How to connect 2 monitors to a pc with one hdmi port, by selecting the appropriate option below:
- A DisplayPort (if available)

How to Connect 2 HDMI Monitors to a PC
If your PC and both monitors support HDMI, the process is simple:

- Plug the second HDMI cable into another available video output (HDMI, DP, USB C via adapter).
- Power on both monitors.
- Click the right mouse button on your desktop and select Display settings.
- To create a continuous desktop, scroll to Multiple displays and select “Extend these displays.”
Ensure that each monitor is detected. If not, click Detect in display settings.
How to Connect Two Monitors to a Gaming PC
Gaming PCs usually have more than one video output (HDMI, DisplayPort, or DVI). Here’s what to do:
- Instead of using the motherboard, use the dedicated connectors on a separate GPU.
- HDMI splitters are to be avoided unless you need duplicate (mirrored) displays, as they don’t support true extended displays.
- Connect each monitor to a different port on the GPU and set up the settings in Windows or your GPU’s control panel (NVIDIA Control Panel or AMD Radeon Software).
Two monitors on a gaming PC also allow you to stream or record gameplay while keeping overlays and chat open on the second screen.
How to Connect Two Monitors to One Computer (Laptop or Desktop)
This is also true for users who are looking for how to connect two monitors to one pc.
- Use your graphics card ports for desktops.
- Use HDMI + USB-C (or a DisplayLink adapter) for laptops.
- If the lid is closed, you may need to change your power settings.
If you have a laptop you can also follow HP’s multi-monitor setup guide for step-by-step instructions and need to connect dual monitors, confirm your device can provide video output over USB-C — this isn’t true of all laptop machines!
Choosing the Right Display Mode
After connecting, press Windows + P and choose among:
- Duplicate – the same screen is shown on both monitors.
- Extend – ‘spreads your desktop across multiple screens’ (productivity)
- Second screen only – Turns off the laptop’s primary screen.
At the bottom of Display settings, you can rearrange screens, set resolution and choose the main display. A lot of users ask how to connect two monitors and make them work together, and the answer is usually to choose Extend. For official guidance, refer to Microsoft’s support page on multiple monitors.

Does Using Two Monitors Affect PC Performance?
Yes — slightly.
- There’s virtually no difference between browsing and office work.
- With all your pixels rendered, you are gaming on your GPU. There’s little hit in performance if you’re gaming on one screen and keeping Discord or OBS on the other.
- Older GPUs will struggle to run high refresh rate gaming (120Hz+), on the dual displays.
If you are a gamer looking up how to connect 2 monitors to a gaming PC, make sure your GPU has enough power and VRAM.
Common Monitor Layouts and Mounting Tips
Many of the users would like to know how to hook up two monitors and the most popular setups are as follows:

If you’re seeking to save table space, switch for a Double Monitor Stand or VESA mounts to line up screens correctly.
