Pros
Cons
惠普ProBook 440 G4非常类似于它的兄弟姐妹，其中包括优缺点。它是一个入门级的商用设备，所以你必须忍受一些妥协。 这包括一些功能的缺失，如SmartCard读卡器或对接端口。在外壳质量和端口种类上，ProBook也落后于更昂贵的产品，例如惠普自家的EliteBooks。
然而，ProBook 440 G4的最大的问题是屏幕。我们的测试机已经配备了你所能获得的这个机型的“最好”屏幕，但我们仍然感到失望。我们不明白为什么惠普甚至不提供IPS面板作为选择。在过去，我们也评测了更好的TN面板。
惠普 ProBook 440 G4速度快，提供良好机身和舒适键盘，但显示器难以匹配超过1000欧元（约1074美元）的价格。
更新后的ProBook 440 G4的性能并不令人失望，益于快速处理器和固态硬盘，系统可以处理许多应用程序。另一个问题是：是否可以从专用的图形处理器中获益。它显然比集成显卡更强大，但这是主要体现在你玩游戏时。如果你想节省一些钱，你一定可以选择一个有酷睿 i5和集成显卡的产品。由于令人失望的显示效果，我们仍然很难推荐的14英寸版本的ProBook给所有用户。
