Computer Monitor 4K 30Hz Vs 1080P 60Hz

I have a 27 4K LG monitor that works at 60hz (refresh rate), I previously only had a Mac that could support 30hz so at the time it didnt matter.  Now I have 15 Macbook Pro (2018). I paired the Macbook Pro with a CalDigit Thunderbolt 3 Mini dock with dual HDMI, which youll need if you want to do 60hz with a dock rather than just a USB-C cable/adapter.  I thought any old HDMI cable would work, I was wrong and now I learned there are different capabilities of HDMI cables, basically they vary in the bandwidth they can support.  This cable from IOGEAR supports 4K over 60hz,  so now everything is hunky dory.  I would prefer a thinner cable, but this does what it is supposed to do, and thinner cables dont go past 30hz.

Perfect for 4k monitor, 60hz!

Not fully used yet as i am waiting for a right price 4k monitor above 60Hz.

Nice 4K monitor for the price. I am using displayport at 60hz.

Hard to beat a good ViewSonic monitor. This might be the best value at 1080P 165hz! If it's anything like my past VS monitors, it'll last you 10+ years!

Bought similar adapter after purchasing a 4k monitor, but none of them output above 4k or 30hz. This one allows me to run my 4k monitor, and the quality was an added bonus.

This does exactly what it’s supposed to do. I have a 4K Ben Q monitor and a 2015 MacBook Pro that I have running in another room because of fan noise in my studio. I have an optical thunderbolt cable but couldn’t get 4K 60hz at the tail end of my Thunderbolt Daisy chain. No cable would allow me to get 4K at 60hz at the distance I needed. The longest cable run I could do was 6ft or so and that was unreliable. I got a very short DP cable run directly into the repeater and then I ran a 25ft display port cable outside the room and tacked it to the wall. Works perfectly. Make sure you have the shortest possible cable running directly to this box from the source. This is a great solution and doesn’t require you to spend $350+ on optical cabling that dies after a couple years because the lasers and sensors overheat.

at first i thought the company i leased it from forgot to get me a 4k 60hz monitor but certain hdmi ports are compatible on it. What I am getting at it is 4k 60hz but you need to make sure you have the right cable and you put in the cable in the hdmi port that supports 4k on the monitor. Its all in the manuals

Gives me the 60hz 4K connection to my new external 4K monitor as well as having two external 1GB SSD drives connected. Also cleaned up the wire jungle I had with my old attached hub.

Note that while the pass-through HDMI port will support 4K, the USB signal provided to your computer is only max 1080p. It's perfect for my needs, but if you need 4k on your computer then look for a different device. The 1080p is perfect with no artifacts or other glitches. Highly recommended.
