StarTech 2 Port Dual DisplayPort USB KVM Switch with Audio SV231DPDDUA

I work on a site where we have two different computers systems and two different computers for them so being able to switch between both and use dual screens was a big advantage for me. The setup was easy enough, just plugged in and away I went. I've been using a few weeks now, and its working okay just have the one issue that every time I switch computers it reset all open apps to the one monitor, would of been nice if it would let the computers remember what was on each screen instead of having to move the programs every switch.

Bought this early in the pandemic to adapt my desk to both personal and work computers. From day 1 I've had issues with the USB peripherals. The mouse port has never worked when switching, so I've had to plug a wired mouse into the generic shared USB port. Dual displays have been highly inconsistent, and frequently I would have to reboot my laptop after I switched to it in order for one of the displays to detect properly - but don't you dare let the monitor go to sleep as it will be detected wrong again on waking.

I learned something new this week: EDID, or Extended Display Identification Data, is used by the computer to determine it is connected to an external display. Without it, the computer thinks it is not connected. When using a KVM switch, if EDID data isn't reported to the computer, such as when switching between machines, the computer defaults its desktop (at least under Windows). This device does not mimic EDID data; therefore, switching causes the computer to think it has lost its display. EDID Emulation is available, better KVM devices offer it. StarTech is not a "better KVM device", however. They recommend that after buying their overpriced box, that one goes and buys external EDID emulators to overcome this problem - instead of just engineering it into their product. I have to say I'm disappointed; this isn't a cheap import - it is supposed to be a quality device; though I learned this is not the case. Furthermore, I've noticed continued issues when switching. More than half of the time, when I switch, the displays don't come up. I have to switch back and forth numerous times to get the monitors to be recognized. When doing so many switches, I've also noted that keyboard and mouse functions have gotten weird. The mouse wheel will often stop working, the keyboard doesn't register; and the only solution left is to reboot. I am absolutely unimpressed - I strongly recommend individuals consider alternative vendors and avoid the frustrations that I and others have had with this manufacturer. Hopefully, they'll get their act together and fix their faulty designs.

I have had this product for nearly 3 years - simple to set up, switches between Mac & PC with two 2560x1440 displays and logitech wireless mouse / keyboard. Super easy to use - couldn't have hoped for a more trouble-free better product.

I've had this for over a year and it behaves HORRIBLY when recovering from sleep and the supposedly USB2.0 hub is practically useless. For both of these situations, I believe that a firmware update would/could help, but...I don't see that happening. Still for my dual DP with two laptop setup, this is the only viable option. Did I mention it's WAY too expensive for what it provides? :-(

Support about 40 of these and work most of the time but have a high level of failures from keyboard/mouse not working to screens not always detecting. Have to buy several replacements each year. Wish there was an alternative on the market

First, let me note I received this item in exchange for an impartial review. That said, please pay attention and know what you want and need before buying this. DisplayPort is NOT HDMI. They look similar but aren't and unless you have DisplayPort, you'll need an adapter which will delay things. Past that, this is as easy to use as any other KVM StartTech offers. It's not a low end KVM. This is serious KVM for people that want and need a professional product. The scenario this solves is simple - Multiple computers, typically a Desktop and a laptop or two towers and one primary monitor, mouse, speakers and peripherals that you want to share with the two computers. Very simple solution to an annoying problem. The construction is really solid as I said above, it's durable and strong, allows some air flow so heat isn't a huge issue and everything fits pretty as well as it could. Unlike the other KVM switches I've got here, this one started out working great and then got really sketchy. I see a few others noted a few problems. I'll just say I've had the same ones almost identical. HOWEVER, it's easily fixed, very intermittent and is seldom a very big problem. To fix it you hit the button twice. Yet it still does seem weird and my only concern is that it seems to have gotten worse over time, the quick fix may not continue working. As long as you know what your components are, understand DisplayPort vs HDMI, have the adapters if you need them, you'll have this thing out of the box and working in a few minutes. I was hoping I had a bad unit until I saw a few other people post about it. Time will tell.

I would recommend this to anyone with dual monitors and two pc’s. The only issue I had was that Windows 7 kept adjusting the displays when I switched between computers. It was a real annoyance to find all my windows, icons and screen resolutions messed up every time I switched. I finally after about a week of annoyances found a setting in my catalyst control center to disable display polling which fixed the problem for me.

I get dual monitor on both computers, the audio also switches to the computer I'm working on.

Does exactly what I need it to. No muss, no fuss. Took 5 minutes to hook up, and it's worked perfectly ever since.

After installing this, I noticed serious problems typing at normal speeds. This KVM will either drop or transpose characters as you type them, for some peculiar reason. As a consequence, I find myself plugging my keyboard into the machine I wish to use manually, almost defeating the point of having this. Switching between machines will work, but perhaps because they do not feed any information between the machine from which you've switch and the now-missing displays, something seems to get reset, and you find yourself having to fiddle with settings when you return. It does maintain good video quality (otherwise), and not a problem with the mouse. The keyboard issue is serious enough to warrant a 2 star rating instead of the 4 stars I would otherwise give this.

Been looking after lots of these devices for several weeks now and no end of problems. Problems: have to type each key twice at bios level, screens go blank when lost focus or go into powersave mode. Have to switch PC off/on to get video output again. remote desktop comes inactive at times when trying to connect to remote server, have to close down and reopen. These are just a few of the issues, very poor performance for what should be a simple product.

I bought this after speaking with Startech's support team, which while they didn't really know a lot about this product, were generally helpful. First the Good news. Supports DisplayPort to legacy adapters very well. I'm running a 30" Apple monitor (w/powered adapter) and 27" hdmi (passive adapter) between two macs. No video problems. Now the Bad news: The unit doesn't recognize a mac keyboard, (according to StarTech support "no KVM does")so in addition of not being able to use the HOT key switching, the unit won't even pass keystrokes from the dedicated keyboard usb in to either or both machines (I got inconsistent results from this- I tried 2 units). Fortunately, the hub works just fine, so if you place the unit where you can reach it, it will perform well (just don't use the dedicated keyboard or mouse inputs). The unit is well priced at amazon and rakuten, and compared to other solutions (which also have their own issues) it's at least workable. Would hope that their Asian development partners start supporting Macintosh products. There are more than just cheap PC's out there!
