Most iPad models support AirPlay - and/or connection to a single external monitor using an appropriate HDMI Adapter. The most recent models of iPad Pro also support HDMI Alternate Mode/DisplayPort connections over USB-C. Compatible iPad models can be connected to a single monitor/TV.
You should note, however, that iPad does not support an extended-desktop view that has different views on a connected monitor - but instead permits the iPad display to be “mirrored” to a compatible external monitor/TV, preserving the iPad’s screen aspect-ratio.
An iPad can also “stream” media content directly to an attached monitor. Only when displaying video content can the connected monitor display different content.
