Nothing could be simpler than DisplayPort. But we’ve packed a lot of powerful technology in this small plug and know you might have some questions. If you can’t find the answers below, just hop onto ‘Ask DisplayPort’ and we’ll get back with an answer!
A: There is not a cost effective way to do this. The adaptors that are available only work from a DP computer to a VGA, DVI or HDMI monitor and not the other way around. If you have a desktop you can purchase a graphics card with DisplayPort. Our best advice: Before you purchase a DP only monitor make sure you have DP on your computer.
A: The DisplayPort version 1.2 standard was designed to utilize the Standard Display cable. We did this intentionally to avoid customer confusion. A DisplayPort cable is a DisplayPort cable; EXCEPT if it a “reduced bit rate” (or RBR) cable, which is typically a 15m cable designed for projector applications, and they only support up to 1080P; OR if it is an active cable, which will not support the new HBR2 rate introduced in the DP 1.2 standard.
So a cable that was tested to meet the DP 1.1a requirments also meets the DP 1.2 requirements.
A: Yes. We have published a DP Audio User Guide for help on this topic.
A: No. Thunderbolt technology actually leverages DisplayPort to deliver HD video to displays, helping to move media faster and simplify connections between devices. The support of DisplayPort within the Thunderbolt interface further shows the level of commitment towards DisplayPort within the PC industry. DisplayPort over Thunderbolt continues to support existing DisplayPort monitors as well as DVI, HDMI and VGA video output.
A: Both Apple and Intel remain committed to DisplayPort. Apple continues to be one of the largest users of DisplayPort and Intel announced in December 2010 that it planned to accelerate adoption of DisplayPort. Intel was joined in that announcement by AMD, Dell, LG Display, Lenovo and Samsung Electronics LCD Business.
Likewise, industry analysts remain positive on DisplayPort:
A: DisplayPort v1.2 features must be designed into the Display. DisplayPort v1.1a Displays are compatible with DisplayPort v1.2 PCs though.
A: DisplayPort-to-HDMI adaptors and DisplayPort-to-DVI adaptors are very simple and only operate one way. For instance, when a DP-to-HDMI adaptor is connected to a PC that supports DP++ (Dual-Mode) capability, the PC senses the presence of the adaptor and sends HDMI signals over the DisplayPort connector rather than DisplayPort signals. No signal conversion is performed by the HDMI adaptor. HDMI signals are merely passed through. The unique DisplayPort adaptor capability enables the PC to connect to a variety of displays via the DisplayPort connector including HDMI, DVI, and VGA. VGA adaptors are more complex and perform active signal conversion from DisplayPort to VGA. These adaptors also operate only one way. Unfortunately, HDMI does not support conversion to other display formats as does DisplayPort.
A: DisplayPort does handle full HDMI signaling including sound but keep in mind that implementation of full HDMI signaling is an option the PC manufacturer must choose to enable. It is recommended that you check with the PC manufacturer prior to making a purchase and verify that the PC supports DP++ capability with HDMI. DisplayPort adaptors simply passes through the DVI or HDMI signal. We have published a DP Audio User Guide for help on this topic.
A: DisplayPort v1.2, supports monitor daisy chaining.
A: DisplayPort v1.1a displays are fully compatible with DisplayPort v1.2 PCs and graphics cards. A DisplayPort v1.1a display can be the last display in a DP v1.2 chain.
Here’s an example:
A PC with one DP connector is driving two monitors via daisy chaining. The 1st monitor is a DP v1.2 monitor with input and output connectors. The 2nd monitor is a DP v1.1a monitor. DP v1.2 PC—> DP v1.2 monitor with in & out connectors—->DP v.1.1a monitor.
A: Standard DisplayPort-to-Mini DisplayPort adaptors and cables work both ways between sources and sinks:
A: 2560 x 1600 (WQXGA resolution) is supported over all 2-meter “DP Certified” cables. Some cables, due to their design, may be capable of supporting 2560 x 1600 resolution over lengths longer than 2 meters.
A: If a source device has DisplayPort, such as a video player, and you connect it to a TV then it would send the video to the TV. Currently DisplayPort is primarily found in PCs because the standard is new and easy for the PC industry to implement, but it is not limited to PCs.
A: HDMI signaling is an optional DP++ feature that a manufacturer may or may not implement. DisplayPort adapters merely pass through the DVI or HDMI signal from the PC. It is recommended that you read the product specifications on the packaging and also contact the manufacturer prior to purchasing a product to ensure that the product supports DP++ with HDMI signaling.
A: The reason power isn’t included in standard cables is because both source and sink devices are designed to provide power. Captive, attached cables often include the power wire. If it is desired, for example, that a particular source device utilize the power available from the mating sink device, then that Source device could include an attached or dedicated cable that carries the DisplayPort power signal. Same could be applied to a sink device.
A: Mini DisplayPort connectors are now standardized by VESA and are fully compatible with standard DisplayPort connectors. Audio is an optional feature in DisplayPort v1.1a, and is now supported by several graphics cards and monitors.
A: Mini DisplayPort connectors are now standardized by VESA and are available from several manufactures. Check vesa.org for the latest connectors and cables that are DisplayPort Certified.
A: It’s recommended that you use a DP-to-VGA adaptor for the VGA monitor, and a DP-to-DVI adaptor for the DVI monitor. There are also DisplayPort v1.1a hubs available today that allow you to connect multiple monitors to a single DisplayPort connector.
A: We’re not aware of any issues today with hot plugging DisplayPort.
A: You need to manually select the DisplayPort input in the monitor’s On Screen Display (OSD) with this model.
A: There are DisplayPort v1.1a hubs available today that allow multiple monitors to be driven from a single DisplayPort connector. Various output configurations are available for these hubs including DisplayPort, DVI, and HDMI.
A: HDMI signaling is an optional DisplayPort++ feature that a manufacturer may or may not implement. DisplayPort adapters merely pass through DVI or HDMI signal from the PC. It is recommended that you read the product specifications on the packaging and also contact the manufacturer prior to purchasing a PC or graphics card to ensure that the product supports DP++ with HDMI signaling.
A: A variety of DisplayPort projectors are available from various manufacturers. See this link.
