The DP2HD4KS DisplayPort to HDMI adapter enables you to connect a DisplayPort-equipped desktop or laptop computer, such as the HP EliteBook 8570p / 8470p, to an HDMI display. This adapter is compatible with DisplayPort 1.2 & HDMI 4K @ 30 Hz and as a result can support video resolutions up to Ultra HD (4K) as well as the accompanying digital audio up to 7.1 channel surround sound.

With support for resolutions up to Ultra HD (4K) the DP to HDMI adapter ensures you can convert DisplayPort to HDMI while maintaining an astonishing picture quality four times the resolution of high-definition 1080p. The adapter is also backward compatible with previous DisplayPort revisions 1.0/1.1 with support for resolutions up to 1080p.

For a hassle-free setup the DisplayPort to HDMI adapter allows for plug-and-play installation without any additional software or drivers. Plus, with a small footprint and lightweight design, the adapter maximizes portability.

To ensure compatibility with any DisplayPort output the DP adapter offers an active conversion. Active video conversion is required to maintain 4K resolutions when converting DisplayPort to HDMI. An active DP adapter is also ideal for outputting 1080p video resolutions by ensuring compatibility with graphics cards that are not capable of outputting multi-mode DP++ signals (e.g. ATI Eyefinity). 

The DP2HD4KS is backed by a 3-year StarTech.com warranty, and lifetime technical support.

Frequently Asked Questions

Troubleshooting

When you troubleshoot issues with a video adapter, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • Video cables

  • Video adapter

  • Video source (such as a DVD player or computer)

  • Video destination (such as a monitor or projector)

To test your setup components, try the following:

  • Use the cable, video adapter, video source, and video destination in another setup to see if the problem is with the components or the setup.

  • Use a different cable, video adapter, video source, and video destination in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

  • Test each cable individually.

  • Use short cables when you are testing.

When you test the video source and video destination, it is recommended that you do the following:

  • Remove the video adapter from your setup and test to make sure that the video source and video destination work together without the video adapter.

  • Test to make sure that the video source and video destination work together at the resolution that you want to use.

Note: In order for your setup to work properly, the video source, adapter, and destination all need to support the resolution that you are using.

Check that the device is not being used in reverse.

The display does not support the resolution set within Display Settings. Adjust the resolution to be the exact resolution and refresh rate recommended by the display manufacturer.

If a DisplayPort converter with audio is not passing sound from the source to the destination, complete the following:

  1. Make sure that the DisplayPort connection on the video card is the default audio playback device.
  2. Make sure that the video card has the DisplayPort audio codec installed. If not, visit the video card manufacturer's website to find out how to update the video card driver.

Common Issues

Using the On-Screen Display menu for the display, enter the Menu system and go into “Picture Mode” then “Aspect ratio” and change from “16:9” to “Just scan” or “1:1 pixel mapping.”  The wording may vary depending on the manufacturer of the display.

How To

To arrange extended displays on Windows 10, complete the following. 

  1. Press the Windows key+R, type desk.cpl, and press Enter. 
  2. Under the ‘Multiple Displays’ selection, select ‘Extend Desktop To This Display.’  
  3. Press ‘Identify’ to determine what number each display is assigned to. 
  4. Drag and drop each display accordingly to the physical layout on your desk.  
  5. Click the Apply button. 

To arrange extended displays on macOS, complete the following. 

  1. Navigate to the Apple Menu > System Preferences, click Displays, then click Arrangement
  2. Make sure that the ‘Mirror Displays’ checkbox is not selected. 
  3. Click on each display to determine what number each display is assigned to. 
  4. Drag and drop each display accordingly to the physical layout on your desk.  

Before You Buy

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.

Unfortunately no, this device has an intended source and an intended destination.  Refer to the title of the webpage for this order.

Didn't work

By: Peter1292 - 06/19/2017
Didn't work at all. Tried two different screens and laptops and different DP ports without success. Other DP cables working fine though.

Thanks for sharing your experience with us. We hope we can help. While it’s possible your adapter is faulty, We also wanted to check what resolution and refresh rate you are using with the adapter? This adapter only supports up to 4K at 30Hz. If your tested displays are using 4K @ 60Hz, that may explain why it wasn’t working. We also sent an email to you at the address left with your review.

Small adapter very useful

By: macphoto19703 - 03/11/2018
I used this adapter with a new small form factor system and found it worked really well My desktop did not have HDMI but did have Displayport. I found this cable to be simple to use, just plug and worked, with a simple HDMI cable and voila it was up and running. I had no issues with resolution and picture quality was great. I like the small cable on the adapter vs some other products that have just the adapter. I found the flexibility of the cable easier to work with and I had less restrictions on making cables all fit because of this. Overall i would recommend this product for its ease of use and its solid build I received this product in exchange for an unbiased review

Quick and Simple in a Nice Package

By: NickD_CA40 - 03/13/2018
I have tested this DisplayPort to HDMI dongle on a few computers with different resolutions and it has been working well for weeks. The adaptor comes in a small zip lock bag. It is slightly longer than my hand from wrist to finger tip. It is made of very nice materials with smooth modern glossy black ends and a strong yet flexible cable. The adaptor plugs into the DisplayPort jack on the computer or docking station then allows an HDMI cable to be connected to it. Both sound and video were converted without any issues. I tested multiple resolutions including above 1080p and all worked well. Once connected video and audio came just as quickly as if I didn't have an adaptor connected at all. This adaptor was easy to use, just plugged it in and it started working. I received this product in exchange for an unbiased review.
