Can a monitor switch input based on input?
Yes, you are looking for a device called a KVM switch. This switches input and USB controls quickly via a switch. If your monitor has multiple inputs and you don't need a USB switch, you can just hook both up to the monitor and switch between them using the monitor’s OSD. 4.2K views View upvotes Related Answer Hidenori Inagaki
Is a monitor an output device?
A standard output device is the computer monitor, which displays text, images, and user interface elements by lighting up thousands of pixels with different colors. A computer monitor with a calculator program displayed. The calculator shows that 2 + 2 = 4. There are many other ways a computer could output data.
Is the PC or the monitor output?

Why is a monitor output?
A computer monitor Is not an input device, it is actually an output device. A computer monitor is an output device because your computer sends information to it rather than receiving information from it. As you can see from the diagram below a computer processor sends instructions and data to an output device.
What is a monitor answer?

What is output device?
An output device allows data to be transmitted by the computer in a human-friendly form, for example, sound being played through a speaker. Monitor - The main output device of a computer. It forms images by converting electrical energy into light in the form of tiny dots on the screen called pixels.
What is output in computer?
An output is data that a computer sends. Computers only work with digital information. Any input that a computer receives must be digitised. Often data has to be converted back to an analogue format when it's output, for example the sound from a computer's speakers.
Which device is both input and output?
Devices that are both inputs and outputs include: Network cards. Touchscreens – the display is the output the touch is the input. Sound/audio cards.
Is a monitor an input device?
A computer monitor Is not an input device, it is actually an output device. A computer monitor is an output device because your computer sends information to it rather than receiving information from it.
Why a monitor is an output device

Is a touchscreen monitor an input or output device?
A touchscreen monitor is both an input device and an output device. The touch element of the monitor is the input and the display element of the monitor is the output. Touchscreen monitors are becoming increasingly popular and the market is set to be worth $100 billion by 2027.
Can a monitor be used as an input device?
A typical LCD or CRT monitor cannot be used as an input device. However, a touchscreen monitor can be used as an input and an output device. A standard computer monitor does not have a touch or input layer to act as an input device, therefore it can only ever be used as an output device.
Conclusion
A monitor is an output device because it typically only ever receives data from your computer and then outputs it. Unlike input devices which send data to your computer’s process to be decoded and sent to other parts of the system.
What is an input/output device?
An input/output device, often known as an IO device, is any hardware that allows a human operator or other systems to interface with a computer. Input/output devices, as the name implies, are capable of delivering data (output) to and receiving data from a computer (input).#N#An input/output (I/O) device is a piece of hardware that can take, output, or process data. It receives data as input and provides it to a computer, as well as sends computer data to storage media as a storage output.
What is a monitor?
Monitor. Monitors, also known as Visual Display Units (VDUs), are a computer’s primary output device. It creates images by arranging small dots, known as pixels, in a rectangular pattern. The amount of pixels determines the image’s sharpness.
What is scanner on a computer?
A scanner is an input device that functions similarly to a photocopier. It’s employed when there’s information on paper that needs to be transferred to the computer’s hard disc for subsequent manipulation. Scanner collects images from the source and converts them to a digital format that may be saved on a disc.
What is a joystick?
