Problem with USB-C to HDMI Adapter

Hi,

I have recently switched from a Mac Book Pro 15" 2011 to a new Mac Book Pro 13" 2016. On my desktop I have a Monitor 23" which I use in my work, previously with my old mac book pro I connect it using mini display port to hdmi adapter with no problem, the screen resolution was correctly supported, and I haven't do to overscan or underscan.

With the new Mac I have bought an USB-C to HDMI adapter, but I have problem with it, I had to do underscan, the image is fuzzy.

In the attached Image you can see one of the some problem in the right corner, one I click the icon the pixel return normal.

How I can fix this problem and have a good quality on the monitor? I have tried with a non original adapter, and with the Apple original adapter.

MacBook Pro with Retina display, iOS 10.2.1, null

Hi,

I'm on El Capitan so it may be different, but go to System Preferences > Displays > select "Optimize for" the name of your external monitor. Make sure Underscan is off, and Scaled is not selected. If that doesn't work, try it with Optimize for built in Retina display.
