5. To change the resolution, click on the monitor you want to adjust and select a new display resolution from the drop-down menu as shown below:


6.  如果你不确定选择什么分辨率,通常最好从每台显示器的原始分辨率开始。原生分辨率是指显示器在不缩放的情况下可以支持的最高分辨率。例如,一台原生分辨率为1280x1024的19英寸显示器可以显示分辨率高达1280x1024的图像,而无需缩放。

7. Once you have selected the resolution of your monitor, a prompt will appear allowing you to keep the changes or restore as shown in the image below:

How to run dual monitors with one HDMI port


By using an adapter or HDMI splitter, you can run dual monitors with one HDMI port.Let's take a look at each of these methods.

How to Use an HDMI Splitter to Set Up Dual Monitors

To set up dual monitors with an HDMI splitter, follow these steps:

1. Find the HDMI port on your computer.

2. Once you locate it, plug one end of the HDMI splitter into this port.Then, plug the two HDMI cables into the splitter.

3. Next, connect one end of each cable to a monitor.However, if your monitors have different inputs (for example, one is DisplayPort and the other is HDMI), you must use the correct cable/adapter for each monitor.

4. Finally, turn on your monitor and computer; you should now see your desktop stretched over two screens.

One thing to keep in mind is that not all HDMI splitters are created equal.Some splitters only support certain resolutions, so choosing one that works with your specific setup is critical.Another consideration is whether you need an active or passive allocator.Active splitters are generally more expensive but perform better, especially at longer distances.If you're connecting two monitors together, a passive splitter should suffice.

How to Set Up Dual Monitors Using an Adapter

There are various adapters, so choosing one that is compatible with your computer and monitor is crucial.Once you have the adapter, connect it to your HDMI port and monitor.If not, you may need to change your computer's display manager settings.

VGA to HDMI Dual Monitor Using Adapter


If you have a computer with a VGA output and want to connect it to an HDTV or monitor with an HDMI input, you'll need to use an adapter.Converting VGA to HDMI is not complicated, but there are a few things you need to keep in mind:

1. You first need an adapter that can convert from VGA to HDMI.These are widely available and relatively inexpensive.

2. Then, you need to make sure your computer's video output is set to the correct resolution.Many adapters only work at certain resolutions, so it's critical to check your adapter's specs before making any changes.

3. Once everything is set up, connect the adapter to your computer's VGA output and connect it to your HDTV or monitor's HDMI input.

Dual Monitor Setup on Game Consoles
