Review on Cable Matters DisplayPort Eyefinity Technology by Jose Cruz

. I'm surprised it was reliable, especially since Dell's own active adapter and others are much bulkier and require a separate USB power supply. To do this, it is very important! (Note that there are many passive adapters that are similar in size but fail or produce low-resolution snow artifacts when plugged into a monitor larger than 1920 x 1080. This cable is the one.) Others that do successfully used on higher resolution monitors, please provide your feedback. Has anyone used it with a 3840x2160 monitor?
