I have a Dell 3000WFP monitor with native resolution 2560x1600@60HZ (latest Dell driver /.inf file installed)
This monitor is being driven by an ASUS Z87-A motherboard with integrated HD4600 graphics adapter (latest motherboard BIOS)
I am running Windows 8.1x64, latest automatic updates
Whether by HDMI 1.4a cable or DVI-D cable (the only two options available), the maximum resolution the intel driver recognizes is a disappointing 1920x1200
I can plug the same monitor into my Nvidia GTX780 and get full native resolution via same DVI-D cable. I need this GPU not to be driving my display however, as I need all it's processing cycles for CUDA calculations
I have seen reference to adding custom resolutions to the Intel driver, but there seems to be no way to do this in reality.
The custommodeapp.exe file supplied with latest Intel HD4600 driver does nothing when clicked, even using administrator privileges. I note this file is not installed into windows/system32/drivers/Graphics as one member suggested in another thread, There is not even a 'Graphics' subdirectory created in 'Drivers' by the installer, and using windows search function reveals the only instance of the custommodeapp.exe remains within the folder containing the supplied installer itself - and this doesn't appear to work anyway..
Can anyone please tell me how can I add 2560x1600 resolution, given the above?
