Need More Than 64 Screens?

For systems that require more than 64 screens then use 1 x VQS01 on each output. The VQS01 expands each output to 4 outputs configured as a 2 x 2 display. The maximum configuration would be 10 x iH4 cards with 40 x VQS01 units providing support for 160 screens or 16 x Vantage4 cards with 64 x VQS01 units providing support for 256 screens. The Datapath display driver software allows you to choose which outputs can be configured with the VQS01, this allows systems to be configured which have a mixture of direct outputs from the card and also expanded outputs using the VQS01.

An example application:

16 x 3 display wall requiring 48 screens, each screen displaying 1024 x 768.

The solution:

Use 2 x Vantage4 cards with 8 x VQS-01 controllers. This configuration would drive the top 2 rows of the display wall. Each output from the Vantage4 card would be set to 2048 x 1536 resolution in an 8 x 1 format. The VQS-01 would split each output into a 2 x 2 format with each screen displaying 1024 x 768. This combination would provide a 16 x 2 wall, covering the top 2 rows. The remaining bottom row would be created using a further 4 x Vantage4 cards with each output set to 1024 x 768

Total requirement: 6 x Vantage4 cards and 8 x VQS-01 controllers. The illustration below demonstrates how the Vantage4 card and VQS-O1 work to create this display wall.
