Asus PB278Q resolution problem on mac mini 2012

To get 2560 x 1400 you need to remove everything HDMI from the connection

and use a > Mini DisplayPort to DVI Adapter with a good DVI-D cable,

or a straight > Mini DisplayPort to DisplayPort Cable connection.

hello,

I have exactly the same problem.

mac mini 'late 2012' and pb278q

I tried also with mini displayport to DVI adapter and dvi cable...

max resolution always 1920x1080

are your problem solved?

any idea?

thanks

Hello, with that high of rez you need the dual-link DVI adapter, 1920/1200 is max that Single-link DVI can do...

@michmuch:

Did the MDP to DP solution work for you? I also have a Mac Mini (2012)/PB278Q combo...bought a minidisplayport to displayport cable at a local computer store and can't get it to work.....the monitor says "No Displayport Cable attached".....not sure if the problem is with the cable or the monitor....just wondering what others experiences have been like?

Yes, for me it works perfecty.

I have a mac mini late 2012 with osx 10.8.4

I bought this cable

https://www.distrelec.ch/c%C3%A2ble-mini-displayport-fiche-displayport-fiche-1-8 -m/maxxtro/pb-958-06/849455/informatique/fr

it seems the same as yours...

I never seen this message "No Displayport Cable attached" !!!

when I start mac mini and screen, I could see for 1 second a message "display port no signal"

after that second, I have the apple logo and the max resolution.

In the "préférences système"->"moniteur" the title is ASUS PB278

Résolution is "Optimisé pour l'écran"

Rotation is Standard

Tx rafraichissement is 60 Hertz (NTSC)

if I click on 'A l'échelle' I could see that the resolution is 2560x1440

may be there is a problem with this cable ???

I tried it with a Mini Displayport to Displayport cable. My Macbook Air crashed! Also the mac crashed with a Dr. Bott adapter from MiniDisplay to Display.

Apparently the quality of cable you use matters. I originally used this one (ngear):

http://www.ncix.com/products/?sku=74605&vpn=NG%2DDPMDP6&manufacture=nGear%20Tech nologies%20Inc%2E

And it didn't work. I returned it to the store and ordered this one (StarTech):

And it's working great on my Mac Mini 2012. The resolution is amazing. I'm now finally happy with the monitor!

Thanks to this thread I bough the $99.00 dual port DVI adaptor and everthing works fine with a MacBookPro (2012 non retina display) and a and ASUS 2560xl440 monitor. I'm getting the marvelous 2560x1440 resolution with absolutely no problem. The mini display to DVI adaptor will not do the job since the ASUS display requires the dual port pins and the extra usb cable to do the job. Thanks to all.

Of course not, you can pay $69.00 or perhaps less. See, http://www.monoprice.com/products/product.asp?c_id=104&cp_id=10428&cs_id=1042802 &p_id=6904&seq=1&format=2 Or, in the alternative, you can buy an Apple display for $999.00 which is more $280.00 more than the ASUS PB278Q.

Got the mini display port to display port cable per den.thed's recommendation and it worked like a charm.
