" ... I get good, consistent switching with no devices dropping off or needing to be restarted, reconnected, etc. ... KVM comes with all of the cables you need. ... All video inputs into switch are HDMI, plus USB 2.0/3.0 for mouse and keyboard. ... "
" ... Now I can work from home and easily toggle back and forth between my personal and business computers BOTH with dual screens and a steady webcam. ... Gained working desktop space by 3 square feet (CKL HDMI KVM Switch 2 Port Dual).
... I highly recommend working smart and savvy. ... "
" ... I am currently using this with a MacBook Pro & a PC and it's great with 2 monitors. ... I did need to pay attention to the fact that the docking station I was using with the Mac didn't have any HDMI out, so I was using 2 adapters (DP -> HDMI & USB-C -> HDMI). ... So I switched to 2xHDMI-out dock, and the Mac worked flawlessly. ... "
" ... I was doing a lot of research on KVM switches. ... Since working from home, I needed something that I could use to switch between my home PC and work laptop. ... "
" ... hooked up three different PCs/laptops and they all immediately setup the displays in extended mode (what i wanted) . ... "
" ... Loving the KVM switch (and being able to click back and forth between my work laptop and my home Desktop on the two monitors. ... "
" ... This switchbox will seemlessly switch dual HDMI monitor setups with convenient hotkeys. ... It will even feed a USB hub through a front port to allow you to switch USB devices between active computers. ... The only limitation I have run into is that I use a MAC trackpad on my setup at work. ... "
" ... I've been working from home for several months now and have two work laptops, a personal laptop, and a desktop computer. ... I don't have that problem with the audio on any of my 3 other computers. ... My personal laptop is a Macbook and it works with that as well. ... "

" ... I’ve had it for 3 months and it just died on me. ... "
" ... So only after six months worth of use two of the four ports have stopped working. ... "
" ... Doesnt work nothing but issue after issue, very frustrating for something so simple. ... "
" ... I figured it was just a faulty product, so I returned it via amazon prime and requested a replacement, then waited for a new one to try. ... But the fact that I received two faulty products in a row goes to show a lot about the manufacturer. ... "
" ... Now after several months, the device is showing signs that it is about to fail completely. ... Over the past two weeks, I have had to manually reset it almost daily. ... "
" ... Very unreliable and disruptive. ... "
" ... The first time it came back after disconnecting everything and reconnecting them back, ready to return it when it magically started working again. ... It is still not working. ... "

" ... The build of the switch is solid metal and the connections are tight with the cables. ... It worked well with an adapter that I had for cable that was DVI. ... Make sure you have the adapters if needed and connect all the cables. ... The audio cables work well if you have the line out and mic plugs on your PC. ... "
" ... It took me a little while to get the cables worked out. ... "
" ... This could have been a problem if one needed different length, but I contacted customer service and they custom ordered som shorter cables for me! ... "
" ... I needed a cable replaced and they replaced it no issue. ... "
" ... I have zero complaints - took me 10 minutes to setup, and most of that was cable management. ... "
" ... This matters because it requires double the cables that the single monitor display would require. ... "
" ... for both devices without having to change around a bunch of cables. ... "
" ... KVM comes with all of the cables you need. ... "

" ... Liked the availability of a wired-remote - have not used it yet! ... "
" ... The remote is very small and desktop friendly. ... "
" ... It has a lot of connections so it isn't small or pretty once it has a nice wired remote so you can hide everything behind the desk. ... "
" ... 3) The remote switching options are fantastic with options to use a wired remote, or double click the middle mouse button, or a keyboard sequence. ... I tend to use the wired remote mostly and the mouse. ... "
" ... I use the little wired remote it comes with. ... "
" ... Given the remote switch (which is an unexpectedly great feature), my only suggestion to the manufacturer is to add mounting slots so that it could be attached to a vertical surface or the underside of a desk. ... "
" ... The remote is nicer than I thought. ... "
" ... The feature I like the most is that you can hide the KVM switch box and use their small wired remote to switch between your PCs. ... "

" ... Interestingly I found that I could actually run the full resolution on both my computers at 5120x1440, but only at 70hz or 75hz. ... "
" ... However with my Dell Thunderbolt dock/XPS laptop I couldn't get the #1 screen to go full screen and was blurry, no matter what monitor or cables I used. ... "
" ... Not a huge monitor or anything - 24-inch ThinkVision, pretty standard. ... Still, getting a message on the monitor saying it was not set to the right resolution and it started to blank out for a second or so now and then - sometimes more now than then. ... BUT, could not get the card to recognize the LG correctly and let me set the resolution. ... Once I did that, the LG was seen correctly by the card, all issues went away and I could set the resolution correctly. ... Also, the message on the monitor itself that the resolution was not correct has gone away. ... "
" ... Having an issue when using the Samsung U28E590D with the HP only (mac mini works fine), the screen periodically goes black and will say message "not optimum mode recommended mode 3840x2160 30hz". ... "
" ... -Frame rate is limited to 60hz at all resolutions (59hz and 50hz offered at 1920x1200 and 1920x1080, respectively) ... "
" ... When I push one of the station buttons I expect to see a login screen. ... This morning, I tried to get in, fiddled a bit and finally got the login screen. ... "
" ... 30Hz maximum refresh rate for 2x 4K was not made particularly obvious in the ad, and I didn't realize the limitation until after purchase. ... "

" ... however the Lenovo running the latest Windows 10 seems to detect when the switch to the Macbook pro has been made and then gets stuck in a continuous loop of resizing until the system crashes. ... I've tried updating various video drivers and such for my Lenovo but no luck. ... "
" ... I hate renting an operating system like Windows, where they OWN and CHANGE everything on an UPDATE or whim to sell more OFFICE software. ... "
" ... CKL does not even appear to have it's own web site so there's no one to turn to. ... "
" ... I tried all the obvious things, trying the reset commands, disconnecting the two computers and turning off the power, etc. ... "
" ... I ruled out 'user error' and after a ton of troubleshooting, now realize it is the switch that is faulty. ... "
" ... It took a lot of fiddling to figure that out and get it to "work", but Windows keeps wanting to change it back to 5k120 or 5k60 for random reasons . ... "
" ... Really annoying when you're coding or writing email, etc. ... After much messing with the card and reinstalling MSI Radeon software several times, I finally connected the LG monitor directly, bypassing the KVM switch. ... "

" ... Suddenly no sound! ... "
" ... There is a very noticeable high pitch noise. ... I believe the high pitch noise is coming from the KVM because my speakers connected directly to my PC does not make this noise. ... I'm debating about returning it mainly because of this noise. ... "
" ... I also found the sound port to cause a lot of static/interference with my speakers, so if sound quality is important be warned. ... "
" ... The switch makes a loud beep when it first turns on, and when switching between PCs. ... I have been able to turn off the switching sound, but the power on beep is annoying. ... "
" ... And the beep after a power cycle's pretty loud. ... "
" ... Additionally, routing audio through it is VERY disappointing. ... There is a constant scratching whistling noise that comes over the audio. ... "

" ... I recently got two BenQ 4k monitors and needed to upgrade the CKL HDMI version with one that supports DisplayPort in order to reach the 60Hz or greater instead of the 30Hz. ... The price of the 4 port dual DP cost the same as one of the 4k monitors but it was worth it. ... - Both mid 2015 MBPs work great and the resolution scaling performance is not impacted by the KVM. ... "
" ... So my setup - 2 x LG widescreen HD monitors, with a Dell D6000 dock and Dell laptop (work) and a Surface Dock with Surface Laptop 2 (personal), and a Logitech K330 wireless keyboard and a M705 mouse, both on a single unifying transmitter. ... "
