Hello,

 

I have a TV LC C9 supporting HDMI 2.1 and is able to display 4k at 120hz.

It works well with my personal desktop with a NVIDIA 3060Ti.

I received a professional laptop, a Precision 7560, with a NVIDIA T1200.

I disabled the Hybrid mode to be able to have the best I can have on the HDMI port, according to this sheet:

Unfortunately, I still cannot display my monitor in 4K 120hz, as you can see in the following screenshot:

 

Do I need to do something else?
