is just like any other camcorder...
If you need to monitor the video only, then use the AV cable connected to a monitor with the yellow composite video output.
There are specially made "monitors" that can be camera mounted. If camera-mounting is not a requirement, then the monior size/weight is not an issue - any LCD panel or CRT TV works. When I use a camera crane, I use a Sony 8.5" portable DVD player with the "Input" switch selected.
(There are other camera mount - or not - monitors that can use composite or HDMI connections for high definition camcorders.)
Just wondering anyone know of an external screen available for the Sony DCR VX1000e that can be used while recording ??
