StarTech.com TB32HD24K60 Thunderbolt 3 to Dual HDMI Adapter 4K 60Hz Mac & Windows Compatible USB C Adapter Silver

works as advertised.

Works perfectly under Linux (Ubuntu 17.10) on a Dell XPS-13-9360. Unlike the 30Hz version of this which worked for a period of time and then seems to cut off one, alternate between them, or both - I guess because it was overheating(?) - this one seems to run very smoothly. I've been using it for a day and a half already and no problems at all. I had been forced to use Windows in order to use my Dell DisplayLink dock (since DisplayLink doesn't work under Linux very well at all, if at all), but now I can stick to Linux - I've not even bothered to try this on Windows because it has been rock solid. Startech don't support Linux, but it works very well indeed - I guess they don't due to a matter of support personnel/training, rather than the device itself.BTW, even though I am using Linux, my config is dual boot, so I can test on Windows too; so I they did support me for the 30Hz version (it had the same behaviour on Windows) - and they give really good customer support.FWIW: xrandr outputScreen 0: minimum 320 x 200, current 6016 x 1440, maximum 8192 x 8192XWAYLAND0 connected 1536x864+1920+0 (normal left inverted right x axis y axis) 290mm x 170mm 1536x864 59.80*+XWAYLAND1 connected 2560x1440+3456+0 (normal left inverted right x axis y axis) 600mm x 340mm 2560x1440 59.91*+XWAYLAND2 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 500mm x 310mm 1920x1200 59.88*+

This is an excellent device that works perfectly with Linux despite the "Windows Only" description. I use it to connect a work laptop running Ubuntu (20.04) to dual 4K 60Hz monitors and it worked straight away with no set-up or configuration needed.I bought this to solve an annoying problem I had with Startech's other very similar looking TB3 monitor adapter, the one with dual HDMI ports at 4K 60Hz. I was using that one before, but it suffered from washed-out colours on the monitors, which I discovered is a known (and still unresolved) problem with Intel integrated graphics and TB3 monitor adapters that use HDMI.As soon as I plugged this in instead I could tell the colours were fixed, and it's been running every day for the last few weeks without trouble. So if you're on Linux and want to connect a TB3 device to dual 4k 60Hz monitors, I'd highly recommend picking this up (it's far smaller and cheaper than an external GPU), even if that means buying displayport to HDMI adapters, as it'll work without any hassle and won't suffer from any colour issues. It also runs cooler than the HDMI equivalent and is even a bit smaller in size.

I used this item to connect two Dell U2417H monitors to a Dell XPS 15 9550 laptop. To do this I bought two HDMI - HDMI 1 mtr cables from Wilko at £2 each, and made all three screens work independently by interfacing them with this StarTech.com Thunderbolt 3 to Dual HDMI Adapter - 4K 30Hz - (Windows Only Compatible). I'm running with Windows 10 and it was "plug and play". (My system is not 4K, but the adapter works anyway). All three screens appeared in "Display Manager", and were simple to configure. Only one problem on setting up, the system was silent, when I added the adapter it diverted the sound from the laptop speakers to the non existent speakers in the monitors, knowing that, it was a simple task to reverse the process and set the laptop speakers as the default. The Adapter works hard and gets warm, this is to be expected, it's not too hot to handle. The lead from the Adapter to the Thunderbolt port is 12 inches long; I would prefer longer, but it's not a problem. The Startech help desk was fast, knowledgeable and helpful. Update: Its now 26 June 2018, and I have experienced no problems with the above set up running 8-12 hours a day/365.

I have been looking for a while at how to create a duo independant display setup to use with my macbook air 2018 (OS Catalina). I also have 2 Hanns-G 24" screens. Just plug in play around with your screen arrangement, no need to download any drivers either. Works perfectly. No lag between the screens either. I just have to say thank you to the tech people at StarTech.com who guided me through through to which product would be suitable. The price was pretty amazing too. Got it on here for £87.30 RRP £165.59. StarTech website doesnt do it that cheap, but the tech people are amazing.

Correction, this doesn't work well with the larger monitors, and I have to wonder about the long term reliability with the two Dells (I've not tried them yet). The issue is that this is designed to run at 30Hz, and the monitors are at 60Hz. It works for a while, sometimes even a long while, but eventually it becomes unreliable - I presume it is overheating or something like that. There is an identical looking 60Hz model of this, so I advise getting that; and that is what I am going to get (not tested it yet) - as an addition, it claims to support Apple computers, so there is even more certainty that it will support Linux (though this one seemed to too - so long as you're driving 30Hz monitors).
