sandybridge and 2560x1440

There was a thread at some hardware site I read a while ago about running SB graphics at greater than 1920x1080 resolutions (I can't seem to find that thread). Anyway, the problem was that the HDMI on the MB's didn't support higher than 1920x1080, even thought the latest version of HDMI (1.4) supposedly can actually support higher resolutions up to 2560x1600. So, if the MB didn't have a DisplayPort you were stuck at a max of 1920x1080.

If you want to use HDMI at over 1920 you will need to check the MB manual to see if it supports those resolutions. Otherwise, make sure the MB has a DisplayPort to run up to the higher resolutions like 2560x1600.

If the MB has a DVI port built-in (and it is in most motherboards), OP can hook the PC to the monitor (via a dual-link DVI cable) and not worry about any 1920 resolution cap.
 
It is all down to the display port. HDMI and DVI both top off at 1920 x 1080. With the Display port you can reach up to 2560 x 1600. This is stated on the earlier link Anosh but also you can see it listed on the TPM for the Intel® Desktop board DH67BL on page 21.

DisplayPort’s maximum supported display resolution is 2560 x 1600 at 60 Hz refresh
with a 16:10 aspect ratio (WQXGA). DisplayPort 1.1 adds support for High Bandwidth
Digital Content Protection (HDCP) version 1.3. HDCP support enables viewing of
protected content from Blu-ray Disc* and HD-DVD optical media over DisplayPort 1.1​
connections.

Thank you for the answers.

I was thinking of running two monitors with one 2560x1440 through the displayport and another 1920x1080 through the HDMI concurrently with a i5 s2405 on an Intel DH67CF-B3.

Judging from the manual (p16):
http://downloadmirror.intel.com/19486/eng/DH67CF_ProductGuide01_English.pdf

It should be possible:
"If you are using a processor with integrated graphics, the board will support only two
of the three integrated graphics interfaces simultaneously: HDMI, DisplayPort, DVI-I.
Also, during the Power-On Self-Test (POST), the board will not output to the
DisplayPort if DVI-I is used concurrently with DisplayPort. "
