Hello ArnieElkins, thanks for contacting us through the Intel Communities.
Based on the information provided, these are the maximum Display Resolution supported by the HD44000 Quick Reference Guide to 4th Generation Intel® Core™ Processor Graphics (formerly codenamed Haswell) | Intel® Developer …
The graphics controller in your computer supports higher resolutions than the one you are trying to achieve. As an example, it can go up to 2560x 1440 when using Display port but this depends on the monitor supported resolutions and the limitations set by the computer manufacturer.
I recommend you to please get in touch with your system manufacture or try the graphics drivers provided by them.
Apparently Intel does not support dual-link DVI. I found a computer with a previous generation of the Intel video, but with a DisplayPort connector, and when I plugged it in, it worked perfectly with the monitor. I saw a message somewhere indicating that Intel does not support dual-link DVI in their video chipsets. There seem to be an awful lot of monitors coming out that require dual-link to reach their maximum resolution. It is sad that I cannot use the built-in video card with any of those. Since this computer was not equipped with a DisplayPort, and my monitor supports only very specific resolution/refresh combinations, the only workable solution for that machine is a new video card.
