Review on Plugable Active DisplayPort to HDMI Adapter - Seamlessly Connect DisplayPort-Enabled 🔌 Devices to HDMI Displays for Crystal-Clear Ultra-HD Video Streaming (4K 60Hz Support) by Matthew Fadoul

2020-2021) which only has Mini DisplayPort outputs. I connected it to my HDR10 capable 4K HDTV and expected 4K and HDR10. Instead I got 1080p with HDR. It turns out my DP to HDMI adapter only supports 1080p. After wondering what the difference between Displayport -> HDMI adapters and $5-$50 cables might be, I did some research. The Displayport signal and HDMI signal are completely different, but since it was originally designed to be cross-compatible, the Displayport can output HDMI (through), and the adapter only needs to do some work to change the voltage and to transmit the signal (called "passive" adapters). However, that was before. on the. Now that a huge UHD signal requires every bit of bandwidth, you can't stream all 4K 60Hz over the same port. That's why there are "cheap" adapters and "not cheap" adapters. What is the difference between adapters that support 4K@30Hz and 4K@60Hz and 4K@60Hz with HDR? and adjust, the adapter must fully translate the Displayport language to HDMI, both incoming and outgoing. So there will be a difference between low-end, mid-range and high-end adapters because in each tiny computers do a lot of work and some do more than others and some do better etc. Realizing that this adapter is doing an intermediary, which controls if the picture is good or smooth or sometimes not working etc. I did some research and found that this (plug-in) is a decent brand and the adapter does what I need and is reasonably priced and there was overnight delivery. So I have it. What can I say? I work, I'm happy. If you need a DisplayPort to HDMI adapter with 4K 60Hz HDR support, this looks like the best value.
