Shuttle DS-61 Video Mode

[twinclouds2004]

I recently bought a Shuttle DS61 and installed an i7-3770 in it. It works very well, cool and quiet. The only issue is the Video output to my Monoplace 27" monitor with 2560x1440 resolution. DS61 has h61 chipset. It can support upto 2560x1600 but have no 2560x1440 mode. I configured custom 2560x1440 resolution using Intel graphics control panel. When turning on, it does not fill full screen. I can configure the custom mode in advance menu but I don't have any idea what should be fill in. The required fields are Front Porch, Back porch, Sync width, Active, Sync polarity, Scan rate, Total and Pixel Clock for both Horizontal and Vertical scans. Can someone experience to give me some hint what I should do? Thanks in advance!

Googling 2560x1440 HD4000 also brought up a few other similar discussions.

Generally speaking motherboards with a 6 series chipset are limited to single-link DVI-D bandwidth for up to two displays. To get the most out of your Ivy Bridge graphics, you will need a 7 series chipset with DisplayPort. The chipset will support up to three monitors (with limitations) while the DisplayPort output will be the one that supports the higher resolution.

Thanks to AFD and Zap for your replies. I eventually made it work by using Intel's HD graphics control panel to set the custom resolution in advanced mode. The parameters that I used are what shown in here. The only parameter I didn't use is "Blanking" because not place to enter in the control panel. Everything worked fine as expected. Hope this information is useful for others as well.
