In terms of image quality, with its native WUXGA 1920 x1200 Full HD resolution in 16:10 format, the Epson 990U delivers. The images are sharp, not loosing any noticeable sharpness as one compares the corners to the center of the image. 8 point text gets pretty soft but it’s a size so small and it’s almost never used in presentations, documents, etc. The 10 point text was still a little soft but you could read it clear as day, which is what matters most, especially for spreadsheets and other documents. To my eye, the text starts to look really sharp by the time I’m using 12 point, and continues to get sharper as the size increases.
All in all, between the performance of the colors and the sharpness on text, I would say Epson has done a solid job here giving teachers a bright, sharp projector that will accurately transmit the colors in their presentations, while making it easy to read for students and bringing any images to life with all their details.
