Syba Sy-kvm20107 4-port Vga Usb Kvm Switch

Worked great and all my systems are linux.

I bought one and installed it but, it would lockup after 30 seconds. Outletpc was great as usual, sending a replacement and picking up the return.The replacement worked much better, but there are a few issues. That's too bad because it it would just do what the documentation said, it would be a great product. This model switches between computers without issue, 99% of the time. Once in a while it just locks up and you have no mouse or keyboard. (like switching video modes). The documentation says that the green led will be lit when an active computer is plugged in. This was not the case in the bad unit or in this one. It is only green on the computer you are on. I have 2 full time pcs and 2 other part-time pcs, even with all 4 on it only shows green on 1. Another issue is the audio jack. The unit is supposed to allow your to share the speakers between computers. It does, but there is a noticable humm in the port and if there is no audio coming through, it sounds like it's "sparking" inside. I just disconnected the jack.So i have no audio through the unit. It is not critical form me or i would have sent the second one back.All this leads me to believe that quality control is a probelm for syba. If you just need switching, this will work fine and it does come with all the cables to connect 4 pcs. But you might want to keep looking.

Just what the doctor ordered for my switching between 4 machines. I am not using the vga side of things because my monitors have enough inputs to handle all 4 computers (with digital inputs like dvi and dp), so i'm just using this for audio/mouse/keyboard. I'll take 1 star away because the audio pops loudly when you switch between inputs, but i'll add it back because i only paid $20 for a warehouse deals return. Great deal!

Works great - and as described by the manufacturer. Now, if my hp pavilion g7 with radeon video didn't have a memory leak in the driver software - i wouldn't have any issues at all. At least the latest driver from amd solved the every 10 minute swap between displays (i'm running the display on the laptop and a second 24 inch monitor and extending the display). Apparently, there's a bug in the radeon driver software that causes random behavior exhibited by swapping the displays (if you've extended them). With the updated driver, it's now down to every 3 or 4 hours instead of every 10 minutes (which is still a major pain in the you know what, but it sure beats every 10 minutes).This works perfectly on my old trusty and reliable hp dv8000 (which is now 11 years old and still running like a champ). Works perfectly on my home built server too.What i truly liked about the usb ports on the face of this switch box is the ability to have a central memory location that is shared between computers for quick temporary storage. Others have mentioned you need to turn off green power saving features on your attached computers. This is true! If you don't disable the green feature (allowing things like the display to go to sleep if not in use) you'll run into all sorts of trouble with kvm switches (all of them, not just this one). If the video hardware runs active all the time, when you swap between computers, the display hardware is active and doesn't have to wake up to launch the user interface. This allows near instantaneous switching between computers. If you run your usb ports active all the time, you can hot swap the memory between computers (i have a 32g thumb drive that i have plugged into one of the extra usb ports and it hot swaps in about 2 to 3 seconds between computers (sometimes a little longer if there are a lot of extra drives attached on other usb ports of that computer - since it has to resolve everything in the drive list if you have file manager/file explorer up and running on that computer when you swap out to it)). To put it bluntly - this is a great device and has saved me a bundle of headaches by allowing me to have one central monitor and the ability to extend the display to the active laptop computer i have on my desk. I do recommend plugging this animal in to a wall socket since it will make a big difference in keeping any thumb drive active and discoverable between switching events. Oh yeah, i'm running windows 10, windows xp, and windows server 2012 enterprise edition. So, no real issues on any of those operating systems (unless windows 10 is what is causing my radeon video hardware to act weird).

Just what the doctor ordered for my switching between 4 machines. I am not using the vga side of things because my monitors have enough inputs to handle all 4 computers (with digital inputs like dvi and dp), so i'm just using this for audio/mouse/keyboard. Great deal!
