I'm building a new computer and i also am useing the MagicJack for my phone service(works great but computer must be on 24-7)so i was wondering if i could hook up the new com. with the white cable and my old com.with the blue cable.(monitor has both) that way i don't have to keep the new one running all the time.

If your monitor has two inputs (sounds like it does) then yes, you can plug two PC's into it and switch between them as required.

I think that you would need some type of KVM switch (http://www.newegg.com/Product/Product.aspx?Item=N82E16817395001)
to actually do that.

Monitors with multiple inputs will have a input switch button on it.

Actually TWolfe,
Your input is valid. Unless a KVM; Keyboard, Video, Mouse; type switch is enabled then there may be issues between having both computers on at the same time.
My recomendation is for a KVM switch.

My monitor has both a DVI (white) and VGA (blue) port, however, my monitor does not have an input button to switch between the two. In order for me to connect and use 2 devices (in my case my computer and my XBOX360), one of the devices needs to be turned off (or standby - not giving input to the monitor).

What I do is if i want to use my XBOX360 while my computer is on, I turn off my computer (or standby) and then power up my 360. Then once I'm done playing I turn the 360 off and power up my PC again.

Hmm that's too bad, I have two monitors, both have a input/source switch.

Of all the monitors I used so far, those that have two video inputs all have switching capability. Either by pressing a single button on front, or by traversing the monitor menu with couple of button presses.

Like Gerritt said above, the real solution is a KVM, unless you don't mind using two keyboards and two mice for controlling the computers. It can get pretty confusing sometimes, not to mention wasting desk space. A KVM will enable you to use just one set of input controls, which is more convenient.

At one point I setup two computers this way: KVM for K and M only; while the monitor take care switching the V. It took two steps to switch from one computer to another. But the benefit was the DVI port, which give higher quality display for one of the PCs.

If a high quality display is not of concern, well then I would have to say a KVM is definitely the way to go.

However, you state that one of the PC's must be on 24/7 because of your phone service - do you actually need to be able to check it that often?

If not, you could just use one input on the screen, and literally change the cable when you want to switch between views - using a cheap KVM for just K and M (as someone stated they do above). This would be the best solution, particularly if your monitor has the capablity to switch between inputs (which any modern monitor with multiple inputs should).

Check in the manual or menu of the monitor for a component select button. If it's not available then buy the KVM.

I was just researching an LCD monitor problem on Dell's website and happened to read in a support forum that their LCDs will not display anything when a video signal is being received from both the VGA and DVI inputs. Don't know if that is true or not, haven't tested it myself. Makes sense though because their monitors auto-sense whether it is a digital or analog signal and set themselves accordingly. Also don't know if this would apply to non-Dell monitors, but am guessing it may. Just something to be aware of.

Correction: I have since read in a Dell LCD manual that you can connect both the DVI and VGA inputs as long as they connect to different computers.

Almost every monitor now has a DVI (white) and VGA (Blue) inputs. In that ase you can hook one to one comp and the other to another but you would have to switch inputs on the monitor every time. Some monitors have a nice button that you can instantly change inputs with, but the ones that don't can be a pain.

Way to go for being "green" and helping reduce carbon emissions "MagicJack" company!!! Obama and Gore will be so disappointed with you.

I'm going to pester my Representative to introduce a "MagicJack" carbon tax in the House next week.

OK so I am now in process on getting a new GTX285 hooked up, but I don't see ANY indication of VGA, vs. HDMI or any other color coded diferential. Nor did my old 8800GTX.

Is this color coded thing something that is manufacturer specific?
