I have another switch that supports 30Hz and works fine with older Macbook models. But I recently got myself a Macbook Pro 2020 and to my surprise found that my existing switch doesn't work with it - the monitor only shows "OK" for a few seconds and then turns completely green. Thought it was a flash rate discrepancy decided to try this one which supports 60hz and am glad to know it works! Now I can switch between the latest Macbook and the portable PC. The optional switch control is the icing on the cake and very convenient. Super happy.
