Except... it has very little to do with the TV. You can throw all the hardware specs, and marketing jargon you want to around. That still doesn't change the fact that SD (Non HD) Programming was never recorded at 1080p, and never intended to be upscaled on a screen with almost 10x the pixel density. The older the content, the worse your signal is going to be. Unless you're spending multiple thousands of dollars on a high quality dedicated scaler, you are going to have a blurry image on that non HD content. If you have an issue with HD programming, that is a separate issue.
