DisplayPort 1.4 to HDMI 2.1 8K/60Hz or 4K/120Hz HDR Active Adapter

26 Oct.,2023

 

Excellent product and works as advertised, but it took some finessing on my part. If you're like me and running a haswell i7 with 4600 graphics (or similar cpu) on a windows based laptop, this adapter will not work out of the box for you. Step one is too make sure you're using the proper hmdi 2.0 port on your monitor/tv. (mine is hdmi 1 port on my vizio tv). Then you'll want to 'search for updates' for your intel graphics. After that open the Intel HD Graphics control panel. > go to display > custom resolutions > set the width to "3840" and the height to "2160" and refresh rate to "60" (**make sure the correct display is selected in the display drop-down menu on the left hand side**) > next you'll want to set the 'Timing Standard' to CTV-RB (VERY IMPORTANT) > finally click add and go back to general settings. Select the resolution you just entered and the refresh rate should be available. I hope this helps!

Works as advertised! I needed this for my Titan X Pascal because I'm using HDMI for my 4K display and needed another HDMI port for VR and Titan X Pascal only has one HDMI port. I have it plugged into the display port and my DXDiag is saying my display is 3840 x 2160 @ 60Hz.

Great product and fast delivery. I thought I was going to have to wait weeks before it arrived from China. No, came from right in Ohio, USA. Saved me from down time with fast delivery.

It actually works! tested with: Sapphire Pulse RX Vega 56 graphics card (display port 1.4) Vizio E65 TV 25 feet HDMI extension cable + 3 foot HDMI patch cable = 28 feet total Verified working: 3840×2160 at 60 Hz SDR ( aka HDMI 2.0 ) 3840×2160 at 60 Hz HDR ( aka HDMI 2.0a ) Absolutely delighted. My graphics card could not reliably hold a connection at 28 feet of cable with anything greater then 1080p, but this dongle does it easily with 4k HDR at 60 Hz! I have purchased other adapters claiming HDMI 2.0b, but none were able to do this even with a 6 foot cable. Just delighted with this one!

I was looking for a DisplayPort 1.4 to HDMI 2.1 to display 120Hz HDR. This adapter works like a champ! I would highly recommend this to anyone looking for 4k 120Hz.

These do work as suggested however please make note that they DO REQUIRE an additional USB port. These are ACTIVE (powered) adapters and I use 3 for my home cockpit. So I needed a new hub to power them. They work as described.

First let me say that the product is working perfectly but there is a backstory to this. I originally bought this in October of 2021 and was disappointed that it was only passing a 4:2:0 signal from my 6900xt to my LG C1 and had intended to return it (even received an RMA). I changed my mind on the hope that it was a firmware issue that would be resolved as a support e-mail had said the issue may be with LG OLEDs at that time. Well, I don't know which firmware did it but I decided to try this again tonight on a whim and it works great.
