Ask Jack: How can I add two external monitors to my laptop?

Simon's productivity has benefited from adding an external monitor to his Windows laptop. Now he would like to add a second, giving three screens in all

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. His laptop had two HDMI outputs so the setup was simple, but mine only has one. What's the cheapest way for me to do this without changing my laptop? Simon

Any Windows laptop will support two screens - at least, I've never heard of one that won't. Supporting three screens can be just as easy, or much trickier. It depends on the laptop, the graphics card (or integrated graphics), the graphics drivers, and perhaps the amount of memory available. There's no easy way to tell in advance. 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.
