Nope, didn't bother with the OLED screen on the X1. My current Carbon X1 (9th gen) has a 1920x1200 IPS screen. The M14 has a 1920x1080 screen, so a little shallower. The difference is only mildly annoying, as I tend to keep the same windows in the two screens - email and word processor (WordPerfect, cos I be Old Skool) on the laptop, web browser and pdf reader on the M14. Switching between the two requires the minimize/maximize shuffle, but it's no great hardship.
