Hi I have tried all the various settings I can think of and created custom resolutions but I have been unable to achieve a resolution higher than 2560x1440 (44p Hz) on my Dell P2415Q monitor. I am using HDMI so I know it can't go above 3840x2160 (30p Hz) but whenever I create that resolution it comes back as not enough bandwidth available. Here's the report from my Intel HD Graphics Control Panel - System Information. Any assistance would be greatly appreciated.
