Want to know what cables do I need to connect a second monitor to my pc

Is the cable working? try reducing your laptop screen resolution and connect to your monitor. Your monitor may not support full hd resolutions....

What exactly is the problem?
Do you know the type of cable connection you have on the monitor, HDMI, PCI, PCI-E, VGA?
The computer is rather old but it looks like it has one VGA and one HDMI connection, all you need to do is use a cable that matches the connection type on the PC to the type on the monitor. You can get cables that have the same connections on both ends or you can get cables that use different connector types on each end or use an adapter. It's rather simple to find whatever cable or adapter you need but we need to know what connector the monitor has.

Your monitor is telling you that it thinks it is not receiving a video signal from the computer. You need to verify which of three components is not working, the computer, the cable, or the monitor.

The first thing to do, obviously, is to check that the cable connecting the computer to monitor is good. You will need some extra components to do the checking. I'm going to assume that the cable is detachable at both ends.
First you can try replacing the cable with different one. If the replacement cable works, then it's the cable.
Secondly, you can try different monitor. If you connect this in place of the first monitor, and it works, it's a faulty monitor (needs repairing or replacing).
Third try a different computer with the original cable and monitor, if it all works it looks like the video on your PC has malfunctioned. (This might also be your conclusion if a system comprising a different cable and monitor fails to work with the original PC)
You might just be able to verify the cable by testing the connectivity of all the wires in the cable with a meter, if you knew the pin out of the cable at both ends.
If you find out the computer is getting a signal out, there could be many causes for that, each having its own solution (or not as the case may be)

Hi Ron,

It sounds like the monitor is not receiving a signal, or that the signal is one that it can't display (wrong screen resolution etc).

Can you make sure the monitor cable is securely plugged in at the monitor and the PC?

Do you have another PC you can try with that monitor?

Do you have an spare monitor cable you can try?

Is this the only monitor connected to your PC or are you using is as a second monitor?

I'm happy to try and help you solve this.

Kind regards,

Chris

Well, all you have to do is make proper connections.
There must be two power cables. 1 for PC and 1 for monitor.
No video input message indicates that the video (VGA) cable is not connected. It is Video input cable, the Blue one with same connector at both ends. Connect it with your monitor and secure it properly. Its other end is required to be connected to the blue output connector at the back of the PC.

Let me know if any further clarification is required. Hope this helps!

Hi,

There are two ways to do this.

First and simplest is to simply shutdown the pc, disconnect the analog from the back of your PC and connect the DVI cable to the PC and monitor. When you turn it back on the PC will detect and switch to the DVI.

Second, and better to compare. Connect both sets of cables and go into your display settings, then select advanced options. You should see a GeForce tab in the advanced menu. On that tab there is a multi monitor display setup. Set it to mirror to both screens and apply.

Once it's set switching inputs on the monitor SHOULD work. The problem that makes it a "should" is that both the monitor and the video card have the ablility to sense a connection. So, even with mirroring setup you may have to use the first method as you can't have both connected and operational at the same time.

Give these a try, if you're not sure how to get into the display settings, comment back here with your windows version and I will give you a step by step

it looks like port on your PC where monitor connected gone bad, now you can double check this connecting your PC to another spare monitor not the one which is already working, even one more thing sometimes it does happen that cable you are using with your PC might not be passing good enough signal to the port , I know same monitor works on other machine but we want to find out actual port back on your PC so its worth second option to try another cable.

but if another monitor or cable swap doesn't work then that means display connection port gone bad, you might need to consider changing graphics card.

update me if any problem or if you have more questions regarding this.

thanks.

You need a standard Male To Male Vga Cable for this monitor.

Not sure If I am understanding this correctly, you are trying to connect a monitor to a monitor? I have never heard of that before. As far as I know you need a video card that has dual output to use dual monitors. I am not saying you can't do what I think you are saying but I never heard of that before. Also on a side note depending on the resolution and amount of colors your operating system is set on, you need a video card strong enough to drive both monitors.
