I've got a ~3 year old Shimian 1440p. It only has a DL-DVI output on it. I am currently without a video card. I just tried using a DVI-HDMI cable on the iGPU (i7-6700k CPU) and did not achieve a signal (I reset my motherboard CMOS just make sure the iGPU wasn't disabled).

I know when I bought this monitor it was advertised as not being able to work with integrated graphics, but would a Will a DL-DVI to display port adapter work?

Thanks in advance.
 
you're problem is that unless you get a active adapter you won't be able to get the dual link DVI signal your monitor needs.

If your monitor really has only a dual link DVI input then you will need to give it such a signal somehow. No passive (unpowered) adapter will give you more than single link DVI, which can handle only upto 1920x1200.

if you aren't getting a new card soon, or are getting one that doesn't have a dual link DVI output (which is getting hard to find) you'll need a active converter such as http://www.accellcables.com/product...ink-adapter-with-3d-support?variant=729675125 or http://www.dell.com/en-us/shop/accessories/apd/470-aanw?c=us&l=en&s=dhs&cs=19&sku=470-AANW but they aren't cheap.
 
one last thing I forgot. No active adapter that I've found does mote than 85hz at 1440. So if you display is a high frequency one you either need to replace it or ensure you get a card that has a dual link DVI built into the card.
 
That explains why it wouldn't work with my 2012 Yamakasi Catleap Q270 LED (have the same CPU as the OP) and using a dual-link DVI to HDMI adapter wouldn't work with my Gigabyte P34Wv4's HDMI port.
 
You can get this combination to work by adding the hdmi extension block in the edid. The default edid does not provide such a block, so the computer assumes that the display should use the 165MHz pixelclock crossover point. Because only one res is supported, and the port can't do it, the output will be disabled. By adding the extension block, the system will ignore the crossover point and allow 1440p60 through one link, which usually works.

You will need to disable the write protect on the monitor's eeprom and use linux to flash the new edid (search edid-rw or rw-edid).

Here is an example edid that I made for my dad's qnix 1440p to connect to the intergrated intel graphics on a lenovo y50p laptop.
