BENFEI HDMI to DisplayPort, Uni-Directional HDMI (Source) to DisplayPort (Display) Adapter 4K@60Hz/2K@144Hz/1080P@165Hz Compatible with Laptop, Xbox 360 One, PS4 PS3 Device

First of all, let me make it clear that I am reviewing the HDMI to DisplayPort adapter. The Raspberry Pi has an HDMI display connector, and I am using the Benfei to see the Pi's video on a monitor that has a Displayport connector. To get HDMI video to appear on a DisplayPort monitor, you need more than just a connector. The Benfei actively converts the video from HDMI to DisplayPort. It has a USB power connector to power the electronics that do the conversion. My Asus monitor has HDMI and DisplayPort connections. My regular home computer uses the monitor's HDMI port, and the Benfei lets me connect the Raspberry Pi's HDMI connector to the monitor's DisplayPort. It works fine. The Raspberry Pi 4 can drive the display at its 2560x1440 max resolution. (Sorry, I don't remember whether the Pi 3 video supports that resolution.) The Benfei has a USB cable that must be connected to 5 volts. That can be done with one of the Pi's USB ports or with any regular 5 volt supply. The Benfei draws 120 milliamps from its USB connection. To use the Benfei with a Raspberry Pi 3, the connections are Raspberry Pi HDMI port Benfei device DisplayPort to DisplayPort cable Monitor DisplayPort connector The Raspberry Pi 4 has Micro HDMI, so I had to also buy a Micro HDMI to HDMI adapter cable.

It works well, granted I'm not stressing it much. Using it to run a 1080p 20" secondary monitor that mainly displays static images for my gaming setup, so I have no idea how this would perform running a 4k TV running a game or something, but for my use case it works well and I have had zero issues with it! Even when I'm watching videos on that secondary monitor I've had no issues whatsoever. No hitches, hitches, visual packet loss, overheating of the device, etc. Again, I'm also not stressing this thing at all. Very low workload. Make sure you do your research however as these are unidirectional and need a separate power source via usb-a. In my case that was perfect.

Works flawlessly. Purchased a laptop with HDMI out. My external monitor supports both HDMI and DisplayPort. The HDMI only goes up to 60Hz. The DisplayPort goes all the way up to 165Hz. Instead of buying a new monitor that supports 2k 240fps and 480fps at 1080, I decided to purchase this for the time being. Works great. The male USB A connects perfectly to my turtle beach stealth hub for power. Highly recommended. Check out other adapters and you'll see that they probably don't support the same high refresh rates pertaining to the given resolutions.

The adapter arrived very nicely packaged. The adapter is very well made with the hdmi adapter side a black aluminum housing protecting the powered conversion chip. Keep in mind, this adapter is ONLY for an hdmi source (dvr, laptop computer, etc.) with a DisplayPort input (monitor or input to a recorder, etc.). A DisplayPort cable (DisplayPort plugs at each end) is required to connect the adapter to the input side. It will not work from a DisplayPort source to an hdmi input, don't even try it. Benefi Makes an adapter for that situation also. I know that because, I bought that one first thinking it was bi-diectional . . . It isn't! The adapter works well with 4k, 30Hz video. My DVR doesn't have 4k, 60 Hz to confirm if this works or not. The one thing that needs to be improved is the USB port hookup. Most DVRs only have one USB port on the back which is reserved for a wired/wireless mouse/keyboard connection. Luckily, the front of my DVR has a second USB port for connecting a USB drive for downloading video from the DVR. That means for the times I need that feature, I have to find a monitor hdmi port (ie disconnect one already in use, hence the need for the DisplayPort adapter) and find/relocate an hdmi to hdmi cable to connect the DVR, then relocate the USB mouse/keyboard connection to the back of the DVR where the DisplayPort adapter was previously connected. Not difficult but a PITA if a separate hdmi cable is not readily available, or if this situation comes up more than once. Benefi needs to have the USB connection as a "Y" cable with power and data going to a second USB receptacle. Only power should be needed by the adapter, not data, so the data lines would be a straight pass through. A separate USB hub would have to be purchased/re-purposed to fix this, but updating the adapter to eliminate this need would be the best approach for the customer buying this adapter.

This doesn't work lol. Don't waste your time or money trying this. Didn't even display output at all on my brand new series x console. However, it did work using my elgato as a middle point, which did not work with 1440p 120hz. My monitor is 165hz -_- 4k. Don't buy this trash device

Bought this because it was the only product that others had found success with for their Oculus Rift S. My laptop has a 2060 that is only connected to HDMI (no DP over USB) so this was my only option. AND IT WORKED! The Oculus software detected my Displayport connect instantly and after an unplug-replug cycle it was ready to go. I experienced no issues with picture quality or framerate. Suggestions: The USB power plug isn't used for data, but instead to help power the adapter. DON'T plug it into your PC. It will take too much power from the built-in USB hub so the Rift S won't have a stable connection. This could cause audio and controller tracking dropouts. Instead, plug it into a USB wall adapter (phone charger) maybe with an extension cord if it isn't long enough (it's about 18 inches). Troubleshooting: If the headset is black or glitches out, try going into the Oculus software -> Settings -> Beta -> Restart Oculus and it should be fixed.

This is a review of the product in reference to Oculus Rift S on my Acer Nitro 5 AN-515-55. I like many others mistakingly bought an Oculus Rift S thinking it would be HDMI capable. After realizing I would either need to sell the headset or find an adapter I searched tirelessly through the internet. Most forms I came across stated an adapter for DP to HDMI would be impossible due to the amount of information that needs transferred. I took this at face value and looked for USB C or 3.0 connectors instead with no luck. Luckily I did come across this listing and I can say this works 100%. The refresh rate is definitely 80hz and the resolution is great. It feels just like an Oculus Quest. I played about 2 hours of Skyrim VR and Borderlands VR prior to this review and encountered no issues. (P.S. if you get a black desktop screen in the Oculus software make sure the app is running on your CPU instead of GPU in "Graphics Settings" on windows) All in all I couldn't be happier with the product but I will be upgrading soon since a GTX 1650TI isn't great for VR. I would highly recommend this product for Oculus Rift S users.

The adapter worked as advertised and matched the PC resolution to the capabilities of the Dell display as expected. As long as there was a signal present at the output of the computer there was no complaint. HOWEVER, as soon as the computer monitor output went to sleep the adapter stopped passing the EDID information from the display back to the Graphics card in the PC, and then the PC resolution would change to another (higher) resolution that the monitor would not accept. This causes an error message to show on the display and the display would never go to sleep. A mouse movement to wake the display would NOT bring the monitor back on. The only way to get the monitor back was to cycle the power on the monitor. I bought another brand unit for the home PC to monitor that does not have this issue; I will keep this unit in my kit bag for a rainy day.

Oldukça işime yaradı. Kaliteli, Teşekkürler

Habe einen Asus VG248QE Monitor mit 144hz und wollte gerne auf der PS5 mit 120hz Spielen. Leider sind die aber nur über den DisplayPort erreichbar und nicht über HDMI. Habe sehr lange im Internet nach einer Lösung recherchiert, bis ich auf diesen Adapter gestoßen bin. Habe ihn bestellt und ausprobiert und siehe da: Es Funktioniert ! Wichtig ist das man in der PS5 die Auflösung auf 1080p stellt und den Leistungsmodus aktiviert und natürlich ein spiel startet, welches 120hz unterstützt. Seit dem neuen Update wird auch kein EDID mehr benötigt einfach den Adapter in die PS5 und zum Monitor ein DisplayPort 1.2 Kabel. Fertig!

ビデオカードがDisplayport、モニタがHDMIは沢山あるけけど ビデオカードがHDMI、モニターがDisplayportは少ない ちゃんと映りました。値段も手ごろで買って良かったです。

My Dell U2722D monitor failed for the third time in 3 months. The the last two with "No HDMI signal from your device". I bought this to tide me over till I decide how to get my money back. This device plugs into the HDMI socket on laptop, power from a high output USB power source and outputs to a female Display port (DP) into which is plugged a DP lead which goes to the monitor. It works perfectly with colours as expected. However, I do not know if it would cope with a higher refresh rate than 60Hz at 2560x1440 which is the highest that this monitor which has a great display will go to. It seems fine with photos and movie DVDs at this setting. I have not tried with the USB power output from laptop which according to the website may not supply enough power. I hope this helps someone. (EDIT: It is a black one not grey, it just looked grey with its plastic cover.. There is no sign of it getting hot as some people have reported.) EDIT: I accidently ran it with the power supply turned off and it worked fine at resolution mentioned above, presumably getting power from HDMI socket. Probably better not to risk doing this in the longer run.

Works flawlessly with the xbox series s. Hook your monitor up though this cable. (You need a display port cable, not a hdmi) Go to Settings, General, TV & display options, Video fidelity & over scan, and then under Display, set the overrides to hdmi. Go back to the 'TV & display options' and here you can set your 1080p 120hz. I don't have a 1440p monitor so I can't test if all the resolutions are perfect but it works amazing for me and my resolution. Very happy 🙂
