Thank you everyone, you guys really help me a lot. @Froody129 any brand you would recommend as I only know 3 brands which is Asus, Acer, Alienware have Ultrawide and nice colour.
I am going to get a new monitor and I am stuck between Ultrawide and 144hz 1440P monitor. Do 100hz and 144hz differ that much if i am gaming? I am looking at Asus PG348Q and Asus PG279Q, I have 6700K and 1070 in my rig now.
