Today we’re looking at three video adapters from ICZI. We received these together, tested them together, and now we’re writing a review together. How sweet. Let’s get started!

1. DisplayPort to HDMI adapter

What does it do?

  • Converts a DisplayPort input into an HDMI input
  • Useful for desktops or laptops with DP but no (free) HDMI
  • 3840 x 2160 @ 30Hz, 1920 x 1080 @ 120Hz
  • Only works one-way (DP to HDMI)
  • 30 day free returns, one year warranty

Does it work?

Yup, we connected it to our desktop’s DisplayPort on a GTX 1080 and connected a monitor via HDMI. No configuration was required beyond switching to the HDMI input on our monitor.

As noted above, refresh rates drop above 1080p, so our 1440p / 144Hz monitor was limited to 60Hz. However, this is a limitation of HDMI, so it’s not a strike against the adapter itself.

Should you buy this?

Sure, if you need to connect an HDMI-only display to a DisplayPort, you can get this adapter. If you only need 1080p, you might prefer a cheaper cable that has DisplayPort on one end and HDMI on the other. Finally, there is also an upgraded version of this adapter which can do 4K at 60Hz (but this requires an HDMI 2.0 port on your TV / display).

2. Thunderbolt to HDMI adapter

What does it do?

  • Converts a Mac’s Thunderbolt port into an HDMI port
  • Comes with a free HDMI to HDMI cable
  • Useful for laptops with no free HDMI port
  • 3840 x 2160 @ 30Hz, 1920 x 1080 @ 120Hz
  • Only works one-way (ThunderBolt to HDMI)
  • 30 day free returns, one year warranty

Does it work?

Sure does! We connected the adapter to our MacBook Air’s Lightning port using the provided HDMI cable, and we were able to connect a 1080p display without problems. The adapter feels durable enough, and it is long enough that you can tuck the cable behind the screen.

Should you buy this?

Sure, if you have a laptop with ThunderBolt but no HDMI port then you’ll need an adapter like this one to connect most displays, e.g. TVs, monitors and projectors. The £12 price seems competitive with other adapters on the market, particularly given the inclusion of an HDMI cable.

3. USB-C to DVI adapter

What does it do?

  • Converts a USB-C port into a DVI-DL port
  • Useful for plugging DVI monitors into USB-C laptops and desktops
  • Supports up to 2560 x 1440 @ 60Hz
  • Only works one-way (USB-C to DVI)
  • 30 day free returns, one year warranty

Does it work?

Yup. We connected an old 1440p DVI-only monitor (a Crossover 27Q) to a Dell XPS 15 9560 at 60Hz without any problems. Sadly, we didn’t have an Android smartphone that supports USB-C video out to test as well. The adapter felt pretty well made, and even comes with a little tip to protect the USB-C end from damage.

Should I buy this?

Sure. I don’t think a lot of people will need to, but if you have a USB-C port on your device and a DVI-only monitor to connect, this could be a good choice. DVI supports 1440p better than HDMI, so for 1440p monitors this will be particularly useful.
