4k internal display does not work Ice lake

[Sudo User]

My configuration is:

• Dell XPS 13 9300
• Core i7-1065g7 (G7 Iris plus graphics)
• 16 GB RAM
• UHD+ monitor (4k: 3840x2400 Touchscreen)

 

The problem that i am currently experiencing is that the internal display is recognised but for some reason is not functioning the way it should. The internal display becomes partially fragmented after few seconds of not doing anything, Although the internal monitor is not functioning, when i connect an external monitor (with FHD resolution) It becomes fully recognised and functioning. When i connect the external monitor the internal monitor becomes blank. With the external monitor i can confirm that i have acceleration.

 

Here is a log Boot log.

Here is the config.

 

Here is a picture of the fragmentation.

Here is a picture when there is an external monitor connected.
