USB Monitor
Before I ramble on about USB monitors in this article, I would first like to ask you whether you know about USB ports.
The USB port was like a port which was created so as to allow a common port to draw power from computers.
Previously, different ports existed on the computer, such as the serial port or PS2 port for computer mouse and also the parallel port for printers.
It was only after the introduction of the USB port that these ports were taken away.
The USB port allows other computer peripherals such as computer mice, printers and even other external devices to be plugged into the computer, facilitating data transfer.
It would not take long for companies to discover more and more uses for the USB port, like what I will illustrate for the case of USB monitors.
With the introduction of the USB port, nowadays monitor manufacturers have another source of power that can be tapped to power up USB monitors.
But then I guess the USB port still cannot supply large amounts of power, if not all monitors would have been converted to take up power via USB ports by now.
If you remember in the olden days, the computer CPU supplied the power to the monitor through the PSU or power supply unit.
There would be one outlet and one inlet into the PSU, the outlet is for the monitor while the inlet is for the power from the supply mains.
Subsequently, the PSU would only draw power from the power mains but not supply power to the monitor.
The monitor would have its own power supply cable and be plugged into the mains.
This shift came about as computers became more power hungry, and with its components especially the graphics card consuming more power, the PSU would only be able to supply power to the computer and not to the monitor.
Hence the monitor eventually had to find it own power source.
Yet if you need a smaller monitor, and this monitor would not draw large amounts of energy, a USB monitor would be a good buy.
Normal computers do not contain more than one outlet for the video connection, hence most computers and graphics card only allow one monitor to be connected at the same time.
Think that there are some adaptors that can split the video output into two, hence allowing two monitors.
These may work if you really need two big monitors, but if you ask me I am sticking with USB monitors!
