Windows 7: Using 1 keyboard & mouse for 2 PCs

19 Mar 2019   #11

Win7 x64
Using 1 keyboard, mouse & monitor for 2 PCs

Hi 'townsbg' and 'dg1261':

Still no luck with getting my IOGear to work .

Swapping the IOGear cables between the two computers didn't help. The problem still persisted, although swapping cables obviously meant that the Lenovo PC, which always gets video, came on with a different LED.

So, I'm starting to think it may be my 10-year old HP Compact 8000 Elite that's causing the problems. The boot order issue of the HP machine (which tried to use USB as first boot device instead of the hard drive), though, has been solved. Still, only the Lenovo PC gets video.

As for the LG 24EN33 monitor, it has both an D-Sub (VGA) port and an HDMI port. Of course, before trying to use IOGear I always set the monitor to D-Sub.

Anyway, if I can't get the IOGear to work I guess the only option left is to switch mouse and keyboard between the two computers, that is when I reinstall Win 7 on the HP and use the Lenovo to go online to look for info or download software. Connecting the Lenovo with the D-Sub port of my LG 24EN33 monitor and the HP with the HDMI port (and switching ports with the input switch of the monitor depending on which PC I'm going to use) shouldn't be a problem.

However, can I unplug mouse and keyboard while I install Win7 or Linux 19 on the HP machine and connect them with the Lenovo to be able to google or download something, without interrupting the install process?!

Thanks so much .

Using 1 keyboard, monitor & mouse for 2 PCs

Hi 'townsbg', 'dg1261' and 'F22 Simpilot':

Thanks so much again for your help. And my apologies for not getting back to you sooner .

I ended up not getting the IOGear to work and so did the next best thing.

Without fiddling with the recalcitrant KVM (or maybe my equally uncooperative HP computer ) I probably wouldn't have found out that my LG monitor has 2 ports: an HDMI and an D-Sub/VGA.

So I hooked my Lenovo PC to the D-Sub port of the monitor and the HP to the HDMI. And I keep an extra set of mouse and keyboard ready. So, switching between computers this way is almost as convenient as it would've been with the KVM.

Not sure, if this qualifies as 'Solved'. If you guys think yes, I'll mark my post accordingly.

Many thanks again .

Did you not try Synergy? It's my understanding that both computers just need a local network connection.

Another methoud, though this is just off the top of my head, is to make or buy a crossover cable and connect both computers and use RDP to remote into the other machine. Or, may not even need a crossover cable, just ethernet between the two Comps and your router.

Note: I've never used RDP, though, I have used a crossover cable to share Internet with a laptop with WIFI to a desktop.

This site usually just has the basics, but gives you a pretty good idea on things. The article mentions an external IP address. You'd be more concerned with an internal IP address like, etc.

Windows 7 pro 64-bit sp 1

At the time the OP created his post he needed to reinstall Windows and needed to be able to access the net from the other computer during the install. Can't exactly use RDP until after the reinstall.

Hi 'F22 Simpilot' and 'townsbg':

Many thanks for your latest feedback.

'townsbg' is right in that I didn't use Synergy because it probably wouldn't work while one of the machines has its OS installed (and no Internet during that time).

But since that's been accomplished I think I'll give Synergy a try. So, thanks 'F22 Simpilot' for that reminder.

If all your trying to do is use one keyboard and mouse with two PCs, then you might try Mouse Without Boarders. It is software from Microsoft and works well. IMO.

Hi Pbcopter:

Thanks a lot for the tip and please excuse my late reply .

Right now I'm using mostly Linux Mint 19 because Windoze 10 I recently switched to has a serious problem playing the sound of mkv movies plus quite a few web pages won't load , although they do just fine under Linux.

But I did download the install msi and am going to try it once I've (hopefully) been able to fix the Windoze gremlins).

Many thanks again and have a great weekend,
