Monitor: HP ZR30w
Motherboard: Gigabyte H87N-WIFI
CPU: an i3-4330 having Intel HD Graphics 4600
No separate GPU
The monitor has DVI and DP inputs. The motherboard has DVI and HDMI outputs. The native resolution of the monitor is 2560x1600. I first tried connecting DVI and saw that the max resolution I could use was 1280x800. I tried the bios and driver updates Gigabyte provides for the board, ran Intel's driver scan and update program, and installed HP's "driver" for the monitor. Both Windows and the Intel graphics settings app still max out at 1280x800. I thought maybe it's a limitation of DVI so I used a HDMI to DP adapter (StarTech HD2DP, a powered adapter that claims 4K capability) but it too only goes up to 1280x800.
I read that you can use CustomModeApp to force an arbitrary resolution. I found this program on my computer but when I launch it, the Select Display menu is empty -- no displays are listed at all. If I start to type a number in either custom resolution field, it crashes.
I found a way to get to a Custom Resolution tab of the Intel graphics control panel and the display is available, but trying to add 2560x1600@60 I get the error "the custom resolution exceeds the maximum bandwidth capacity". I can add 2560x1600@30 but trying to actually switch to it in the general tab always fails, I just get a black screen for a few seconds and then I'm back to 1280x800.
Is there any way I can drive this monitor at 2560x1600 with this particular computer? If not, what part of my setup is the problem?
