Compliance Overview - Members Only

The VESA DisplayPort Compliance Program provides several benefits:

• Supports the brand by insuring interoperability and licensing the brand logo for identification of compliant products by consumers.
• Enables measurement of compliance in real products.
• Provides reasonable measures of acceptability.

Products that pass this level of acceptability are added to the Integrators List and have the right to license the DisplayPort Certified Logo. Please reference the Compliance FAQ section if you have further questions.

The VESA DisplayPort Compliance Program is managed by the VTM, DisplayPort’s compliance administrator.

Test Houses

VESA certified 3rd Party Test Houses have been trained to perform tests for specific product types. Vendors are encouraged to pre-test their products in their own labs prior to submitting them for testing at a certified test facility. To earn the opportunity to receive a DisplayPort Certified Logo for your product(s), each product must pass a series of tests as described in the PHY Layer Compliance Test Specification and Link Layer Compliance Test Specification.

Checklists

Compliance Checklists are a simple set of questions measuring product compliance in areas that are difficult to test. Checklists are very valuable tools for designers as the product are being designed and debugged.

VESA recognizes some DisplayPort enabled products are very similar (Example: different color of packaging) but may still have different product SKU's or model numbers. In an effort to not create extra work for product makers by requiring these similar products to be tested, VESA has established a Qualification by Similarity Guideline (see below).

At the conclusion of the testing, the tester knows whether the tested device is DisplayPort compliant, and if the device is considered to be compliant, the appropriate paperwork is sent to VESA via the compliance administrator VTM.

The Certified Logo License

Usage of the DisplayPort logo requires a product to be compliant as demonstrated by passing the DisplayPort Compliance Program. In addition to successfully completing the DisplayPort Compliance Program and having their product included under their company name on the Integrators List, companies must complete:

• The DisplayPort Certified Logo License Agreement to be eligible to use the logo in conjunction with the product. The DisplayPort Certified Logo License Agreement and Usage Guidelines for the DisplayPort logo are available as a PDF download here.
• The DisplayPort Certified Logo License Agreement must be signed for access to the logo artwork and the right to use the logo with products that pass DisplayPort Compliance Testing and are included in the Integrators List.

After earning the certified logo and completing the appropriate paper work you have earned the right to use the compliance logo. Your product will be listed on the DisplayPort website according to product type.

VESA Sponsored Interoperability PlugTests

DisplayPort Interoperability PlugTests are members-only events held regularly to promote DisplayPort product development, help foster communication between DisplayPort product manufacturers and ensure that DisplayPort products operate together. Our goal is to eliminate interoperability problems by ensuring proper implementation of DisplayPort products.

PlugTests are held about once a quarter at hotels in various locations and typically run for four days. Private test sessions are also scheduled between vendors. During these test sessions, the vendors validate that their products work well together.

Qualification by Similarity Guideline

When products are very similar, testing of one product may allow the other similar products to be added to the Integrators List without re-testing. If any "significant differences" exist between products, testing of each is required. The definition of "significant differences" is sometimes debatable and the final judgment is the responsibility of the VTM, the compliance administrator, who reports to the VESA Board of Directors. As decisions are made on what are "significant differences," the rules of thumb will be listed here. The ultimate responsibility for making sure that various production product models do not have "significant differences" from the product samples tested lies with each vendor. Audits by VTM that reveal discrepancies between shipping product and samples tested may be cause for required re-test, revocation of certification, and/or legal action.
