Hi [NAME] Dell Support for Alienware 25 Gaming Monitor AW2521HFA Documentation includes How to Connect a Monitor to a Dell Computer | Dell UK This is the Alienware Laptop forum and this thread should be moved to the Dell G forum to get specific Dell G5 15 5500 gaming assistance. G Laptops (Inspirons) are not Alienware Laptops - Dell Community   [NAME]-Cares [NAME]-Chris M 
Please advise which connection to choose for the G5 15 5500 NVIDIA GeForce RTX 2070 with Max-Q design notebook on the Dell AW2521HFA monitor. I have Hdmi 2.0, mini display port 1.4 and usb C there. So I don't know what would be most suitable for playing games? Thank you in advance.
