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 3.3v DC power on pin 20. 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 3.3v, 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 20.
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 3.3v DisplayPort signal type.
A different active adapter that converts the HDMI TMDS signal at 5v to DisplayPort LVDS at 3.3v 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 18. DisplayPort specification is 3.3v on pin 20. 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.

HDMI to DisplayPort (DP) Conversion Information
This article contains information about HDMI to DisplayPort (DP) converters.
HDMI to DisplayPort Conversion
There has been some confusion when using HDMI to DP or the opposite way adapters on Dell systems. There are two types of conversion adapters that can be used. The first is an active adapter and the second is a passive adapter type. Most adapters only carry a one-way signal.
When you convert video from a source that uses DisplayPort or Mini DisplayPort to DVI or HDMI (ex: a computer to a monitor). 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.

Dp adapter to hdmi
There are probably a million different reasons you might want to move an HDMI signal over to a DisplayPort signal. But if you’re someone who wants to take advantage of DisplayPort’s unique properties, like its ability to handle UHD content with higher refresh rates, then you’ll need to be a little more selective with the adapter you choose to get that job done.
Choosing the Best HDMI to DisplayPort Converter Adapters
The good news is that when you’re trying to pick a good HDMI to DisplayPort converter adapter, there’s really only three or four things you need to concern yourself with. The bad news is that unless you’re prepared to think about how you plan on setting up your own converter adapter in very concrete terms, then picking the right one will be much more difficult.
In many ways, build quality is the most obvious thing you should consider. But it can also be very easy to overlook. If you plan on using your adapter in a mobile capacity, then you’ll want to pay special attention to the quality of its build. Because for that type of use, you need the adapter to be able to be plugged in and out, over and over.
Time can wear down those connection terminals. But well-built adapters are constructed to endure thousands of connections, provided you don’t try and store them in a swamp or similar extreme conditions. Conversely, if you’re someone who plans on plugging in the adapter and never touching it again, then you can be less concerned with the overall build quality.
Because as long as you don’t end up with a dud, and as long as you’re not subjecting the adapter to extreme environmental conditions, just about any decent HDMI to DisplayPort adapter should serve the purposes of a non-mobile user. It really only needs to plug-in and work, right?
How long is the cable that runs between the HDMI connection and the DP connection? That will help determine how close together the two devices you’re connecting need to be. You’ll also want to consider the length of the included power connector because any active converter adapter will require an extra power source to work as an active adapter.
In most cases, that power source is provided through USB, which means a USB cable is included with the adapter. You might find alternatives to USB power connections, like DC power connections. But USB power is usually the simplest and most reliable way to get the job done because it doesn’t require you to get another adapter or power-box involved.
Most people won’t have to worry about this. But if you’re interested in accessing higher refresh rates, like PC gamers may be concerned with, then you’ll want to think about the version of HDMI and DP supported by the converter adapter that you’re using.
Reaching 30Hz while running a UHD 4K resolution is something just about any adapter ought to be able to provide. But how does the adapter perform running at 1440p? How about 1080p? Reaching higher performance standards is only possible when you’re working with the latest versions of the DisplayPort format. For people who expect to run high refresh rate content at lower resolutions, these types of questions can be quite important.
Cable Matters HDMI to DisplayPort Adapter
Like its name suggests, the Cable Matters HDMI to DisplayPort adapter helps connect your PC or laptop up to an HDMI display with a DisplayPort input. You’ll need a DisplayPort cable, which isn’t included with this kit, in order for the HDMI male to female adapter to work. But once you’ve got the USB power cable all connected, you ought to find this is one of the most efficient and reliably adapters you could ever hope to get your hands on.
Design & Layout
When compared to a lot of similar adapters, Cable Matters delivers what could be called a generally superior quality. Because this isn’t a brand that makes adapters and cables on the side, it’s their main focus as a brand. It’s easy to see that focus in the design of their products. Here you’ll notice gold plated connection terminals on the ends of the adapter, helping to protect the connections from corrosion.
The housing of each adapter is made from sturdy ABS, which is both impact resistant and able to handle heat pretty well. The total adapter weighs about half of an ounce, which is reasonably lightweight, as you might expect. Aesthetically, the only thing to point out is the Cable Matters logo is embedded on the topside of the DisplayPort portion of the adapter. That makes it a little easier to determine which portion of the adapter is which.
The USB 2.0 Type-A male power connector runs about three feet from the center of the adapter. The cable connecting the DisplayPort box to the HDMI format runs about six inches. Using the adapter is a tiny bit complicated because you need to plug in the additional power connector if you want this adapter to be an active converter adapter. But the added step isn’t too challenging.
Once connected properly, this adapter provides active HDMI to DisplayPort conversion. That means you can transmit high definition audio and video from your PC to a DP monitor pretty easily, and expand your workspace to a second monitor. The 4K video resolution support means you’re covered for resolutions up to 3840 x 2160, at least while running at 30Hz.
If you’re willing to drop down to 1080p, you’ll find support doubles to 60Hz. You can also get 60Hz while running at 1440p, at least if your video card happens to support it.
Keep in mind that this isn’t a bi-directional cable. It operates solely from HDMI to DisplayPort. You cannot take DisplayPort content and move it over to HDMI.
StarTech.com HDMI to DisplayPort Converter
Like Cable Matters, StarTech is another brand that’s specialized in making these sorts of cables and adapters. Here you’ll find the StarTech HDMI to DisplayPort Converter works to convert HDMI content over to the DisplayPort format, allowing you to connect a laptop or desktop alongside a DisplayPort monitor.
In that sense, this adapter strives to improve your productivity while viewing the documents, spreadsheets, and multiple websites across several screens. You can also capture 4K content being sent through an HDMI source, and view that content on a DisplayPort screen. But it’s not all about productivity. This adapter lets you connect with an Xbox One, PS4, and any other compatible gaming console you might want to use alongside a DisplayPort display.
Design & Layout
The StarTech HDMI to DisplayPort Converter is reasonably small and portable, measuring 6.69 x 5.59 x 1.18 inches, and weighing about an ounce and a half. Because the cable only runs about six inches, you need to have everything pretty close for everything in your setup to reach without needing extension cables.
As you’d expect, this is an active video adapter, which explains the USB Type-A male connection that’s connected with the HDMI portion of the cable. StarTech makes a lot of different adapters like this, so the general quality of construction here is quite good. For instance, there are small textural indents and rises which help you get a firm grip against the base of the cable. That makes each cable head much easier to connect or disconnect from your devices.
While running the 4K support, you’ll find that you’re restricted to 30Hz. But you can run content at a higher 60Hz refresh rate if you’re willing to drop outside of UHD resolutions. Because the HDMI is format 1.4 while the DisplayPort is format 1.2. Basically, that’s ideal for someone who’s concerned with running higher refresh rates on 1440p content.
It’s unfortunate that they didn’t go above and beyond with specially plated connection terminals. But this sort of basic utilitarian design is easier to appreciate if you’re on a tight budget. This adapter includes a three-year warranty from StarTech, in addition to lifetime customer support from Star Tech.
QGeeM HDMI to DisplayPort Converter
The QGeeM HDMI to DP converter has a plug and play design that’s easy to appreciate. In terms of its capabilities, you’ll find it’s great for both mirror mode and extended mode, which closely imitates the capabilities of the other adapters on this list. And as a high performance HDMI to DisplayPort adapter, this converter is capable of connects laptops, desktops, Raspberry Pi 3 Model B kits, and similar devices without issue.
Design & Layout
The Philzli HDMI to DisplayPort Converter is available in a wide range of different sizes. They can be found running anywhere between six inches and 100ft. Actually, the 4ft option is typically the most cost effective variant. And for people who can’t get their stuff connected with a tiny 6” cable, four feet really ought to do the trick, which makes that the sweet spot for a lot of different people.
The USB power is made with a Type-A connector. The size of the USB-A connection head is quite small, measuring about 1.8” in length. And the size of the core adapter is equally quite small, measuring 1.69 x 0.71 x 0.31 inches. It’s worth noting you’ll find gold plated connection terminals, except for the USB-A connection, which is only running power so wouldn’t really benefit from the added effort.
If you do need much longer cables, those options are clearly present. Unfortunately, these much longer cables tend to be a little pricy because the QGeeM HDMI Converter is an active adapter, which tend to be a bit pricier than passive devices. Which is part of the reason why this device supports UHD 4K content, running 3840×2160 at 30Hz.
Alternatively, you can run 1080p @ 120 Hz. Quite handy for PC gamers who plan on maintaining high refresh rates. But you don’t need to be a PC gamer to take advantage of this kind of thing. These cables work well with game consoles like the Xbox One S, allowing you to run content in 1080p without issue.
Like the other converter adapters this list, you’re not looking at a bi-directional device. It cannot be used for running a DisplayPort connection over into an HDMI connection. But it does include an 18-month warranty from QGeeM.
Picking Between 3 of the Best HDMI to DisplayPort Converter Adapters
The Cable Matters HDMI to DisplayPort Adapter uses a really clever design. For the DisplayPort and HDMI portion of the device, it only stretches about six inches, which is all most people really need. But it stretches three feet for the power connection, which makes it far more versatile than adapters like the StarTech HDMI to DisplayPort adapter.
If you’re looking for top quality adapters and you’re willing to pay a little more, you might want to consider the StarTech.com HDMI to DisplayPort Converter. It’s not the right choice for everyone because it only runs about six inches in length. But for reliable adapters that are made to last forever, it’s tough to beat StarTech. Their considerable warranty and customer service are actually pretty respectable.
The QGeeM HDMI to DisplayPort Converter doesn’t have the same kind of strong reputation as Cable Matters and StarTech. However, they do have the best options out there for HDMI to DisplayPort adapters that run more than 30 feet in length. If you’re looking for adapters that can go the distance, literally, then you’ll probably want to pick up a QGeeM HDMI adapter.
