You are pushing the envelope... the pixels are so small that the smallest 'visual impurity' - such as a scratch or a small lint - in the line of sight between display and reading optics and a not perfect view angle - creating reflections / blurs - stresses error correction. Last but not least contrast is an issue as well.
