Review on 🔌 4K DisplayPort to HDMI Adapter Cable (2K 60Hz, 1080p 120Hz) - WARRKY Uni-Directional High-Speed DP to HDMI Converter for HP, Dell, GPU, AMD, NVIDIA, and More - Male to Female - Passive by Ronnie Saylor

So far so good. I have a GTX 1080 Ti graphics card and it has 3xDisplayPort and 1xHDMI. I wanted to keep the HDMI port for connecting my VR headset directly. And I still wanted to be able to connect my 4K HD TV as well as my extra ultra wide monitor that only uses HDMI. I could hook up an HDMI monitor for a monitor to the motherboard HDMI port and use the onboard graphics on my Intel processor, but I prefer to connect to my GPU so I can control resolution, refresh rate, and colors from the Nvidia control panel can. So I bought two of these to connect both a TV and an extra monitor. I am happy to report that I received more than what was stated in the product specifications. The product specs say it supports up to 30Hz at 4K, but it doesn't. When I use it to connect to my DisplayPort graphics card and to my 4K TV with HDMI, I get the option to enable a 60Hz refresh rate for the TV. And when I hooked it up to my ultra-wide monitor, I was able to run it at 75Hz in its native 2560x1080 resolution, so the refresh rate at that resolution is fantastic too. I then tried just connecting the ultra wide adapter to the adapter to see if I could get G-Sync to enable FreeSync on the monitor and I had no way of doing this, hence my guess I don't think it supports FreeSync. Finally, my TV supports 10-bit HDR HDMI 2.0. When trying to enable HDR in the Windows 10 display settings it didn't turn on, although it recognized that it was an HDR capable display and gave me a switch for it. When I press the switch it turns on and the screens go black for a short second and then back to normal and the switch turns off again. While this adapter allows Windows to communicate with the TV and know that it supports HDR, the f-adapter itself does not support HDR signal transmission. To recap, although the adapter's specs say it only supports up to 30Hz at 4K, it actually supports 60Hz instead and also supports at least 75Hz at 2560 x 1080p ultra-wide. Since I don't have a display that supports higher resolutions and refresh rates via HDMI (my gaming monitor only does it via DisplayPort), I can't test and verify other resolutions and refresh rates that it can actually support. And finally everything. here I will note that I am aware of some of the problems reported by other users, that it crashes after a short time and such, so for now I will say that the product works and performs more than advertised, but if something happens in it in the next I will be returning here in a few weeks and will update my review to reflect this. Thank you for reading.
