Review: StarTech USB to HDMI External Dual or Multi Monitor Video Adapter with Audio

HDMI ports on computers can be incredibly useful – the ability to transform your HD TV into a huge monitor has excellent uses from watching movies to playing games on the big screen. Or for work, you can also use HDMI to display presentations on TVs and projectors.

If your laptop or desktop PC doesn’t come with an HDMI-out port then the StarTech USB to HDMI External Dual or Multi Monitor Video Adapter with Audio is very useful, since it effectively transforms a USB port into an HDMI one.

Another benefit is that even if your PC comes with HDMI, you can use this adaptor to extend your desktop over an extra monitor – a worthwhile feature if your graphics card isn’t up to the task.

While some people use a DVI to HDMI cable to connect their PC to a high-definition TV – because DVI ports are far more popular than HDMIs on computers – the DVI can’t handle audio.

The StarTech USB to HDMI External Dual or Multi Monitor Video Adapter with Audio, as the very long-winded name suggests, can handle audio. A small feature perhaps, but it’s very valuable if you use your TV’s speakers when watching media via HDMI.

Verdict

This is a useful product, although if you have a decent graphics card that comes with HDMI and can support multiple monitors then you’re not going to need it.
