I am using this on a AMD 295X2 GPU and hooking it up to a Samsung 50" 4K Smart TV (un50ku6300fxza) and it works perfect, and is allowing for a 4K display. Even though the TV supports 120hz, it looks like this Insignia device won't go past 30hz (but for casual viewing and some gaming it's OK). Worth the $25 if you are in a pinch. These pictures uploaded are actual screenshots of the device being used. Note: You will need to play with the resolution a bit to get it the way you want. At first I went with 3840x2160 and 300% scale, but after playing around with everything as some program text were too small or blurry, I decided to go with 4096x2160 and 175% scale seemed to be the happy medium (but that was because I am using a TV and not a computer monitor.

Got this to connect a new monitor to an old MacBook. It did the trick!

Added a second display now running three off of my iMac. This is a must have to accomplish this.

This product was great for taking what's on my Mac screen and putting it up onto my tv. Just plug it into the thunderbolt port then to the hdmi cable on your tv and it's that easy. Plus it's super good quality and made out of good materials and doesn't seem cheap at all.

I installed in my old mac book and conectef to the big screen tv so Far no peoblems. Good image quality and fast response Good for my cad projects Recommended
