    • Only have DisplayPort? No problem!
We bought this product specifically for a PC connection. It is stated that it will not work for consoles. That being said... It works flawlessly can handle the high performance from DisplayPort (gpu) to monitor or capture card. Currently, we're testing it out to utilize a dual capture card setup. Internal capture card for main streaming and external capture for discord and tiktok live. The connection is excellent and you can't beat plug and play devices. The video brightness and quality is 1:1. There is no lag in the connection speed and can handle 2k and 4k displays. It is very portable and removable. Highly recommended if you only have an HDMI connection for your monitor or TV if the PC is hooked up. ... show more

    • If you're having trouble using a Displayport to HDMI adapter, THIS is what you need.
I just wanted to share some information with people that I wish I'd had when I was putting together my most recent project. I recently built a four-screen computer monitor display, using four Acer 24" LCD screens. Two of those screens had HDMI connectors, while the other two only had DVI and VGA. My video card, a Nvidia GeForce 1070 GTX, had three DisplayPort connectors along with one DVI and one HDMI. I was able to readily connect a DVI-to-DVI connection for one screen, and used a DVI-to-HDMI adapter for the other. This left me with two HDMI only screens and only the remaining DisplayPort connectors for the other two. I initially just bought a passive DisplayPort-to-HDMI cable for each of those screens, but when I plugged in everything I received no signal on the screens and my PC didn't detect them. After much research I found that the 1070 GTX video card doesn't have what's called DP++ connectors, which means I needed an active adapter. I bought two of these adapters, plugged everything up, and I have a nice four screen setup with no further fuss. If you're trying to use the DisplayPort connectors on a 1070 GTX to go to anything but a DisplayPort connector on your screen, like me with having to adapt to the HDMI connectors, don't waste your time buying anything but these adapters. They work perfectly. ... show more

    • A Solid Choice for an Adapter
I purchased this DisplayPort to HDMI adapter back in 2018, and it has performed exceptionally well for my portable monitor (used as a secondary monitor during gaming for btop). This adapter delivers solid and reliable performance for most of my display needs. Key Features I Tested: Resolution: It supports up to 2560x1600 without any issues. Refresh Rate: I was happy to find that it works flawlessly at 120Hz. HDR: Unfortunately, HDR is not supported at this resolution and refresh rate, but this limitation is understandable for an adapter of this type and age. And by not supported, I mean that you can select HDR but the screen goes completely wonky. Plugged straight in, HDMI-to-HDMI, HDR works how one would expect so it comes down to the adapter. Despite the lack of HDR support under those conditions, this adapter remains an excellent choice for secondary displays. It has been durable and dependable for years, and I highly recommend it for anyone with similar display requirements. If you don't care about HDR, consider this a 5-Star review. ... show more

    • Works like a champ
Active DisplayPort is what you need to keep your stupid television from displaying "NO SIGNAL" when your computer is most definitely outputting video! This adapter worked out of the box to connect my HP EliteDesk running Linux to my 4k TV.

    • Works as full 4:4:4 RGB adaptor for compatible TVs/monitors
I'm not sure why Amazon wanted me to rate "sheerness" or "thickness", but, um, both were ok. More importantly, this is an ACTIVE adaptor and so allows use of a 4:4:4 compatible TV/monitor with a DisplayPort graphics card. Current graphics cards typically have only one HDMI port. If you want to drive two HDMI monitors at 4K, this adaptor does the job. If you use a passive adaptor, you won't get full 4:4:4 color and computer text will likely be multicolored versus black. A passive adaptor won't work. As always with Cable Matters, it works and is reasonably priced. Note: most TVs don't support 4:4:4 color, so check the specs. And TVs that DO support 4:4:4 may do so only on one HDMI port and/or it must be set for "advanced HDMI" or similar. ... show more

    • Yet Another Solid Product from Cable Matters.
We needed DP to HDMI conversion with timing correction for my wife's work HP laptop docking station as it only outputs VGA or two Display Ports. We wanted to connect a 4K 55" Roku TV to it as a big monitor / TV to the HDMI. She had two 28" monitors, but her new office area at home was a little smaller and using the TV as a second monitor gave MUCH more room. AND it let her go to 4K video and see everything well, and room for even more open apps/windows. It works great with the TV, her computer had no timing issues with it as we had with a cheapie adapter. (Not that this is really expensive) Working great and worth the money spent. ... show more

    • Use Warrky DisplayPort to HDMI Cable Instead!
I purchased a HP Thunderbolt Dock and two monitors for a dual set up. Once I received the Dock, I discovered that the dock only provided DisplayPorts for the monitors which only had HDMI connections and accompanying cables. Therefore, I purchased two Cable Matters Display Port to HDMI Adapters. The adapters did not work properly. Every time I booted up my laptop, I was required to disconnect the HDMI cable from the adapter and then reconnect it to utilize the displays. I contacted Cable Matters and they claimed that it was my expensive hp dock which was the issue. Before I went down that rabbit trail, I decided to purchase Warrky's 4K DisplayPort to HDMI cables and see if the problem persisted. I also posted a question on Amazon and was answered by others who either had the same issue or worse. One reviewer told me that "at least yours works!" I then ordered the Warrky cables. I COULD NOT BE HAPPIER WITH THESE CABLES! Not only did Warrky's cables work wonderfully once implemented, but the braided cables are what one generally receives with the much more expensive offerings. They are very durable and eye catching. I work in the IT field and will recommend these cables to all of my customers. I am thrilled to be given such a product that works as designated, is high end, and sold at a very affordable price. ... show more
