I just bought a Toshiba satellite notebook P55W-C with screen resolution 4K Ultra HD 3840x2160. Unfortunately, in this resolution, sketch up does not work well. For example, the Layers window can not be resized, and therefore obscures the check boxes that allow you to show / hide layers. Hard to believe that this program is not set to this resolution. It is a mistake or do not like? (This is a translation, I do not speak English)
SketchUp has been slow to adapt to high-dpi displays. Some progress was made in 2016, but there are still problems that need to be addressed.
