Retina MacBook Pro External Monitors in HiDPI mode?

[rapids41]

Hi,

just tried 2 hours to get my Eizo 30" SX3031W to work with the Retina MBP and the Apple DisplayPort to DualLink DVI Adapter.

The Problem is at every resolution highter than SingleLink the screen looks like I have a broken cable! Tried some settings with SwitchResX, but nothing works.

Any suggestions guys?

EDIT: it was a bad cable now it works!

Bizarely, if I choose "Best for display", it goes to 1280x800 (1/4 resolution), but DOESN'T use the extra pixels, so it looks horribly blocky.

Anyone have any links to information about what is really going on here? I cannot access the full native resolution of the external monitor (as I could on my MacBook Air using the SAME dual link DVI connection to this SAME monitor), even if I set the MacBook Pro to Scaled->More Space.

Not sure what to do on this.

2560x1600 requires a dual link DVI adapter or display to mini display (my recomendation since its only $10). Otherwise you only get half the vert/horiz data = 1280x800.

Apparently Verxion is already using a dual-link DVI adapter. As previously mentioned, simply hold down option while clicking the "Scaled" option, and the 2560x1600 resolution options will show up.

OSX unfortunately limits the HDMI port to 165MHz - essentially the equivalent of SL DVI. I had a 27" 2560x1440 that can accept that resolution over HDMI. In windows it worked perfectly. If I booted into OSX, it refused to allow 2560. Even with switchresx, I had to make a custom resolution at 40Hz for it to work.

Shame, because it would be nice to drive two 2560 displays while keeping a thunderbolt port free

Really? Thanks for that info.

At home I hooked up the laptop to a 30" 3007WFP via apple's usb-powered displayport to DVI adaptor, and it worked fine at 2560x1600, until I left and came back to find the laptop asleep and/or crashed. I rebooted it, and then found myself having the same problem as the OP.

I resorted to SwitchResX, which managed to successfully set the 3007WFP back to 2560x1600.

RoboTeddy, how did you actually cable up two 30" displays as I'm interested in doing the same? Thanx.

Found this post on an apple thread.

Hope this helps for anyone who is still experiencing problems.

"Update from Applecare: this problem made its way to engineering and they pointed out a 'hidden' way to fix this with no special 3rd party software:

When you bring up the resolutions for a given display, as its set to 'best for display' hold down the 'option' key while clicking 'scaled'. The scaled menu should now show all the resolutions supported by the monitor. On my Dell it shows 2560x1600 and everything works fine when I select that."

I have my Retina Macbook pro hooked up to two Samsung 24" 1920x1080 monitors.

The only issues I have are:

1.) If the computer wakes from sleeping the dual displays don't come back to life at times. Need to be unplugged and plugged back in.

2.) If I shut the computer off and restart from cold, the computer hangs at the white screen with the grey Apple logo. I need to disconnect my external displays anytime I reboot my machine.

I think you aren't supposed to see those options at all, but just the regular screen with a list of resolutions.

Hey, I've got a 2407WFP-HC, too!

Runs fine at 1920x1200 on... ahem... VGA.

Looks like there's some secret key strokes you need to do:
