Steps to try to access missing resolution settings in the Intel Graphics Control Panel. Depending on the HDMI* revision, a resolution and refresh rate may not be available.
How can I set 3440x1440 resolution on an external monitor using the Intel® Graphics Control Panel in Windows® 10.
The selectable resolutions on your computer depend on both the computer configuration and the resolutions supported by the monitor or display. To resolve this issue, follow these suggestions:
- Install the latest graphics driver
- Install the latest .INF
- Install the latest BIOS.
If the resolution in question is not a selectable resolution after following the steps provided above, then the cause of the issue is a hardware limitation. Depending on the HDMI* revision, a resolution and refresh rate may not be available. HDMI* revision 1.4, 1.4a,1.4b is limited to 4K x 2K @ 24Hz.
