That's exactly what I needed to do, right down to the Apple 23", and the adapter works exactly as advertised.

This adapter has worked perfectly for me since I purchased it in December 2010. I use it every day, disconnect and reconnect it frequently when I move about with my laptop, and I have had none of the problems (poor display quality, problem with mouse) that other reviewers have mentioned. I have a MacBook Air and a 22-inch (G22WLk) secondary display. The secondary display is great for VPN or remote desktop work, or just to have more windows open and more working space. Use "displays preferences" (under an icon at the top of your screen) to adjust settings for remote desktop. I'm planning to buy the VGA DisplayPort adapter to work with other displays and projectors.

If had this for about 4 month now and I haven't had any issues with signal or whatever. One thing i dislike is the laughably ridiculous price tag. Apple, how can a mini display port to dvi-d cost $30 ???

Works perfect with apple products. Not with other lcd junk!
