Very good product, 1440p 120hz
Product does its job, allows me to connect my 1440p 144hz screen to my laptop. The data rate is limited to 120hz due to the physical limit of the cable, so no 144hz, but that was to be expected in the product specification.
This cable probably allows 1080p 240hz or 4K 60hz, so it's a very good product that I recommend, except of course for those who need 8K or 4K 120Hz, but you might as well use DisplayPort for those extreme cases.
