HDMI to USB C Adapter Cable 6.6ft 4K@60Hz with USB Power Adapter,HDMI Male to Type C Male Converter Support Touch for New MacBook Pro,Mac Air,Nreal Air VR

Why I bought this: I have 3 computers all hooked to 4 monitors. 2 of them use my 4K TV/monitor with HDMI 2.1 for 4K 120Hz. However, my main monitor for my work PC is my 3440x1440 ultrawide. I do not care about the resolution, but the extra real estate so it displaying in 2560x 1080p with a cheap HDMI isn’t a problem. However, as the second monitor or when ultrawide is beneficial in games with my other PC’s, that monitor I want the highest resolution and frame per second I can get. My ultrawide monitor also has a KVM featureThe problem: my main gaming computer is the more powerful and as such, utilizes the ultrawide’s only DP port for 3440x1440 144Hz gaming. The HDMI ports only offer 100hz at that resolution but because the HDMI ports on both gaming computers are utilized by the 4K monitor, I tried going DP to HDMI from my backup/second PC but anything that said 2K at 120 or 144Hz would only display the picture in 2560x1080p at those refresh rates. If I change led it to my monitors true resolution, my max refresh rate was 60HzWhy this was the solution: my ultrawide supports USB-C A/V input. Remember I mentioned my monitor also has a KVM switch? That feature that combined with my physical KVM switch I already had, allows me to utilize the same mouse and keyboard with all three computers without adding more wires on my desk from a second manual switch. So, this cable allowed me to utilize my monitors built in KVM function, being able to plug the USB-A into my second computers motherboard to send mouse and keyboard commands and the DP on the video card the other way through the single USB-C into the monitor. I got the resolution (3440x1440p) I wanted as well as the KVM feature. There was a slight performance cost however.This solved my issue of running two cables to have the KVM and A/V, as well as reduced resolution (2560x1080p) when using a 144Hz rated 2K (2560x1440p) cable. In case you don’t know, the extra width of the monitor adds to the pixel count, which increases data for each frame, which lowers the rate at which the cable can transfer more data. To keep the same higher rate, it lowers the pixel count.This cable allowed my to send 3440x1440 A/V through USB-C to my monitor at 95Hz. Its not the full 144Hz my monitor is capable of but it didn’t limit me to 60Hz like DP to HDMI did. So for me, while I will still look for a cable that will meet the KVM and DP to USB-C functionality but support full resolution at the full refresh rate, I will happily use this until I find what I’m looking for or maybe, just maybe the manufacturer will see this and will create or suggest if already available a similar cable with a higher data transfer rate.

Did you know that pretty much all HDMI to HDMI cables are bidirectional (ie; doesn't matter which side you plug into the source vs. destination), but nearly all HDMI->USB-C cables are unidirectional (ie; one end is for the source of the video, while the other is for the destination/display)? It turns out that USB-C to HDMI cables are common, but HDMI to USB-C is not. That is because most monitors have HDMI as an input, not USB-C, so the cables are meant to have the USB-C end plugged in the PC (source) and the HDMI end plugged into the monitor (Destination/Display). Portable monitors, on the other hand, often just have USB-C ports for power and input, and no HDMI ports. In my case, my laptop only has one USB-C thunderbolt port, which I need for a hub to plug all of my other peripheral devices in (thumb drive, ring light, webcam, external speaker, etc.). Therefore, I could only use the HDMI port on either my hub or my laptop to attach my portable monitor. This requires either a bidirectional HDMI<->UCB-C cable, or a unidirectional "HDMI to USB-C", which is the opposite of most cables on the marketplace.This is the FIRST cable that actually WORKS with my portable monitor ((HDMI to USB-C). I admittedly initially purchased a few USB-C to HDMI cables, as I did not know about the unidirectional issue with these cables. Those initial cables obviously did not work, but not due to any fault in the cable itself, as they were meant to work in the opposite direction that I needed. However, since then I purchased SIX (6) other cables that were clearly listed as "HDMI to USB-C", and this one is the ONLY one of those 6 that worked! I tested this cable with a direct connection to my laptop, as well as through the HDMI port on my USB-C hub. Surprisingly both work just fine (many HDMI to USB-C cables have a disclaimer that they won't work through a hub). However, I must say that my USB hub gets REALLY hot when going through that way, so I wouldn't recommend using it through a hub unless the hub is designed to handle it. In my case, I plan to use it plugged directly into my HDMI port, so that won't be an issue.

This DisplayPort to USB C cable has been a great addition to my setup! It works perfectly with my Mac, allowing me to connect it to a 4K monitor with no issues. The 6.6ft length is ideal for flexibility, and the picture quality is stunning at 60Hz, making it great for both work and entertainment.The included USB cable adapter is a nice bonus, adding more versatility to the connection options. I’ve had no problems with signal loss or lag, and everything runs smoothly. If you’re looking for a reliable and high-quality cable for your Mac, this one is definitely worth it!
