Hello,
today I got a beautiful acer nitro 5 (AN515-55) directly from amazon.es, but I have a little problem / doubt: according to the specifications the monitor of this notebook should be at 144hz but, I don't know why it tells me that its max refresh rate is 60. Checking better in the windows settings, I noticed that the monitor is connected to the integrated cpu (it's an i7 10750h), instead of the gtx 1660ti.
I would like to know if it was possible to change this "connection" or if, if not, at least to raise the hz of the monitor, as per specifications, keeping the intel gpu.
(I have already put the preferred gpu the gtx from the nvdia panel but nothing)

tnx
