I have an HP ZR2740w monitor that uses either DisplayPort or Dual-Link DVI and runs at either 1280x720 at 60HZ, or 2560x1440 at 60Hz. On my old computer with an Nvidia card, I was able to use the Dual-Link DVI to run at 2560x1440. I have an HP laptop with a Displayport connector, and it runs the display at full resolution as well. However, I just picked up an HP Pavilion 500-223W, which uses the Intel HD 4600 with its i3 processor, and does not have a Displayport connector. Using the DVI port, I can only get 1280x720, despite using the same cable as on the old computer. It seems that there is a driver issue somewhere. In the driver software there is an option to list all modes, and it shows both modes as being available. However, when I go to set the resolution, only 1280x720 is listed. If I attempt to set a custom resolution, I get the error that the resolution specified 'exceeds the available bandwidth'.
This has been a problem in the past for both NVidia and ATI, and both companies now have drivers that fully support the monitor. Where can I find a driver that will display correctly on this monitor? I have the problem in Windows 7 Home 64-bit, Windows 8.1, and Xubuntu linux 14.04.
In Xubuntu, this is what I show for a driver:

It comes from this file:
In Windows, I am running the latest BETA driver:
Is there a fix for this that will allow the Intel HD 4400 in the latest i3 to run the ZR2740W all full resolution? NVidia and ATI had problem initially, but they figured it out and fixed their drivers. Do I have to buy a new video card?
