mac mini with Dell u2713HM, not getting full resolution.

HI, i recently bought mac mini late 2012 ed, connected with dell U2713 monitor via mini display to vga adapter. i was expecting to get 2560x1440 resolution but i get 2048x1152. i use this system for medical imaging so can any one help to suggest any solution so that i get required resolution.

My first thought is the VGA connection. VGA is a very old display pathway...and may not support all resolutions that the Mac-Mini/Dell U2713 combo are capable of.

From the specs I found...this monitor is supposed to have the following video ports:

- DVI-D
- HDMI
- Displayport
- VGA

Of these 4 port types...VGA is probably the worst one to use. Any one of the other video ports will probably provide you with more success.

thanks for reply. theoretically, i totally agree but believe me with VGA adaptor i get better resolution. i tried DVI-D and HDMI as well but didnt get expected results. i havent used mini dispaly to display port adapter as i dont know whether its available or not. so in the end problem is not yet solved.

And if you continue to use the VGA port on the monitor...the problem may never be solved...since the VGA pathway may not support the 2560x1440 resolution of this monitor.

The 2560x1440 resolution of this monitor is it's "native resolution"...which means that's the optimal resolution for picture & text quality.

If you want native resolution, you're going to need to get the correct cables.

HDMI max resolution is 1920x1080 (reckon it can do 1920x1200 on a 16X10 display)
DVI-D max resolution is 1920x1200 (technically, but sometimes can get higher - rare, but not to match that monitor)
VGA max resolution is about where you are at.

To get the monitor's native resolution, you're going to need either a displayport or a dual link DVI.

With your late 2012 Mac mini, you would need a 'mini displayport' to 'displayport' cable.
If Amazon is making that in their Amazon basics, have found their cables to be pretty good at a good price.
There is also monoprice.com.

Thank you Bobtomay, i ve found minidisplay to display port cable on amazone. will give you feed back when its available to me.

That should do the trick to get you up to native resolution - I went and checked Amazon after I posted and they didn't have it in their basics line and didn't really know anything about the manufacturers I saw to make a specific recommendation for you.

DEAR BOBTOMAY, following is a link where required cable is available. do think its the one ?

Amazon.com: StarTech 6-Feet Mini DisplayPort to DisplayPort Adapter Cable - M/M (MDP2DPMM6): Electronics

hi, i just got minidisplay to display port cable and it solved my issue, now i am getting full 2560x1440 resolution. thank you all for tips
