HD4000 doesn't have DL-DVI

[Skurge]

So, the Twin Turbo on my 6990 is giving me some issues, so I'm using the HD4000 connected to my U2713HM and I'm limited to 1920x1080.

I'm not sure if it's just the board or HD4000 doesn't support Dual Link DVI at all. I would think in this day and age everything would have dual link dvi support. I don't have a display port cable so I can't use that.

Just sayin.

I believe it's pretty much dependent on your motherboard. HD4000 does support higher than 1920x1080, but the motherboard maker has to include an adequate port on the board itself. Case in point the 13 inch macbook pro r (which uses HD4000 w/o discrete graphics) has a 2560x1600 display.

The connectivity is based on what your motherboard has. HD4000 can go up to at least 2560x1600. My board, for example, has HDMI (1080p max) and DisplayPort (2560x1600 max). DVI seems to be fading though.

edit: this is amusing.

Can I get a list of resolutions that my Intel graphics support?
No. A list of resolutions is not available. The resolutions that are selectable on your computer will depend on many factors including but not limited to:

• The chipset or processor in your system
• Which display port you are using
• How your computer manufacturer has configured your computer
• Your display or monitor capabilities
• If your display or monitor is plug and play
• If your display or monitor is in single mode, clone, or extended desktop mode.

Check with your computer and display manufacturers to find out the supported resolutions of the computer and display. If you are using multiple displays in clone or duplicate mode, you can only select a resolution that is supported by all displays.

I've verified this. From the 7 series PCH pdf. As hdmi and dvi are both the same signal, it looks like they just use the lowest common denominator (HDMI).

Each digital port is capable of driving resolutions up to 2560x1600 at 60 Hz through DisplayPort and 1920x1200 at 60 Hz using HDMI or DVI (with reduced blanking).

Well, I guess that settles it, damn, I might have to find a super cheap card to use in the meantime. Display port cables are like Hens teeth here. Pretty crappy design choice though.
