BENFEI 4K DisplayPort to HDMI Adapter, Uni-Directional

The review: The adapter seems to be made well. It was in a plastic bag rather than a box, but it did have a protective cap on the male DisplayPort end, and a plastic wrap on the housing of the HDMI end. It plugged in solidly, and I tested the release with no issues. I wonder if some of the people who had issues with it breaking off when trying to remove didn't realize that DP has an active retention mechanism that has to be depressed to remove. Seamlessly transferred both video to my TV and audio to my surround sound, as expected (or at least hoped). I always like to put my personal experience in my reviews too because I search questions and reviews for information, so I feel like this can help others: Active versus passive adapters: I'm using a Lenovo M83 Tiny PC as my home theater PC, which has a DisplayPort++ output. As others have stated, this is a passive adapter and MAY not work with your output unless it is labeled DP++. The DP++ stands for "DisplayPort Dual-Mode", and simply means that the port automatically recognizes if an HDMI or DVI adapter is attached, and sends the appropriate signals rather than the DP signals. Now it is important to realize that most modern DP ports are dual mode, whether the DP++ logo is present or not. As such, you should do the research before hand to find out if your device has a dual mode port, or risk finding out the hard way. Audio through adapter: My primary concern with this adapter was whether or not it would carry audio from the DP to the HDMI cable going into my surround sound receiver. To clarify, my setup is, PC Display Port > this adapter > HDMI cable > Receiver > HDMI cable > TV. When I initially booted the computer (first boot after installing Windows 10 Pro), Windows immediately displayed video on my TV, however no sound was playing on the surround sound speakers (I was clicking the Windows volume slider and listening for the "ding"). Through Control Panel (not the garbage Windows 10 Settings app, what was wrong with the Control Panel, Microsoft?!), I went into the Sounds options. Under playback devices, there was only one item listed, "Speakers". However, almost immediately while I was in the sound options, another device showed up with the name being the model number of my receiver. Windows automatically set it as the default device. I went ahead and disabled the other "Speakers" device just to be safe. After rebooting, all settings remained and sound continued to work properly. If you are using a surround sound receiver, you should also click on the playback device and select Configure. In here, I was able to specify that I have 5.1 surround, but there were also other options such as stereo and 7.1, so make sure you pick the right one. If you are running this directly into a TV, stereo is the default setting, which is what you want. It does send a test sound to each speaker individually, so I was able to verify that the 5.1 signal was actually making it through the adapter. Now whether this is an uncompressed PCM signal or some sort of compressed audio stream is yet to be determined; but this may depend on the source media/application that is providing the audio. Edit from future me: This does support 4K as well. I saw somebody else say it doesn't, but they must be having issues with other parts of their system (source, or receiver not supporting 4K passthrough, etc.). I have slightly changed my setup listed above, and am now running the HDMI cable directly to the TV. I upgraded to a 4K TV, but my receiver does not have 4K passthrough, so I had to bypass it. Now the HDMI cable plugged into this adapter runs to the TV, carrying both video and audio to the TV. TV is receiving 4K from the PC, no problem. I can listen to the sound through the TV speakers, but I don't as I am using a TOSLINK cable to carry the sound back to the receiver. I need to upgrade my receiver to one with 4K passthrough and audio return channel to simplify my life but that costs money and would only potentially reduce the number of cables I need by one. However, I already have to return audio from the TV to the receiver via TOSLINK because I want the TV app audio to come through my surround sound speakers too, so in the end it's all the same.

Works as intended

My second monitor only came with a regular HDMI cord, and the ports on my desktop were DisplayPorts, and this product did exactly what I needed it to! Now I have a 2-monitor setup that was easy to put together and has worked seamlessly. The price is pretty good, too.

Probably works well for other applications but didn't work for what I wanted to do. I needed to convert an HDMI output signal from a laptop to a KVM switch, to a DisplayPort (DP) outlet signal. I realized I needed a powered "active" HDMI to DP adapter, and bought that which did work. Specifically I bought the "BENFEI HDMI to DisplayPort, Uni-Directional HDMI (Source) to DisplayPort (Display) Adapter" here on Amazon.

I bought the BENFEI DisplayPort to HDMI adapter and have been using it ever since. It appears to be made of high quality materials. This uni-directional adapter connects a DP 1.2 computer to an HDMI 1.4 screen. It supposedly features a built-in advanced IC chip that handles the signal conversion. The value is good for a compact gadget that fits in a pocket. It supports 4K at 30Hz and 1080p at 60Hz. The gold-plated connector helps with signal performance, while the latching design keeps everything secure. Just remember that this only works one way, from the computer to the monitor. Attempting to use it the other way is about as productive as trying to download more RAM 💡 The latch is great for stability, but don't try to muscle it out. Always press the release button before pulling it out of the port to avoid damage 🛠️ The 18 month warranty is a nice safety net for the price. It has worked well with my setup for presentations and extending my desktop 📺

Easy to connect and worked right away. The picture is clear and stable, and I haven’t had any connection issues. It does exactly what I needed it to do.

Here are the pros and cons of the BENFEI 4K DisplayPort to HDMI Adapter: Pros: Compatibility: Allows devices with DisplayPort outputs to connect to HDMI displays, facilitating compatibility between newer and older devices. 4K Support: Capable of transmitting video resolutions up to 4K (3840x2160) at 30Hz, providing high-definition video output. Audio Support: Transmits audio alongside video signals, allowing for a seamless multimedia experience when connected to HDMI-equipped displays or audio systems. Plug and Play: Typically requires no additional drivers or software installation, making it easy to use and suitable for quick setup. Compact Design: Often features a compact and lightweight design, making it portable and easy to carry for presentations or travel. Cons: Refresh Rate Limitation: At 4K resolution, the adapter usually supports a maximum refresh rate of 30Hz, which may be lower than the native refresh rate of some displays, affecting smoothness of motion. Unidirectional: As a uni-directional adapter (DisplayPort to HDMI), it only supports video and audio output from a DisplayPort source to an HDMI display, not the reverse. Compatibility Issues: Some adapters may not be fully compatible with all DisplayPort and HDMI devices, particularly older models or those with specific firmware requirements. Cable Length Limitation: Depending on the model, the length of the adapter cable may restrict placement and flexibility in connecting devices. No Power Delivery: Typically does not support power delivery, meaning it cannot charge or power devices through the adapter itself. Before purchasing the BENFEI 4K DisplayPort to HDMI Adapter or any similar product, consider your specific needs for video resolution, refresh rate requirements, and device compatibility. Checking user reviews and ensuring compatibility with your devices can help avoid potential issues and ensure a smooth connection and performance.

I bought this adapter for my new Dell computer. We run dual screens and only had one HDMI port for monitors. The other was a display port. I only had HDMI cables so I ordered this. My second screen would sometimes come on but mostly would not. I assumed since it.was.a.new.adapter, that the computer was at fault. Got online with tech support and they had me send computer back to replace motherboard. Got.it.back and all was well for a couple weeks. Called again and to stop this long story, after 3 months off headache, I ordered a new display port to HDMI cable and eliminated the adapter. No more issue. I would not purchase this adapter as it has been bad right out of the package.

Very good product. Working well. I had procured one from local shop for the same price, but it did not work. This is a good item

Der BENFEI DisplayPort-auf-HDMI-Adapter funktioniert bei mir einwandfrei. Die Installation war denkbar einfach – anschließen und sofort wurde das Bild ohne zusätzliche Treiber erkannt. Die Bildqualität ist hervorragend. Das Bild wird gestochen scharf übertragen und ich konnte keinerlei Störungen, Flackern oder Aussetzer feststellen. Auch bei längerer Nutzung bleibt die Verbindung absolut stabil. Der Adapter macht einen hochwertigen Eindruck und sitzt fest in den Anschlüssen, sodass es keine Wackelkontakte gibt. Genau so sollte ein Adapter funktionieren. Wer eine zuverlässige Lösung sucht, um ein DisplayPort-Gerät mit einem HDMI-Monitor oder Fernseher zu verbinden, kann hier bedenkenlos zugreifen. Ich bin rundum zufrieden und würde den Adapter jederzeit wieder kaufen.

Bez problemu działa z terminalami Dell, inna przejściówka dawała tylko obraz.
