Hi, Currently looking at the 2019 MacBook Air for productivity purposes, primarily Microsoft Office, web-based apps and video calls. Want a USB-C monitor with power delivery for a tidy single cable connection when using at my desk but struggling on the decision between a 1440p and 4K for a 27" screen. Ideally would like something visually close to the 27" Retina 5K iMac, which suggests going down the 4K route and scaling it to look like 2560 x 1400 to give equivalent desktop real estate. But...I'm hesitating because I don't know how well the MBA will perform running a 4K display with non-integer scaling - anyone doing this already that can share their experiences? Does everything run smoothly or do you get lag/jittering on animations, etc.? The 'default/best for display' 2x scaling (like 1920 x 1080p) makes UI elements too big on a 27" screen. My closest experience is a 2017 MacBook Air running a LG UltraFine 5K display at scaled resolution and this felt sluggish and caused the fan to run most of the time, so makes me wary!
