Can I connect my smartphone running Android 4.2.2 to a spare dell lcd monitor by using a mini usb cable so I can mirror the android screen onto the monitor? Is it possible? Using some app maybe? No desktop is involved. Just a spare lcd.
Original answer from September 2015: No, you cannot with a standard USB cable. Depending on the mobile device in question as well as the monitor, you could possibly connect the phone with an MHL adapter.
Update September 2020: Five years later and, of course, there are greater options for connecting a mobile device to an external screen. Hoping that everyone is now running newer than Android 4.2.2. and with the use of USB-C for connections, I've been using this USB-C to HDMI with OTG USB-A and USB-C charging. The important part is the charging feature for two reasons:
Some devices will not transmit video without additional power.
The adapter will charge the device while it is being used to drive an external screen.
