Synergy Software

edited December 2020 in Third-Party Software
I have 3 monitors using 2 computers since each computer only has 2 monitor conns each. I have been using 2 kbds and 2 mice since I installed the second computer. Tonight a friend told me about a software app called Synergy. (This maybe known already by the Community but not by me) You install it on both computers and it will let you use I kbd and 1 mouse over all 3 monitors like an extended display even though you are using 2 computers. This is great stuff. $29 for the basic program. symless.com/synergy

    You do not mention if you are using Windows 10 or not. Another solution for those on Windows 10 is to setup and use Virtual Desktops. This might allow you to do away with the use of the second computer. With a group of three key presses you can immediately change thru your different virual desktop with application running and view things. I run three virtual desktops at all times. One with SmartSDR and the other station equipment software like amplifier and rotor interfaces, another one with DXlabs for logging and cluster information and a third with email and other normal daily applications.

    Here is a link to explain, show some pictures and instruction on setup and use.

    If you need to keep the second computer then you can buy Logitech keyboards and mice that use what they call FLOW. This allows the mouse and keyboard to move seemlessly between different computers without having to change the keyboard or mouse. I have used a mouse with Flow enabled and it worked quite well. Here is a link explaining more.

    Last option is if your computer allows for bluetooth connections then there are several keyboards and mice that allow for switching between computers with the press of a single button on the mouse or keyboard. I have used a Logitech M720 mouse and a K380 keyboard to use them on two different computers.

    Of course the most expensive option is to buy a video card that allow for the use of more monitors with a single computer.

    I know you already have a solution with Synergy that works for you and these additional options might not be useful for you. I also tried Synergy back more than a year ago and it did work however at the time it would sometime have a crash and mess up my desktop icons and configurations and I got tired of having to fix them so I tried these other options until I found what worked best for me.

    Right now my station display monitor setup includes a 55 in 4K display in the center and two 24in displays on each side stacked one above the other. I just recently replace the older 21 in display with new 24in HP displays which were on sale for $80 each spec's with Display port connections.

    On another station I use a older Dell Latitude E 6420 i7 that I bought used off ebay for $80 along with a Dell PR02X docking station that I picked up at a hamfest for $20. This allow a total of three monitors natively from the laptop.

    John, thanks for your input. I will try it for a while to see if it messes up. But using the same mouse over all 3, 24" monitors, like it was an extended display, is just awesome.

    I have 3 computers with 5 monitors (in my office - not part of my ham station) using Windows and use the free program "Micrososft Mouse without borders". I have found it very simple to setup and use.

    Stardock also has a similar product, called Multiplicity. I have used it to handle text and mouse clicks on my Thinkpad X1 Tablet.

    Synergy is the only one mentioned that works on windows, macs and linux. I now have 7 monitors and 4 (2 win, 1 linux and 1 mac) machines controlled by it.

    I have been running Synergy for about 4-5 years going between an iMac and Win 10 pc without issues. One mouse and one keyboard it is great. I also had a third win 10 PC and again no issues.

    A little late to the party, but Mouse without borders works perfectly!

    I use barrier which is a fork of the original opensource synergy. I have run both barrier and synergy and have found that the free opensource barrier works better and more features. Save your money and checkout:

    (7 monitors + 1 windows pc + 2 linux pcs + 1 mac) = (1 keyboard + 1 mouse) !
