For the higher resolutions, make sure you set the HDMI Deep Color setting to 4K, which increases the HDMI bandwidth to 48.0 Gb/s. Otherwise, you may not be able to get your screen to display the content, especially at higher frequencies, if you set the same setting to Off.
Furthermore, you should also make sure that you are using a compatible HDMI cable as well as connecting a device that supports the same resolution, horizontal frequency and vertical frequency combinations.
