As business laptops, ThinkPads aren’t necessarily known for having the sharpest, most colorful displays. That said, modern ThinkPads are starting to feature OLED displays that are significantly richer and more vibrant than their IPS predecessors.
If you plan to stream content, play games, or work with color-specific tasks, it’s worth springing for a higher-res OLED display. For everyone else, I’d recommend not settling for anything less than 1080p resolution and a 60Hz refresh rate.
