How to display a notebook with a projector

How to connect a laptop to a projector:

ThinkPad t61:

One method:

1. Right-click the desktop and choose NVIDIA control panel.

2. select Advanced Settings

3. Select the same (replication mode) on the two monitors)

4. Select the monitor you want to use ----- select the projector in front and the notebook in the rear (the reason is that the projector resolution is lower than the notebook, and the notebook adapts to the projector)

Another method is:

FN + F7 (Press and hold FN, and then press F7 to see the screen change. Generally, press 3 to adjust it) (Note: the shortcut keys for each brand are different, thinkPad uses F7 to change the screen). This method cannot be implemented when the driver, video card, and shortcuts are not properly installed.
