So right now I was thinking of buying an ASUS rog STRIX G17 with Ryzen7 6800HS and RTX3050 4G. I choose this model because this device has one HDMI one USB type with display port and power delivery and a USB-C 3.2 Gent 2 port my question is can i run 4 monitors with this device all monitor are 2K monitors!
Not natively by the laptop. You will get two outputs HDMI and with a USB C to Display Port adapter cable. You can get an external USB dock that would have dual displays but that will run off the much slower video chip inside that dock. For multi monitor setups, with gaming laptops, really best you would get is a single external monitor and the laptop screen.
