Hello Awesome1120,
Thank you for reaching the Intel(R) Communities! I understand that you would like to achieve 4k display resolution but the only resolution doable now is 1366x768. We can certainly check this scenario to find a possible solution for that matter!
Please be aware resolution also depends on the monitor's capabilities so it is required to have a 4k monitor or display to achieve the resolution desired.
In order to check that, please create and attach the graphics report from your system.
How can you do the graphics report?
The instructions are here: https://www.intel.com/content/www/us/en/support/graphics-drivers/000005848.html
Please save the report and then attach it to your answer.
Thanks,
Esteban C
