BENFEI 4K DisplayPort to HDMI Adapter, Uni-Directional DP 1.2 Computer to HDMI 1.4 Screen Gold-Plated DP Display Port to HDMI Adapter (Male to Female) Compatible with Lenovo Dell HP and Other Passive

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.

I have purchased three of these Benfei DisplayPort to HDMI adapters, and am generally very pleased with them. The video is clean. It is sturdy device, and the short cable allows the HDMI cable portion to bend around corners and not put undue mechanical stress on the host device DisplayPort connector. And you cannot beat the price.One minor troubleshooting note that might help others: This adapter is built around an ASL Technology CS5218AN "jitter cleaning" HDMI repeater chip (it isn't just two connectors and wires--surprise!). Active devices can fail spontaneously for no apparent reason, and this happened to me recently. Very weird symptom, with my Linux box suddenly displaying "error: no suitable video mode found" during boot. (It has worked flawlessly for about two years.) After messing around with cables, different monitor, etc., I finally swapped with another Benfei adapter of the same type and the problem went away. Moved "bad" adapter to another computer (also running Linux) and it gave the same error message at boot. My guess is that when the repeater chip fails it messes up the display data channel (DDC) communications and the computer/host can no longer query the monitor for its supported video resolution/modes. (Yeah, I'm an engineer/nerd.) Despite this failure, I'm buying another Benfei adapter and will buy more in the future! But if you do see this error or something similar, at least you'll know what to check first.

I go through a ton of these on installs. They always work and are a good price point.
