What is the difference between the 2019 and the 2020 models?

I was able to go through the users manual from Samsung for both the [2019 C34H890WJN] and [2020 C34H890WGN] models. Both manuals are 48 pages long, and almost copy for copy say the exact same things. The most important part is on page 44, the Chapter 10 Specifications. Going from page 44 through 46 cover the screen resolution capabilities and overall specifications. They match exactly. I honestly couldn't find an official difference between the two, however, i'd hope the 2020 version has worked out any issues they may have found in the 2019 but I cannot say that anything was wrong with the 2019 either.

How many watts is it capable to output to a 2018 macbook pro 15,5 inch? oem charger outputs up to 87w. thanks

Not sure of the exact wattage but charges my 2019 15 "mac book pro.
