Review on SunFounder Portable Raspberry Display 13.3" with Full HD 1920X1080 Resolution and 60Hz Refresh Rate by Citylife Harrington

My first impression was that this is a VERY light, very plastic monitor, which gives the impression that it doesn't move well (will take a few beatings), but the picture quality was amazing. The monitor stand is just a wire, but it gets the job done. I connected it to a Raspberry Pi 4 with no problems and am writing a review on this setup. Where I was disappointed I moved to my quiet office, I heard a howling noise. High pitched sound and definitely coming from the monitor. Eventually I found out that it had to do with the brightness. If you increase the brightness to the maximum, the noise disappears. If you need to dim your monitor in a quiet environment, this may not be the monitor for you, but I have no problem connecting it. Now that I've made my decision, I'm very happy.
