Set up

How do I enable three independent displays?

See how to enable three independent displays with Intel® Graphics Controllers.

How do I switch displays in three-display configurations?

You can use the Windows + P keys to switch to a three-display configuration.

Supported systems and configurations

Which Intel® graphics and chipsets support three independent displays?

See a list of Intel® Graphics Controllers and Chipsets that support three displays.

Which operating systems support three-display configuration?
  • Microsoft Windows 7*
  • Microsoft Windows 8*
  • Microsoft Windows 8.1*
  • Microsoft Windows® 10
What three independent display configurations are supported?

See tables and find other information about supported configurations for three displays.

If Intel® Wireless Display or Intel® WiDi is connected in a multi-display configuration, can four displays be active simultaneously?

Only three displays can be active at one time in a multi-display configuration. The system considers Intel® WiDi one of the displays in a three-display configuration.

In a three-display configuration, can I set two displays in clone and one in extended display configuration?

No, you must set all three displays either in clone configuration or in extended display configuration.

Are three-display configurations supported using a USB display?

No, using a USB display does not support three-display configurations.

Does clone mode in triple display support Blu-ray* disc playback or Intel® InTru™ 3D Technology playback?

No, triple display clone mode does not support Blu-ray* disc and Intel® InTru™ 3D Technology (stereoscopic 3D or S3D) playback.

How many audio streams do Intel® Core™ Processors support in multiple display configurations?

See audio streams supported in multiple display configurations.

Resolution

What is the maximum resolution supported in three independent display configurations?

See maximum resolutions supported in a three display configuration.

Why are few resolutions listed in Intel® Graphics Control Panel when three-display configurations support more?

Only resolutions that maintain display scaling on all three displays are listed in the Intel® Graphics Control Panel.

Why doesn't the computer set 2560x1600, 1920x1200, and 1920x1200 resolutions in a three-display configuration on Intel® Processors?

Applies to the following Intel® Processors:

  • 3rd Generation Intel® Core™ Processors
  • Intel® Pentium® Processors 2000/G2000/G2100 Series
  • Intel® Celeron® Processors 1000/G1000 Series

For the processors listed, system display configurations can affect resolutions:

  • Refresh rate of the panels should be less than or equal to 60 Hz
  • Bits per channel (BPC) of the content should be less than or equal to 8 BPC
  • We recommend setting scaling to maintain display scaling in Intel® HD Graphics Control Panel/Graphics and Media Control Panel
  • Monitor timings
  • DisplayPort monitor maximum link rate should be supported (1.62 Gb/s vs. 2.7 Gb/s)
  • Passive or active dongle must support the resolution
 
Why do resolutions differ when monitors are connected in three-display configurations?

Monitor timings and resolutions are all different. When you connect or disconnect a monitor from your computer, the resolutions may change based on the configuration.

Why is 1920x1200 resolution not shown in a three-display configuration on the second and third monitors?

Applies to the following Intel® Processors:

  • 3rd Generation Intel® Core™ Processors
  • Intel® Pentium® Processor 2000/G2000/G2100 Series
  • Intel® Celeron® Processor 1000/G1000 Series

The 3rd Generation Intel® Core™ Processors limit the pixel data throughput to 180 MHz for second and third DisplayPort devices. The processor may limit the second and third DisplayPort devices from displaying 1920x1200. The configuration requires 180 MHz or more.

Dongles

Do three-display configurations support passive dongles?

Three-display configurations support passive dongles if the system manufacturer has programmed the BIOS to support dual-mode interoperability.

  • DisplayPort > HDMI
  • DisplayPort > DVI
  • DisplayPort > VGA
Note See display combinations for valid passive dongle configurations based on the connected display.
 
Do three-display configurations support active dongles?

Yes. We have validated DisplayPort > VGA active dongles only.

Note See display combinations for valid active dongle configurations based on the active dongle type. For example, if you are using DisplayPort > HDMI dongle, DisplayPort is the source and HDMI is the end interface.
 
What is the maximum resolution supported when using dongles?

For active dongles, the maximum resolution depends on the dongle capability and monitor capability. For passive dongles, maximum resolution depends on monitor capability. See monitor manufacturer documents for details.

Troubleshooting

What should I do if three independent displays aren't working?

Contact your computer or motherboard manufacturer. Determine if your model supports three displays and what configurations are required. We provide general information about Intel® graphics features. Manufacturers can incorporate customizations that may not support all general graphics features.

Why is one external monitor in my three display configuration undetected by Intel® Graphics Control Panel?

A monitor may not show up in the Intel® graphics user interface if the bandwidth/dot clock exceeds maximum allowable limits. The graphics driver dynamically detects displays in the Intel® Graphics Control Panel based on the bandwidth availability.
