I am trying to calculate percent deforestation in tutorial but get a processing error. I believe it is because the file name has already been used, though I can't read the error scripts because I have a high resolution screen (4K). I have tried over-writing the outputs of geoprocessing - to no avail. My biggest problem lies in the fact that arcMap software doesn't work well with 4K resolution, therefore, text within certain windows is unreadable (scrunched together). I believe ESRI is working on resolving this software issue. Does anyone know?
