Dual-link DVI, Single-link DVI, DisplayPort and 2560x1600 resolutions with PCoIP products (15134-1607)

The information below describes the various display connectors (ports) and explains how they are used with a focus on achieving resolutions of 2560x1600. Depending on which PCoIP device you have, you can have multiple display connectors that have different uses, such as:

DVI-A (analog video only):

Can be used for analog displays using a DVI-VGA adapter cable.

DVI-I (integrated digital and analog video):

 

Can be used for digital displays with DVI cables or analog displays with a DVI-VGA adapter cable.

DVI-D (digital video only):

 

Can be used for digital displays with DVI cables.

DisplayPort (DP):

Can be used for DisplayPort displays with a DisplayPort cable or DVI displays if a DP-DVI adapter cable is used.

Individual DisplayPort links can support dual-link data rates when operating in DisplayPort mode supporting resolutions of 2560x1600. They can also provide single-link data rates when operating in DisplayPort++/DVI mode

MiniDisplayPort (mDP):

Can be used for Mini DisplayPort displays with a mDP cable or a mDP-DP cable or DVI displays if a mDP-DVI adapter cable is used.

Mini DisplayPort links can support dual-link data rates and 2560x1600 resolutions.

Single-link DVI (SL-DVI):

 

The DVI specification allows a maximum pixel clock of 165 MHz to be used on a single-link DVI video signal. The highest 60Hz-refresh VESA resolution supported by single-link connections is 1920x1200.

Dual-link DVI (DL-DVI):

NOTE: These dual-link connectors can support either single-link data rates OR dual-link data rates.

Dual-link DVI doubles the number of data pairs, which allows resolutions requiring an effective pixel clock of up to 330Hz to be supported. The highest 60Hz-refresh VESA resolution supported by dual-link DVI connections is 2560x1600.

Notes:

  • PCoIP zero clients only supply single-link data rates through each DVI connector.
  • Dual-link connectors are provided to allow for all digital DVI cable types to be used.
  • Single-link DVI cables can be plugged into dual-link DVI connectors and will pass single link data rates, provided analog pin compatibility is maintained.
  • Dual-link DVI cables require dual-link DVI connectors and can NOT be plugged into single-link DVI connectors. Analog pin compatibility is also required.
  • To achieve 2560x1600@60Hz resolutions on a dual-link DVI capable monitor via a PCoIP zero client, you must use an adapter cable to combine two single-link DVI data outputs into a single dual-link DVI connection.

Connecting Monitors to TERA2140 Zero Clients

PCoIP TERA2140 based zero clients utilize 2 imaging processors each capable of supporting a full dual-link DVI rate. Each imaging processor is normally split to provide 2 single-link DVI connections (i.e. 1 and 3 for one processor and 2 and 4 for the other), for a total of 4 single-link DVI displays supported per client.
 
Quad DVI zero clients.

  • DVI outputs must be paired to support dual-link resolutions such as 2560x1600 @60Hz. DVI connectors 1 and 3 are associated with one imaging processor; DVI connectors 2 and 4 are associated with the second imaging processor.
  • When using the double ended DVI cable (Y cable) for 2560x1600 @60hz resolutions ensure the following:

For a single monitor 

    • Y cable port 1 is plugged into zero client labeled port 1.
    • Y cable port 2 is plugged into zero client labeled port 3.

For a second monitor at 2560x1600 @60hz

    • Y cable port 1 is plugged into zero client labeled port 2.
    • Y cable port 2 is plugged into zero client labeled port 4.

Note: Failure to connect the cables up correctly will lead to a no source signal error.

Supported DVI Teamings

NOT Supported DVI Teamings

Maximal 60Hz display configurations are:

  • 2 displays at 2560x1600
  • 1 display at 2560x1600 and 2 displays at 1920x1200
  • 4 displays at 1920x1200

Quad DisplayPort zero clients

  • Individual DisplayPort links can support dual-link data rates when operating in DisplayPort mode. They can also provide single-link data rates when operating in DisplayPort++/DVI mode. DisplayPort zero clients do not require and do not support videohead pairing as do the quad DVI zero clients. Hence, DisplayPort mode must be used for dual-link resolutions such as 2560x1600@60Hz.This will be determined by the cable used. Typically active adapter cables support DisplayPort mode while passive adapter cables support DP++ mode (single link data rate).
  • DP++ to Dual Link DVI conversion is not supported.
  • Maximal 60Hz display configurations:
  • 2 displays at 2560x1600
    Note: When connecting to a soft host (VDI) only, a further single-link display up to 1920x1200 can be supported in addition to the two 2560x1600 displays.
  • 1 display at 2560x1600 and 3 displays at 1920x1200
  • 4 displays at 1920x1200

Connecting Monitors to TERA2321 Zero Clients

For Dual DVI and DisplayPort zero clients

  • TERA2321 zero clients come with integrated DisplayPort and a DVI-I connectors as well as dual DVI and dual DisplayPort units. Only one DisplayPort can be used to achieve the maximum resolution of 2560x1600 @60Hz
  • Display configurations with maximum resolutions at 60Hz are noted below.
    • 2 displays at 1920x1200
    • 1 display at 2560x1600

Connecting Monitors in a Remote Workstation (Host Card) Solution

  • PCoIP host cards come with either dual or quad miniDisplayPort (mDP) producing a single maximum display resolution of 2560x1600 @60Hz.
  • GPU configurations with maximum display resolutions at 60Hz are noted below.

Quad mDP

  • 2 displays (GPU feeds) at 2560x1600
  • 4 displays (GPU feeds) of 1920x1200
  • 1 display (GPU feed) at 2560x1600 and 2 displays (GPU feeds) at 1920x1200

Dual mDP

  • 2 displays (GPU feeds) at 1920x1200
  • 1 display (GPU feed) at 2560x1600

Notes:

To reduce the chance of display issues, connect the lowest numbered port on the GPU to the lowest numbered port on the host card and continue upward.

When configuring 2560x1600 resolutions from a GPU with both DVI and DisplayPort connectors, start with connecting the lowest GPU DisplayPort connector to the lowest host card connector and continue upward.
