Resolution when stretched across multiple monitors

Recently, I noticed an issue where if cesium is stretched across multiple monitors the entities start to become pixelated. Sorry for the lower quality image, it was taken with a phone. The first image shows the entities becoming pixelated stretched accross multiple screens. The 2nd and 3rd image are the same entities, zoomed in close but on one monitor, and you can see no pixelation in the border of these entities.
