One example is the Plugable UGA USB 2.0 to DVI/VGA/HDMI Adaptor, which costs £37.95. I expect you will need an adaptor that includes an external graphics card. From a position of ignorance, I looked for better-known brands such as Plugable, Kensington and Climax Digital, but readers with experience of multi-monitor laptops are welcome to suggest alternatives below. Amazon searches find lots of examples, none of which I’ve ever used. If your laptop only has one video port, you can use a USB display adaptor instead. These are usually used to “clone” screens, but Windows should be able to set up an extended desktop that bridges two or more screens. The two screens may have slightly different colour renderings, or other differences (brightness, contrast etc), which could be annoying.Īlternatively, if your laptop has a DisplayPort or Mini DisplayPort, you can buy a splitter or multi-monitor hub that will drive two or three screens. This is not quite as good as using two HDMI ports because HDMI and VGA are different video standards. For example, you could plug one into an HDMI port and the second into a VGA port. Some laptops will support two external monitors if you can find a way of plugging them in. However, if you search online for your exact laptop, you may find that someone has already tried it, and this is probably the best guidance you can get.
It depends on the laptop, the graphics card (or integrated graphics), the graphics drivers, and perhaps the amount of memory available. Supporting three screens can be just as easy, or much trickier. What’s the cheapest way for me to do this without changing my laptop? SimonĪny Windows laptop will support two screens – at least, I’ve never heard of one that won’t. His laptop had two HDMI outputs so the setup was simple, but mine only has one. I have recently found that adding an external screen to my work laptop has really helped with productivity, but having visited a colleague who had two additional monitors, I now want that too.
