If you can live with a merely fine screen instead of a show-off OLED or 4K display, it's hard to fault HP's EliteBook 840 G9. This business laptop includes everything from 5G mobile broadband to a high-res, AI-enhanced conferencing camera, along with highly competitive performance and additional security. The only question in our minds is how HP can top it with the would-be EliteBook 1000 series, and whether it can earn our Editors' Choice award next time.

大体上，这个屏幕尺寸常见于亚笔记本电脑，超极本和变形本中。对这三类产品来说这个尺寸都较大。亚笔记本中尺寸最大的机型是采用这个屏幕尺寸。
