After reading all the mixed reviews, I was a little hesitant to buy it but am so glad I did. I have a 8 year old Dell XPS8400 with an intel I7 processor, a very nice rig in its day but stuck with PCI-@ 2 video cards. I hated to buy a new computer as this one is still perfectly good and super fast with an added SSD. But I needed to drive both a 30" dell 3400 X 2400 monitor and a new 4K monitor. No way the old video card was up to it, limited to 1900x 1200 dpi on the 4K monitor. So this was the only real choice it seems. Downloaded the drivers, installed with no issues and plugged in the 4K monitor and instant success. It is a flawless picture and even does HD videos pretty darn well, better than expected. The mouse is a bit laggy so have to move it more deliberately but nothing terrible. I did a before and after processor load test and on a dedicated USB3.0 plug, it definitely pulls about 10-15% more load then before; spiking up to about 35% with full video. But hardly overloading it unless you may be running several CPU programs at once. For just internet use it is perfect. But if you use it on a I3 or similar lower power processor, I can see how it may bog down more. On a well running I5 or I7 computer with minimal multiprocessing, it works like a champ. I can guess that reviewer having stuttering and other issues may be overloading the processor, which would definitely cause lots of issues. The adapter gets warm to the touch, so keeping it in a well ventilated area will certainly extend the life. Overall I am quite pleased with it and a good compromise until I have to upgrade my whole system.

I have an older laptop that only has a single HDMI port and can't send video over the USBC, which means it would only run one monitor. I got this because it has an integrated GPU and allows me to connect another monitor. I wouldn't try to run any heavy graphics over this, but for things like web browsing or watching the occasional video it works fine.

OLD review: Pretty much unusable with a 2012 Mac Mini running OS X 10.8.5 and Seiki 40 inch 4k display. It manages to display at 4k, but often flickers or drops out for seconds at a time.REVISED review (2015.2.25):Still may be early to tell, but I've revised my rating to five stars since it looks stable after utilizing a different hdmi cable. I originally used the cable which came with the Seiki, but after switching to another cable I had on hand which is 4k rated with chokes at both ends, it works!Pros: it just worked. No OS X patch necessary, no SwitchX, etc.. Again, this is with OS X 10.8.5, which came with the Mini and is the latest pre-Mavericks OS X release.Cons: Firefox is unusable [revised again, see below]; its pages do not refresh, I have to move the whole app window in order to refresh the page in view after scrolling or clicking a link. I'm not going to take off a full star for that, as Safari, Xcode and other apps appear to work fine. I may have to revise this review down if other apps don't work properly, but for now it's five stars.As far as I know, these cons only apply to OS X 10.8.5 with DisplayLink firmware version 2.3. The product release notes claim that earlier OS X versions (10.6 and .7) are not supported at all and that later OS X versions (Mavericks, Yosemite) have limitations (e.g., "[they do] not correctly support virtual frame buffers").REVISED review (2015.10.15):Still working, this time I'm using it with an old Windows 7 laptop, but I've again had troubles with screen blanking, even when using my "best" hdmi cable. I bought several, all were rated 4k, all had issues, until I bought a StarTech.com cable. It's perfect! No red dots.Also, regarding the 2012 Mac Mini, I upgraded to Yosemite OS X 10.10 and the StarTech.com usb 3 4k adapter still works fine. It also works with that Mini running Windows 7 in bootcamp.This is not a fast adapter for 3D but I have no issues running Visio, Office, Matlab, etc..ALSO, regarding Firefox on OS X, it works! I had to configure Firefox to use software rendering, as pointed out by StarTech.com support. Yes, StarTech.com actually provides technical support.

I recently started work with a new employer and was surprised when the provided laptop could only drive a single external display. I've become very accustomed, as a programmer, to having two monitors--a large 4K monitor with a smaller widescreen monitor in portrait mode to the side; and was not ready to lose the second monitor.Because of port locations and cable lengths, I originally attempted to drive my 4K monitor with the StarTech adapter. It worked, but there was a very noticeable lag--the mouse cursor felt sluggish and would continue to move briefly after stopping movement of the mouse; if you've ever taken control of a coworker's computer over Teams, and you're in the US and they're in Bangalore, it was exactly that. Moving a window that spanned across both monitors caused extreme tearing. I reworked things a bit so I could drive the 4K monitor with the laptop's video and drive the smaller [1080 x 2560] monitor from the StarTech. This allowed it to drive a higher refresh rate and eliminated any perceivable lag. Some cheaper adapters I'd looked at appeared to cap out at 1920 x 1080, so I was glad to see this one had no problem driving the widescreen monitor at 60Hz--and although it "worked" for the 4k monitor, it's only able to drive it at 30Hz and the lag actually makes it feel much slower than that, making it largely unsuitable even for tasks like programming or word processing.Obviously, you're not going to use it for gaming--although likewise you're not likely to do much gaming on a budget laptop without multiple display ports or video-capable USB-C ports. But, for more "productive" types of applications, and driving something closer to a 1080p monitor or projector, it performs well for the cost.

I have tried numerous HDMI adaptors to try and extend my laptop desk top to a third monitor. My 2012 MacBook Pro is certainly on its last legs, but there are too many "duds" out there that claim their HDMI adaptors work with Mac computers... try so many I became a non-believer. Alas! StarTech comes to the rescue with a quality unit which is super easy to install and worked immediately! Please note, this adaptor will not work on OSX software older than El Captain... luckily, that's what I upgraded old faithful to! All you need to do is plug in the adaptor, launch the Mac driver from the supplied installation CD, restart your Mac, then plug in the additional monitor and voila, you're all set. My setup consists of an ancient MacBook Pro running El Captain, one LG 32ML600 32" monitor connected via Thunderbolt to HDMI adaptor and now another LG 32ML600 32" monitor connected via StarTech's AMAZING USB to HDMI adaptor. For regular office use (which is what I bought this for), this does the trick! However, if you are streaming video or playing video games, this may not be the best solution. Picture-wise, the output is OUTSTANDING! I highly recommend this item to extend your desktop. It works with my fossil of a MacBook Pro, it will work for you too. It's worth the money... super happy with this purchase!

Work on Linux Mint 21.1 I have downloaded the official driver from their website, and it worked on reboot.Play nice with nvidia-driver-525.I can see a little lag/ghosting between the HDMI and displayLink monitor. But it's barely noticeable, nothing that would affect workflow.
