Mini DisplayPort 1.1 + USB to Dual-Link DVI Adapter

Connect your mini DisplayPort equipped MacBook®, laptop, or PC to a Dual-Link DVI display using this Mini DisplayPort + USB to Dual-Link DVI Adapter from Monoprice.

This adapter converts DisplayPort video to Dual-Link DVI video at resolutions up to 2560x1600. Additionally, it can convert to Single-Link DVI to resolutions up to 1920x1080. The adapter is fully compatible with the DisplayPort 1.1 specification and draws the necessary power from both the DisplayPort and USB connections. Note that this is not bidirectional and therefore will NOT convert DVI video to mini DisplayPort. Also note that this does not support audio.


  • Complies with the DisplayPort version 1.1 standard
  • Supports Dual-Link DVI resolutions up to 2560x1600
  • Supports Single-Link DVI resolutions up to 1920x1080
  • Supports up to 24-bit Deep Color (8-bits per channel)
  • Draws power from the Mini DisplayPort and USB connections
  • Supports up to 268.5 MHz bandwidth

* Attention Mac Mini Customers using dual monitors only. There is an unresolved issue with using both the mini-DVI and mini display port outputs simultaneously. Specifically – when the mini-DVI cable is disconnected from the Mac mini, this causes the mini display port to not function  – often causing the display to show an “unsupported format” error. This appears to be an ongoing issue with multiple generations of Mac minis (models with mini-DVI and mini display port) and also appears to be happening with a variety of manufactures display adapters for macs, not just Monoprice adapters.


The solution – (Again, for dual monitoring Mac mini users only) Use the mini-DVI output for your main display, and the mini display port for the secondary display. That way - disconnecting the second display (mini display port) will not affect the output on the main display (mini-DVI). This will not be an issue if you are using two monitors - and are not disconnecting your mini-DVI adapter.

I've been using this adapter for a couple of weeks without problems so far, hooking up my Lenovo w540 laptop to my 30" monitor (through a KVM switch).

Hit and miss

Pros: If you get one that works, it will be reliable, and you only occasionally need to unplug then replug the USB cable for all monitors to work well. Most of the time, I have no issues with this device.

Cons: After having a flawless adaptor for over a tear, I decided to upgrade my monitor and needed a second one of these units. Ordered and installed it, but after 3 minutes, the device flaked. Worked for another minute then crapped out altogether.
It seems that these units are hit and miss. Had good luck with one I still use with no issues. And another one will be en route to the RMA department shortly. I Love Monoprice, but I wish these items were more consistently good. The failure rate is high if you read the reviews. In fairness, I don't know if it's this brand, or the device is a poor workaround regardless of manufacturer????

Looses synch - defective design

Unfortunately, this adaptor has a design flaw that causes it to loose synch resulting in the snowy screen several times a day. As you can see from these reviews, this is a common complaint. Monoprice was was cooperative in exchanging the unit for me but the problem existed on both. I also tested the units on two different monoprice monitors of the same model and two different macbook pros with the same results. So it's not just a defective unit. It seems to be a design flaw of some kind.

Turns to snow at least once a day

Pros: When it works it works

Cons: Been having the turns to snow issue daily since shortly after purchase

Unfortunately I assumed the issue was with my monitor, but after reading these reviews, I see I am not alone.

For most of the time I have owned it, whenever the monitor turns on, from sleep, it turns to snow on the image. The solution is usually to unplug the USB power, and plug it back it, to power cycle it. Sometimes I have to unplug the cable itself from my computer.

Here's a tip: pay the extra money and buy a monitor with a display port input, or buy a better adapter like the Apple one?

wouldn't buy again

Pros: When it's working it looks fine

Cons: Drops signal
Frequent snow
Sometimes just won't connect

I purchased two of these at the same time for use with an off-brand monitor.
I had assumed the issues were with the monitor, but it turns out all of these issues have been caused by the Monoprice adapters.

From day one I experienced signal drop outs and static/snow when connecting the cable. At other times the display resolution would be detected incorrectly making my Mac show the wrong resolution with nothing on the external - crazy.

The warranty period is only one year as these aren't considered cables. I wouldn't bother with these again, they've been a pain and aren't that much cheaper than the real thing.
