external high refresh rate
Hello Dell Community,
I’m considering using an external high refresh rate monitor with my
Dell Precision 7560 (i7-11800H, RTX A3000, Optimus / no MUX).
According to the architecture, all display outputs go through the Intel iGPU (DP 1.4).
I would like to confirm:
1) Can the Precision 7560 output more than 60Hz (e.g. 144Hz or higher)
via USB-C / Thunderbolt to DisplayPort?
2) Are there any firmware, BIOS, or Dell-specific limitations
that cap the refresh rate on external monitors?
3) Has Dell validated or tested any high-refresh-rate external displays
on this model or the same 2021 Precision generation?
Thank you.

@ejn63 i see some information that intel tiger lake H on i7 11th can output high frame rate, on Intel specs they only show the maxium resolution, if i use fhd, can it possible
If so, ask the source you've seen for verification, There are no doubt gaming notebooks with the CPU that can do high refresh but those have a MUX that allows direct video output from the discrete CPU. That bypasses the GPU limitations of the CPU.

1. No.
2. Yes, the GPU on that CPU can only do 60 Hz refresh.
3. No; no need - the GPU doesn't support high refresh.
Intel specs (see the GPU section)
