Thank you for your response.
Looking into the report that you have provided I noticed that you are running Windows® 10 on your system. I was looking for graphics driver provided by the manufacturer for Windows® 10, in this case, seems that they don't have any available. See the following link for reference:

For testing purposes you could try generic graphics driver for Intel® HD graphics 4600 controllers following the next steps:
Could you provide me with the graphics report of your system (complete the report with the external display connected to the system), follow the steps to complete the report:
I think the issue could be coming from the HDMI output on your laptop. If the HDMI port on your laptop is revision 1.4 then it is not capable of driving 3840x2160@60hz due to insufficient video bandwidth.
I searched online for the specifications of the Toshiba Satellite P50t-B1393, but I couldn't find anything that confirms if the HDMI port is revision 1.4 or revision 2.0.
Have you checked this with Toshiba? Do you have any manual or datasheet that confirms the revision of the HDMI output?
I was checking your case and would like to know if you were able to verify the HDMI® version on your laptop, or if you have access to the system manuals?
