Q: 2560x1600 via HDMI? Dell U3011 monitor.

Well.. at least you received the adapter.. Mine is saying backordered. 

This is a deal breaker for me, I have the same monitor and if I can not connect at full res, that will be no good. 

Any idea what the refresh rate is through the display link/DVI ?

Great to know this worked.  I am trying to figure out the best monitor resolution I can buy and hook up to my new macbook at 60z. 

There is some good info at this site about the technical stuff   https://www.kickstarter.com/projects/kickshark/hydradock-11-port-usb-c-dock-for- apple-macbook/comments

I'm confused..   this seems to indicate it should all be possible directly via HDMI?

PS, how did you get the adapter from USB-c to HDMI?  Mine is still on backorder and not stocked in stores.

Are you able to charge your MacBook somehow while your display is hooked up?

Oh forgot you were using that adaptor.  This review of the macbook from UK says: Apple says that a DisplayPort adapter is coming soon.

Hi, I bump this old discussion because I'm about to buy a Macbook that I plan to hook up to my old Dell 3008 FWP that I have in my office. Honestly I can hardly believe a simple HDMI-DVI (single-link) adapter can handle native resolution of 2560x1600, because DVI single link (not even considering the adapter) is not able to go that high. I remember when I bought this monitor I didn't even know about the existence of DVI dual-link, so I just hooked it to my PC with the existing single-link cable (to not have to pass it again behind the desk) and it looked awful. Then I took out of the monitor box the dual-link cable, used that and 2560x1600@60Hz looked wonderful.

Maybe a HDMI-DP adapter could work? Can't find anything suitable around...

Thanks for your post; can you share with us exactly which HDMI-to-DVI adapter you used?

I'd like to know which HDMI to DVI he used as well. I had an old HDMI-DVI cable and tried it but my Dell 3008WFP is just blank. The Macbook sees it--it shows the proper resolution options, but the monitor doesn't show anything. I'm going to oder a new cable just to see if maybe my cable is bad but I'd love to know which one commasign used successfully.

I used one from Amazon, but noticed that in the macOS beta, it no longer worked. Support said that it outputting 2560x1600 over an HDMI to single link DVI was actually a bug to begin with (which explained the occasional flickering). There seem to be a decent amount of USB-C to Display Port adapters, but none that could also charge the Macbook while using DP. My u3011 is current shelved until something that supports Display Port and charging comes out. Switched to an LG 4k USB-C monitor that connects and charges using the USB-C port.
