Q&A for How to Set Up Dual Monitors

It may be because your monitors are the "wrong" way around (i.e. your system thinks the monitor on the right is actually on the left). Try moving your mouse off the "wrong" side and see if it appears on your second monitor.

Make sure your mouse is plugged in properly. Sometimes just unplugging it for a few seconds and then plugging in back in gives it a reset.

Yes, if there's a DVI, VGA, HDMI/Thunderbolt. You might only be able to hook up one monitor because of your graphics card, though.

Windows+P will bring up the projection settings on a PC. You can then select "extend desktop" and select which you want to be the primary monitor and which the secondary, and drag the monitor position to determine which is the left and which is the right.

The best price/performance gaming card is currently the nVidia GTX 1050 / 1050 TI, the 1050 TI has better performance, but costs a small amount extra, if you wish to pay a lower price, i would recommend something along the lines of a GTX 750 ti or a GTX 660

Yes, it works just as if it was on the same monitor. Just copy and paste like you would normally, and it will work.

A VGA splitter does not add an extra display -- it simply duplicates the existing cables. The best way to think of this is to use a river as an analogy: if you have one river, which splits into two, it is still the same water, as opposed to having two separate rivers to begin with.

Yes - you can try a Y cable which will allow you to connect two monitors. In order for this to work properly, you must have good graphic memory on your PC (for smooth performance).

Go to the notifications tab on the bottom right of your screen. Click 'project,' then click 'extend.'

You should be able to just drag your mouse to the left or right, depending on what side you placed your monitor, and it should just carry over.

If set up correctly, you can move the mouse off screen, and the mouse will reappear on the other monitor.

No, you need it directly from the "source." I have never heard about that, so I don't think that is possible. either you need an adapter or you have 2 ports -- 1x VGA and 1x HDMI.

Check your "Project" settings; it seems that yours are currently set to "Duplicate," which I believe is the Windows standard. You always want to set them to "Extend."

The easiest thing to do is to buy a docking station with the types of video connections you need for the monitors you have.

Your mouse will travel across both monitors; access the screens the same way you would as though they were separate windows on the same screen.

You would need an adapter to split the cables.

No, it's like you are using only one computer in two monitor. One pointer at a time.

You most probably need to adjust the audio outpuet settings on your Mac; you can find these under the Sound menu in System Preferences. If that doesn't work, you might also need to change the settings on your TV. Finally, if neither of these things work, you may need a separate audio-out cable to connect your Mac to the TV's audio input.

Depending on your graphic card and your screens, there can be many reasons. This question cannot be answered without additional information.

That's because you're using a splitter. A splitter splits a single signal and send it to two monitors. Your computers has no way to know there's more than one monitor attached, and no way to send different signals to each monitor.

You have 2 options: Use a USB capture card, like an Elgato Cam Link or a generic 20 dollar HDMI2USB connector. Your other option is an app called Spacedesk, which has a bit of lag, but allows for wireless connectivity to save ports.

Yes, as long as you hook one up to the motherboard and the other to the graphics card.

Right click and drag the ones you want on the second display and click Move Here.

A graphics card with multiple output connections and maybe an adapter for the monitors. Hook up one using HDMI and the other using DVI. Or, if both monitors have HDMI and your graphics card has HDMI and your motherboard has HDMI as wel,l hook them up that way. In other words, one monitor to graphics card the second monitor to the computer's motherboard. Then go into system > Display click detect (click Extend My Desktop) and a 1 and a 2 will show up on each monitor. If the one you are sitting in front of (primary display) has a 2 on it, simply click on it in the dialog box and drag it to the other side (left) of the 1 display and they will switch. The screen will go black, then click yes to save changes.

The "Arrangement" option only appears when your 2nd monitor is connected and turned on.

The "Arrangement" tab only appears after the second monitor is connected and powered up. That's how it works on Catalina 10.15.4.

It is because you either did not uncheck the "mirror" checkbox on Mac or if you are on Windows, select "extend" instead of "duplicate".

Try to check whether or not your computer/laptop is compatible. If it is, then check if all ports or wires are fine; sometimes dust or breakage can render a port unusable. If these don't help, have a computer expert friend troubleshoot for you.

1. Check if your computer and motherboard can support dual monitors. 2. Try switching the port connection as well (connect the second monitor to the port that was connected to the first one. 3. Try just connecting the second monitor as a standalone to see if it works. 4. Try the monitor on another system as well to see if it works. 5. It could be software as well; call your device manufacturer's tech support to update your computer's firmware and video drivers.

Yes, provided you change the lid action settings in Windows to prevent the laptop from going to sleep upon lid close.
