Dual Link DVI to 2016 MacBook Pro options?

Ok, thx for highlighting that out.

Returning the overpriced thingy to apple mañana, and ordering the @mmaaxx itanda solution thru amazon.

This will be my 4th cable to try out. Hopefully 4-time's-a-charm....

I have a late 2016 Mac Book Pro and a Dell 3007WFP. I was able to get it to work at 2560x1600:

-Buy an iPad 10W power adapter and connect it to the USB side of the cable pair going into the Dual Link adapter

-Buy an Itanda USB-c to minidisplayport connector (Amazon) and connect to minidisplayport side of the cable pair going into the Dual Link Adapter.

I think I have found an alternative solution that doesn't need aditonal power from an iPad charger. I had the same problem with my Macbook Pro 2006 15 inch and HP 30 inch dual dvi monitor,

I tried to purchase a usb-c to minidisplayport adapter in Holland, but could only find a usb-c dock called Hyperdrive with a mini displayport. It also has usb-c power in and usb ports.

I ordered one and I'm totally happy. I can tell this works with the mini-displayport to dual dvi adapter and gets you 2570x1600 and more. Not exactly cheap, but with this solution I have one mini dock which plugs in:

- minidisplayport to dual dvi adapter

- the usb cable on the dual dvi adapter

- keyboard+mouse

- Usb-c power supply

- And there's a cardalot left.

if somebody's interested I can send a picture.

I have not been able to get my MBP 13 2016 to work with HP LP3065. I have used the StartTech USB-C->DVI/dl (and others like it), I have also used the Apple TB2->TB3 connected to the Apple TB2->DVI/dl as well as the StarTech TB2->DVI/dl. In some cases I could get it to recognize the monitor but not get above 1280 x 800 resolution (whereas my MBP Late 2013 can drive it at 2560 x 1600 along with 2 other Dell U2715H at 2560 x 1440).

I am guessing that the Intel Iris Graphics 550 1536 MB shared isn't enough to drive it at those resolutions?

It looks to me as if the TB3 -> TB2 adapter is needed but won't support DisplayPort devices. From the adapters support page:

Thunderbolt 3

For Mac models with Thunderbolt 3, you can use a use a Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter to connect to Thunderbolt devices like displays and external disks.

Note that although it uses a Mini DisplayPort connector, the Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter doesn't support connections to Mini DisplayPort displays. Also, this adapter supports only one powered Thunderbolt 2 device on a USB-C equipped Mac.

First of all, you don't need the Thunderbolt 3 to Thunderbolt 2 adapter, because you're going to be using the USB-C port in DisplayPort mode.

You may want to give the IOGear USB Type-C to DVI Adapter (GUC3CDVI) a try, it appears to support dual-link DVI. It is bus powered, so you don't need an additional USB connection.

You may also be able to kludge together a bunch of adapters in order to keep using the adapter you already have, but that would be messy and expensive.

It looks to me like this US$16.99 adapter from USB-C gives you the Mini DisplayPort at high resolution:

USB Type C Adapter, AllSmartLife® USB C Type to Mini DisplayPort/Mini DP Adapter Cable With Aluminium Case Support 4K resolution for Apple New Macbook, ChromeBook Pixel - Grey

The data on the USB port is only used for the Brightness slider. If you don't need that every day, Users have reported you can get the needed power (to power the Apple Dual-Link DVI adapter) from an iPhone charger or similar inexpensive USB charger.

Same problem.

I've looked into the IOGear USB Type-C to DVI Adapter (GUC3CDVI) and the AllSmartLife Adapter mentioned here, and neither of them solve this problem.

However, I note that DVI-D (AKA "Dual Link DVI") is supposedly compatible with HDMI. If that's true, it may be possible to use an HDMI converter. Weirdly, it's very hard to find male HDMI to female DVI-D converters... closest thing I can find is this, but it's a crapshoot:

It might be that this Monoprice adapter handles DVI-D, though that seems doubtful:

It might work to plug your current adapter into a mini display port + usb adapter such as:

In re-reading, I see that my response above was not perfectly clear.

Once you have Mini DisplayPort at high resolution (by using the US$16.99 adapter I cited above), you are back to the equivalent of your old Mac's Mini DisplayPort output.

Then connect that to your existing Apple Mini DisplayPort to Dual-Link DVI adapter. The only part left to solve is there is not yet a USB input, which provides Power for the DVI adapter and USB to the display. I recommend you use an iPad charger to produce the needed power, and unless you need to change the brightness, you should be good to go.

If you regularly need to change the brightness, you will also need a USB-C to USB adapter or dock as well. Whatever "regular" USB hub/solution you use in the long run should work just as well for this.

Hopefully you're right, Grant! (Crossing fingers)

I was worried by this question and answer on the AllSmartLife Amazon page:

Grant, it looks like you're absolutely right about (at least my) Dual link DVI-D monitor. I just tried unplugging the USB part of my current adapter from my 2011 MacBook Air and plugging it into an ipad/iphone charger cube, and it works great! OMG, I always assumed the USB connection carried information! Maybe it only does at higher resolutions and frequencies than mine? (I'm running at 2560x1440, unclear what frequency)

Thanks, this is hugely encouraging!

I'm looking at the same problem. I have a Dell 3007WFP at 2560x1600 and found this Startech adapter that I think I'm going to order. It's all I've been able to find so far...

https://www.startech.com/uk/AV/usb-c-video-adapters/usb-c-dvi-adapter~CDP2DVI

Startech has been a trusted early supplier in the land of adapters for Apple and AMD display protocols. If they say it works up to 2560 by 1600, it likely does. There is more power available from the USB-C port than just a Mini DisplayPort, so they can eliminate the USB formerly required for powering the chips in the adapter.

But two "magic words" formerly prominent with adapters like these are missing. They are not calling this an "ACTIVE" (meaning re-driven signals) adapter, and not saying anything about "Dual-Link DVI".

This is also a little troubling:

Note	Some legacy DVI monitors may be limited to a resolution of 1920x1200 when used with this adapter
