HDMI to DisplayPort and DisplayPort to HDMI Conversion Explained

Have you ever tried to connect a DisplayPort cable in your conference or training room to your display or projector through a DisplayPort table jack and it won’t work? What if the only available port on your display is DisplayPort, and your computer is HDMI – will that work? To avoid frustration, we must carefully consider DisplayPort signal path conversion early on, during AV system design.

An example of a relatively simple AV system could include: A display on the wall with only HDMI inputs, and a wall-plate directly below that has HDMI and DisplayPort jacks that connect to the HDMI inputs on the display. A user connects to the wall-plate using DisplayPort, selects the correct Input on the display, and they are off and running – right? Not so fast; there needs to be a conversion from DisplayPort to HDMI somewhere, and if that converter is not in the right place it will not work. This often causes frustration and misplaced blame. You might think why not just put that converter behind the display, right at the HDMI input port so the user does not see it or behind the wall-plate, but you would be wrong.

You should not use an adapter to convert DisplayPort to HDMI anywhere in the signal chain other than right at the source. Here’s why:

  • The DisplayPort provides v DC power on pin Most DisplayPort cables do not have this pin (or it is not connected inside the cable) because it will cause a short-circuit when connecting source to sink.

  • DisplayPort natively outputs in a LVDS signal type that is not compatible with HDMI (HDMI uses TMDS). It does have a dual-mode version that will support TMDS in compatibility mode.

  • DisplayPort signals operate at v, even when using TMDS in compatibility mode. HDMI TMDS signals operate at 5v.

  • An external adapter allows a dual-mode DisplayPort output to send TMDS signal, and also bumps the voltage up to the standard HDMI 5v.

  • These adapters are powered by pin 20 in the DisplayPort receptacle, and can only be used right at the source device – if they are used with a DisplayPort cable in front of them, the signal does not get converted because no power is available on the DisplayPort cable pin

  • This type of DisplayPort to HDMI adapter is one-way only and MUST be used at the DisplayPort source receptacle.

You cannot use the above adapter in reverse – to adapt an HDMI signal to a monitor’s DisplayPort receptacle even though the gender is a perfect match. A different type of adapter must be used when going from HDMI to DisplayPort:

  • The HDMI specification does not support the DisplayPort LVDS signal type, and if the HDMI TMDS is plugged into a DP monitor, it will not work.

  • The DisplayPort receptacle on a monitor or display will only accept the LVDS v DisplayPort signal type.

  • A different active adapter that converts the HDMI TMDS signal at 5v to DisplayPort LVDS at v is required.

  • This conversion process uses more current than the power pin on the receptacle can provide and must be an externally powered adapter.

The DisplayPort and HDMI device receptacles both provide limited power on a single pin to power some external devices such as adapters, converters, active cables, and basic switches. A wall-plate, patch cable, or table cubby jack breaks this power signal chain. You cannot use an HDMI cable with built-in extender in most situations because they draw power from the missing pin.

The HDMI specification for source and sink devices provides 5v power on pin DisplayPort specification is v on pin Most cables do not have this pin – it is missing. And if it wasn’t, it could result in a short. Look at any reputable HDMI or DisplayPort cable and see for yourself – there is either no contact on one of the corner pins or that pin is not electrically connected.

Damage can occur to the connected devices if this pin is electrically connected and some of the off-brand cables do just that. Any time a reputable patch cable is used in the signal path this power connection is broken as it should be.

Can't convert HDMI to DisplayPort - root cause?

HDMI is a clock-less video format, DP uses a clock to keep video in sync.

DP adds the clock to the video at the sending device; so a DP-receiving device needs to see a clock on the incoming video, HDMI doesn't. This is why it's very easy with a simple adapter to go from a DP output on a laptop to a HDMI input monitor because the monitor doesn't care about the clock.

When going from HDMI to DP, the DP-receiving device is looking for a clock; HDMI sender does not have one, so this does not work. You need an 'active' adapter in this case and all that adapter does is add a clock to the video format and sends it out via DP. Notice I said "active" adapter--that's the magic word you need to look for when getting an adapter to go from HDMI to DP.

It has absolutely nothing to do with the age of the video format (as another user put it "older standard"). HDMI is newer than DP and the issue would still exist for the very reason I stated above.

HDMI vs Display Port Explained

3ft (1m) DisplayPort to HDMI Cable - 4K 30Hz - DisplayPort to HDMI Adapter Cable - DP to HDMI Monitor Cable Converter - Latching DP Connector - Passive DP to HDMI Cord

When you convert video from a source that uses DisplayPort or Mini DisplayPort to DVI or HDMI (for example, a computer to a monitor), you will need to consider the difference between passive and active adapters.

If the source supports dual-mode DisplayPort (also known as DP++), then you can use a passive adapter because the source can perform the conversion. If the source does not support DP++, then you need to use an active converter, which includes additional chips to perform the conversion.

Thunderbolt ports support DP++ natively. To run multiple monitors from the same computer, refer to the Active Adapters section below.

Passive Adapters

Passive adapters are less expensive since they do not need to include additional chips. A quick way to check whether you can use a passive adapter is to see if the DisplayPort or Mini DisplayPort source has the DP++ symbol above it. The symbol is a D with a P inside of it, with two + signs to the left, one on top of the other.

Active Adapters

Active adapters use additional chips to make the conversion inside the adapter, regardless of whether the source supports DP++. This means that active adapters are more expensive than passive adapters.

If you want to use multiple monitors with the same computer, you should use an active adapter because some video cards cannot run the maximum number of monitors while using DP++. This is especially true if the computer has more than one DisplayPort or Mini DisplayPort connection. Check with your video card manufacturer to confirm which type of adapter you need for the setup that you would like to run.

Note: You should use passive adapters with StarTech.com MST hubs, except when you are converting from DisplayPort to VGA, since that type of conversion requires active adapters.  For more information on using adapters with StarTech.com MST hubs, refer to the following FAQ: http://www.startech.com/faq/mst_hubs_passive_vs_active_adapters.

Surface Dock

If you experience issues when you connect passive video signal adapters to the Surface Dock, Microsoft recommends that you use active video signal converters instead. StarTech.com offers an active video signal converter for DVI monitors (MDP2DVIS) and for HDMI monitors (MDP2HD4KS).

Note: This issue does not apply to the Surface Pro 3 Docking Station.
