Right-click on your desktop, open the NVIDIA control panel, click on "Change Resolution," and select the appropriate monitor to adjust its settings.

Note: When using multiple monitors, it's important to ensure that your power supply is sufficient. While a single GTX 780 Ti can handle three monitors, you may want to consider upgrading your power supply for safety and stability, especially if you're overclocking.

Upgrading your power supply

Determining Power Requirements

The central processing unit (CPU) and graphics card are typically the biggest power draws in a PC. When upgrading to support three monitors, it's essential to account for the increased power demand. Calculate the total power draw by summing up the power requirements of all your components, including the CPU, graphics card, hard drives, optical drives, and cooling systems.

Selecting a Suitable Power Supply

When choosing a new power supply, opt for one that meets or exceeds the total power requirements of your system. It should also have the correct cables and connectors to match your components. The most common size is the ATX standard, which fits almost all full-sized desktop computers. However, some cases may require smaller form factors or non-standard sizes, so ensure you select a power supply that physically fits your computer case.

Efficiency and Form Factor

Modern power supplies come with efficiency ratings, often indicated by the "80 Plus" voluntary certification system. This means that the power supply consumes no more than 20% over its output wattage. There are different grades within the 80 Plus system, indicating higher efficiency and usually a higher price. Additionally, consider the form factor, which refers to the physical size and shape of the power supply. The most common form factor is ATX, but some cases may require smaller sizes or have specific dimensions that you need to accommodate.

Cable Compatibility

Ensure that your new power supply has the correct cables to connect to your components. The three crucial types of cables are:

• Main motherboard cable: This cable connects directly to the motherboard and usually has 20 or 24 pins.
• CPU motherboard cable: This cable powers the CPU and comes in 4, 6, or 8 pin varieties.
• GPU power cables: These cables provide power directly to the graphics card and typically use 6 or 8 pins.

Installation Process

Once you've selected the appropriate power supply, it's time to install it. This process involves removing the old power supply, disconnecting all the components, and then reversing the process with the new power supply. Ensure you work in a well-lit area and use a standard screwdriver. Do not open the metal casing of the power supply, as it contains high-power capacitors that can be dangerous.

Using the NVIDIA Control Panel

To set up three monitors with a single GTX 780 using the NVIDIA Control Panel, you'll need to ensure that your graphics card and monitors are correctly connected and configured. Here's a step-by-step guide:

Step 1: Connect the Monitors

Before proceeding, ensure that all three monitors are securely connected to your NVIDIA-based graphics card. Check that your graphics card has enough ports to support multiple monitors. If not, you may need to purchase an additional graphics card or use ports on both your motherboard and the graphics card, which may result in some performance loss.

Step 2: Open the NVIDIA Control Panel

Right-click on your desktop and select the NVIDIA Control Panel from the popup menu.

Step 3: Navigate to Multiple Display Settings

Under the "Display" category in the NVIDIA Control Panel, select "Set up Multiple Displays." This will open a page listing all the displays connected to your system and the corresponding GPU.

Step 4: Select the Displays to Activate

Check or clear the checkboxes to select the displays you want to use. In non-SLI modes, you can select up to two displays per GPU. In SLI mode with GeForce 8 series and later GPUs, you can select up to two displays connected to GPUs within the same SLI group.

Step 5: Apply the Configuration

Click "Apply" to activate your new display configuration. If any of your displays aren't showing an image, repeat steps 3 and 4, or restart your computer and try again.

Step 6: Adjust Display Settings

By default, when a display is first activated, it is set to "Extended Mode." This means that your desktop will be extended across all the selected displays. You can drag the green boxes in the NVIDIA Control Panel to match the physical arrangement of your monitors. You can also choose which monitor is primary by right-clicking on it and selecting "Make Primary."

If you prefer to have the same image displayed on all monitors (also known as "Clone Mode"), right-click on one of the display icons, select the display you want to include in the Clone group from the pop-up menu, and then click "Apply."

You can switch back to Extended Mode by right-clicking the display icon box of the Clone group, clicking "Extend," and then clicking "Apply."

Troubleshooting:

If one of your displays isn't showing up in the NVIDIA Control Panel, click "My display is not shown..." to force detection. You can also try playing with the cable connections and using different cables to see if that resolves the issue. Ensure that all connections are secure.

Additionally, if you're experiencing issues with your display resolution or refresh rate, as in the case of the user with the 144 Hz monitor, you may need to adjust these settings manually. Right-click on your desktop, open the NVIDIA Control Panel, click on "Change Resolution," select the monitor in question, and then adjust the resolution and refresh rate settings as needed.

Using GPU scaling

If you're experiencing a noticeable drop in performance on system/non-gaming programs when using a dual-monitor setup with a GTX 780, there are a few suggestions to fix this. First, make sure you have both displays set to GPU scaling. To do this, go to the Nvidia Control Panel, then to 'Adjust Desktop Size and Position', and finally, select 'Perform scaling on GPU'. If that doesn't help, go to your BIOS and change HPET to 64-bit. Another potential fix is to downgrade GeForce Experience to version 2.1.1 or earlier.

Using a second video card

If you opt for another GTX 780 Ti, you can expect similar performance and compatibility as your current card. This option may be more expensive, but it ensures that both cards have the same specifications and features.

On the other hand, choosing a different model for the second video card can offer a more cost-effective solution. However, it's important to consider compatibility issues and potential performance discrepancies between the two cards.

To set up the second video card, you'll need to connect it to your system and configure the display settings. Ensure that your power supply is sufficient to support both cards, and refer to the specific instructions for your hardware and operating system to complete the setup process.

Additionally, when using multiple video cards, it's important to consider the physical space in your computer case and the cooling requirements of the cards. Proper ventilation and airflow are crucial to prevent overheating.

By following these steps and considering your specific hardware and setup, you should be able to successfully use a second video card to run three monitors with your GTX 780 Ti.
