Image quality reduced after upload. (Map layer)

Is it normal that the image quality is reduced when uploading? I mean the map layer. I uploaded the image as JPG and PNG (72 DPI) but it is always blurred after the upload. The image is exactly the same size as the page on Roll20 (in pixels). First of all: - tested with Firefox and Google Chrome - Cache was also cleared - all addons deactivated - 100% zoom in browser I also read the "Best Practices for Files on Roll20" post but ufortunately, I do not recognize my mistake. See here the difference: Thanky in advance! :)

I have now been able to solve the "problem" myself. It wasn't a problem with Roll20 but a setting on my own PC. I set the font in the Windows system settings to 120% (Zoom) and this also enlarged the map. The picture was never displayed correctly as a result. Since I reversed the setting, the quality is now fine again. I think the information could be useful to some.
