说明：  某些显卡驱动中不支持屏幕旋转的型号的机器，有什么软件可以旋转屏幕90度呢，以前有 PowerStrip 不过是收费的共享软件，有免费的可以达到这种效果的软件吗？ 在 Group 中 Kai 提到了 iRotate 这款小软件，支持驱动多，适应性挺强，效果不错。 安装后，Ctrl + Alt + 上下左右 就可以快速旋转屏幕了。
(Some of the graphics driver does not support screen rotation model of the machine, what software can do 90-degree rotating screen, before charges are PowerStrip is shareware, however, there is free software can achieve this effect you? Mentioned in the Group of Kai iRotate this small software, support multi-drive, adaptability very strong, good results. After installation, Ctrl+ Alt+ up and down so you can quickly rotate the screen up.)
