Hmm, mine's not blurry... I'm actually finding Shield's 1080i/p upscaled content to 4K almost 4K-like (especially 1080i OTA broadcasts, via HDHomeRun). Maybe a little soft, smooth vs. real 4K obviously being sharper, more detailed. Only noticeable when walking up close to the TV, like 5ft away. My TV is a Vizio D65u-D2, not even their more pricey M-series.
