HD4600 integrated graphics - only getting low res output!

[Toobad]

Just put together my Haswell rig this weekend without any major drama but I am astonished to find it won't drive my 2560 x 1600 30" Dell 3007-WFP at any more than 1280 x 800 resolution!

The Asus Z87-Pro motherboard offers the following video connections:

VGA 1920 x 1200 @60Hz
DVI 1920 x 1200 @ 60Hz
HDMI 4096 x 2160 @ 24Hz and 2560 x 1600 @ 60HZ
Displayport 4096 x 2160 @ 24Hz and 3840 x 2160 @ 60Hz

The video cable coming out the Dell is Dual Link DVI so I realised I could not connect to the mobo DVI port and get my native resolution. I bought a Dual Link DVI-to-HDMI adapter (Scan LN45576) but I only get 1280 x 800. When I connect to the DVI port I still only get 1280 x 800!! I am using the latest Intel graphics drivers and Windows 8 recognises the Dell monitor. Any ideas or explanations?

I daresay the easiest solution would be to add a discrete card as even a sub-£30 jobbie will give me 2560 x 1600. Although I'm not an avid gamer I don't mind springing for something a little more exotic like an MSI GTX 650 Ti Boost Twin Frozr (Scan LN50189) as I believe Photoshop will happily use 2Gb of GDDR5 and that card is fairly quiet as well. My be quiet! 480W E9 PSU should handle it OK. Is that sensible?

Are you able to create custom resolutions?

Display port to dual link dvi would probably be a better option than hdmi to dvi (I've found hdmi can do funny things)

But it's very strange you cannot get over 1280x800 on just dvi.

Thanks for the input guys. I think my Dell 3007 is reverting to its "secondary native resolution". It does this when it cannot be fed with a dual- link DVI source and the Asus Z87-Pro is single-link DVI output. I thought it would go to the max 1920 x 1200 but under single link DVI it uses 1280 x 800 which is a quarter of its native 2560 x 1600 resolution.
As for HDMI, I'm sure things would have been fine if the monitor had an HDMI input too but sadly it doesn't and as Pob confirms Dual DVI to HDMI adapters can be a bit flaky. Anyway I came by a cheap Radeon HD7750 today and as that has dual-link DVI out my problem has now been resolved.
