I've been using a Matebook X Pro (from Huawei) for the past three years and I have to agree: a 3:2 ratio (at 3000x2000 resolution) is amazing. I've been slowly looking around for a newer machine for work, but honestly most screens suck in comparison.

The HP Spectre x360 14 may be what you’re looking for - it has a 3:2 aspect ratio and options for both an OLED screen (better color, worse battery life) or regular LCD screen (built in electronic privacy filter, better battery life).

I've been pondering getting the 15 inch Spectre, I just can't get over the weird placement of the touchpad and the keyboard including a numeric pad. I know it's silly, but it's just... why make something so pretty then make it asymmetric? It's bizarre.
